After reading all the old posts I'm still confused, can someone verify a few points for me. I am shopping for gt40 heads for my 81 351w
Do I have my facts straight? 1.GT40 heads have 63cc chamber. 2.GT40P heads have 59cc chambers. 3.Both are a bolt on using ALL existing valve train parts 4. Either casting will fit with my PCM exhaust manifolds, ei: angled plugs? Also Did the pro boss motor and the later GT40 motor have the same castings and which one Gt40 or Gt40P. Hate to bring this all up again but I want to do this right the first time. Thanks. ------------- You can’t change the wind but you can adjust your sails |

| I have iron GT40P heads on my 1984 351, and the plugs clear the PCM headers by more than the stock heads. |

1. yes
2. yes 3. yes 4. yes All the PCM ProBoss and GT40 motors used the regular GT40 heads. The GT40p's were debuted on the Explorer's and Mountaineers in '98. Theyre a slightly better design than the GT40's, as they flow a little better all around despite having smaller exhaust valves (intake valves are the same size). They also give a little jump in CR. I believe the GT40p's put me right around 9.5:1. I had no problem dropping them right onto my motor- I reused the stock pushrods and rockers. The spark plug angle actually improves clearance to the exhaust manifolds. I got the p's real cheap on ebay ($230). If I were to do it again, Id get them from Tristate Cylinder head for $550. Once I paid for a valve job and upgraded springs, I spent more than that. ------------- |

Posts like this are like putting out the "bat signal" for TRB.
Tim's boss: What's wrong Tim? TRB: There's been a disturbance in the force. Someone mentioned swapping GT40's on CCFan...

Joel,
Tim's email isn't listed or I would have just asked him directly. He's the guy I was looking for anyway. Tim, I looked at tristate today, $540 for the pair. You can find them on ebay for $2-300 plus shipping plus about $300 to have them gone though. tri state it is. Next question will be intake but that ones alittle easier. Thanks for everything. ------------- You can’t change the wind but you can adjust your sails |

I didn't mean it in the sense that someone would intentionally be looking for TRB but more in the sense of poking some fun at TRB for being so enthusiastic about GT40 heads and advanced engine work in general. Eh, oh well. Some things just don't go over right in text. |

I believe Jim in Houston may have been the first to try the p's on a CC- or at least the first to document it.
Alan, feel free to email me if youve got any other questions: TRBenj at gmail dot com. Ive also got an Edelbrock Performer looking for a home if youre interested. ------------- |

I love Tim's enthusiasm. Always there when somebody has an easy or technical question. He's given out thousands of dollars worth of mechanical advice. I'm sort of "mechanically challenged" in some ways, but Tim and several other folks have tweaked my knowledge. Joel's right, Tim's always right there when you need him.

Jbear, the Performer would have fit your '80 nicely, but Im afraid that Alan has spoken for it already. If you look carefully you can find nice ones on ebay for equally short money.
With all the prize money your '80 has surely won by now, Im surprised you dont have a stockpile of engine parts in the garage. Im sure '79 would help with the install  ------------- |

Tim; No prise money yet but.......Last time 79 looked under my motorbox he just laughed. I bet I could get him up for the challenge tho. I'll look on e-bay altho I have never had any success getting anything there. Always afraid I am bidding on the wrong thing. Congrats to 81, he will be adding to an already sweet boat.

Sorry about that jbear, I've learned to make my mind up real fast with this hobby. Seems if there's something thats got your interest you need to jump on it while it's still available.
Just ordered my heads too, I was going to rework my trailer this winter but decided hopping up the motor would be much more fun.

Joel & Co.,
Speaking of Chicken Wings, I just came across $200 worth of gift certificates for Hooters. Gift from a vendor. Catch is I have to use them up before dec 31. So what about getting the chicago area madmen together at Hooters in Downers Grove Some night between xmas and new years. $200 should get us a pretty good start and we'll just split the rest.

