Hey everyone, I picked up a project 68-69 Mustang last fall, and I'm just getting around to working on it. I have what I believe to be the original engine which is in pieces, and another engine that has been mostly installed in the boat. I'm having some trouble sorting out the plumbing and wiring and I think it would be helpful to figure out exactly what type of engine the new one is. I have a set of valve covers with interceptor 190hp on them. I believe these were from the original engine. I'm having trouble finding any identifying markings on the newer engine and am hoping for some help. I will post some pics I have taken too.    ------------- 1968 CC Mustang |

It looks like one of those "mixed breed"pound puppies  Figuring that you know it's a small block Ford engine, it has some Pleasurecraft parts like the thermostat housing and some Interceptor parts like the exhaust manifolds. With you not knowing much about it, you maybe don't know if it's a Reverse Rotation engine which would have been original or a Normal Rotation auto engine that got installed with a bunch of marine parts from the original engine. Some hints about rotation would be a picture of the prop or writing down the firing order, but if you were to remove the distributor and take a picture of the gear that would tell you for sure if the engine internally is set up for Reverse or Normal rotation. The Ford casting number on the block inboard and a little above the starter should be able to tell you the engine size and year built. It's easier to read if the starter is off the engine. There could be a whole lot of if's like whether the rear main seal arrangement is right for the engine rotation, whether the starter will be turning it the right way. Also, you must have a raw water pump somewhere in the pile of extra parts, the fuel pump is an AC dual diaphragm marine pump, the carburetor may or may not be marine, the alternator has an external regulator and is "probably" a marine Prestolite. The circ pump on the engine looks like an aluminum automotive pump too. Other little things are noticeable, but this is a start anyways You most likely have a lot of work in front of you to get things figured out but the forum will get you there. Don't be afraid to ask questions |

Thanks for the fast reply! I was able to do some more poking around on the boat today and got some more pictures. The raw water pump I have seems to be original to the interceptor motor. From my research it looks like this type of pump goes on the side of the engine that the alternator is currently on. I have a spare alternator in my parts, and it looks as though it has the correct brackets for mounting on the left hand side of the engine. I also have the original marine internal water pump.  Should I use this internal pump? It looks like it has two extra hose inlets or outlets that are not on the one currently installed. Also, since I seem to have all the interceptor plumbing parts I'm guessing I should rearrange the alternator and plumb it that way? I believe this is the engine casting number.  And here are the distributor pictures for determining engine rotation.   And as a side note, I also have this aluminum Holley intake manifold in the parts. Any thoughts on this?  Thanks again! -Ted ------------- 1968 CC Mustang |

Ted, I know Ken with confirm but from the looks of the gear on the distributor, I feel you have a standard rotation engine. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Ted I think Pete's just testing me, he does that every now and then That gear says it's a reverse rotation engine, so if that distributor came out of the engine in your earlier pictures, your engine is reverse rotation and I figure it's got an electronic conversion in it too. (2 wires from the distributor to the coil as compared to points with just one wire.)
It's a Mallory distributor,probably the original from the interceptor engine |

That casting number is for a 302 block first used in 1971, so you have an engine that uses a 2 piece rear main seal and has wick or helix lines on the crankshaft in the area of the rear main seal. Hopefully it's a marine engine with the wick lines going the right way for a Reverse Rotating (RH) engine, otherwise you'll end up with a rear main seal leak if it's a normal rotation crank with wick lines going the opposite way. Considering the mix of parts you have, you'd really be best off to take the engine apart enough to inspect the crankshaft wick lines, but you could take a chance and run it as is. You have a 50 % chance of having it right And make sure you have a starter that spins the engine the right way. Since it's opposite of a car, you can't just slap a car starter in there. You also probably have the early reverse rotation 302 firing order of 1 8 7 3 6 2 4 5 going CCW around the cap. The other choice would be the later order if it's a later camshaft and that would be 1 8 4 5 6 2 7 3 going CCW again. Plenty of "gotchas" to deal with if you've never seen it run before. There's an Interceptor manual in the reference section or click on the link below to get it It's a 68 manual for 289 engines but a lot of the stuff will be pertinent and you can figure out what you want to do cooling wise, and alternator wise etc. And there's a wiring diagram too http://correctcraftfan.com/Downloads/1968_interceptor.pdf" rel="nofollow - link |

Ken. No, it wasn't a test. I goofed up with my forward and back slashes!  Anyway, I knew you'd be along and correct me if needed.

Great, thanks for all the info, I have the starter off and will test that. I will also be working on the boat again today, so I am sure I will have some more questions soon. ------------- 1968 CC Mustang |

So it's looking like the engine in there is from a pleasurecraft from what I can tell. I tried rearranging the front accessories to be setup interceptor style since I seem to have all the brackets for that but the fuel pump interferes with the raw water pump. I'm thinking it may be easiest to set it up pleasurecraft style but I don't seem to have the raw water pump or bracket for that. I found this listing on ebay, which I know has the correct pump housing, but can anyone identify the bracket? I messaged the seller and he isn't sure what it came off. https://www.ebay.com/itm/164151482483?ul_noapp=true If that isn't correct, does anyone have a line on where I could get this bracket from? ------------- 1968 CC Mustang |

Actually, I just remembered that the guy I bought it from gave me a box with a part he found on ebay, and I opened it up and it bingo. Looks like the right part to me, now I just need to get a sherwood g21... I'm pretty confident that this is in fact a marine engine. The seller told me it came out of a running boat that a tree had fallen on. He seemed like a trustworthy fellow. I have a feeling it must have been a boat with a pleasurecraft. ------------- 1968 CC Mustang |

That looks like the right PCM pump mount and in the picture below you can tell that you