Allen for sh*ts and giggles you should cc the chambers on those new heads before you mount them that way you know exactly what it is, no guessing involved that way. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Chris, I'd be glad to do it but the only CC I know anything about is Canadian Club. If you can give me an easy how to I'll give it a try so we can get a real answer to the mystery. ------------- You can’t change the wind but you can adjust your sails |

Get a measuring device in CCs (beaker or flask) fill it to known amount above what believed volume of heads are. Fill chambers, subtract remaining fluid, Viola!
or something like that, Chris will tell you a better or more precise way. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=5164&sort=&pagenum=1" rel="nofollow - 99 |

Measuring device = Shot Gla$$
Fluid = Canadian Club ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1143" rel="nofollow - Mi Bowt |

So it's done with the heads off the engine upside down on a bench. Too simple, that's why I had no idea. Quinner, how many CC's in a shot gla$$?. ------------- You can’t change the wind but you can adjust your sails |

level the heads with the chambers facing up. four bolts with nuts and washers on them work well. Just screw down the nut all the way down on the threads then place a washer on top of it then set the heads on top. Now you have jack screws on all four conners to level the head. Get a syringe at the drug store or off your local junky your choice, it will have calibrations on the side in cc's fill it with water, get the air out of it and line it up on one of the marks so that you know what the volume of water is in the syringe, then squirt it in to on chamber slowly, you need to have the plug in and tightened or it will leak. keep adding water too the chamber in smaller incruments as it starts to get to the top of the chamber, when it breaks over the edge of the chamber then you should be able to read on the syringe how much is left subtract that from what you started with and you have the volume in the chamber.
using a small syringe with finer calibrations vs a larger one, so say a 10-20cc syringe filled severals times is going to be more acurate then a 100cc syringe. or a compination off both, using the small one at the end to get a better resultant. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Will the surface tension of the water allow it to "bubble" over the height of the deck? ------------- |

that is if you add it slow enough but you should be able to see when it is level with the top, then see it bubble up due to surface tension and know to stop, well if you have common sence that is. It will be close enough for all practical purposes, the main thing is the size of syringe and being able to add small amounts rather than larger amounts at a time. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

shot of CC 1.5 oz = 44.3 cc's
so that would be about a 2 oz shot to fill the chambers if they are 59cc ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Common sense huh, now your pushing it.
The syringe thing might work for me, I used to have to give my old Rottie insulin shots for diabetes every morning and may have a syringe left around. You guys will be the first to know but don't hold your breath waiting. ------------- You can’t change the wind but you can adjust your sails |

The method I most observed was similar to 79's with the syringe, but a piece of plexigla$$ was/is placed over the top of the chamber with a needle-sized hole drilled in it. This takes care of "bubble" effect. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

Reid, this is the way i have done it,even without the plexi,there is a large difference between 59cc and 63cc. none of those heads were spot on as to displacment. Quality control not a big issue......... boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

10-4 Doc. Many of the mfrs have listed as much as a 3-5cc range when listing the chamber size on a specific head, and then list one single number as either an avg or nominal fig.
Side Note: Personally, and this is just from several engines we have, I'm big on the higher comp in our engines with these favorable power to weigh ratios. I don't know that I'd want 10+:1 comp in a cruiser under a continuously heavy load, but in several we've a$$embled with 10:5 and greater (theoretical/advertised based on piston and head combo of Keith Black KB-116 domed pistons and D0OE-60cc 351 heads) the results seem to speak for themselves with no knock or detonation even with aggressive timing and torque and acceleration is incredible. Not having another explanation, I attribute it to a continuous flow of cool water and thus the ability to maintain optimum engine temp. Elect ign doesn't hurt either I guess in terms of not fouling plugs and other issues a$$ociated with high CR's in vintage autos, esp when driving slow or heating up. Also, many of us use premium fuel when it's available whether it's required or not. Might as well take avantage of it. In essence, I'm not saying go build a 11:1 ski boat engine, but if you're looking at new heads which just might raise your CR to the 10+:1 range, don't worry about it and enjoy the power, if that's what you're after. We're pulling into Mr.Jbears neighborhood next Tuesday, the 26th, and hopefully towing down our old beater testbed '69 Mustang so that he and whoever can take a fun testimonial mid-50s mph ride. It's the next closest thing to Bill Burgess' nitrous rocket. SS-201 Bill, you out there? I'm also looking forward to planting my butt in jbear's trophy winner. I'm stoked. If you're in the neighborhood, hook up with us please. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |
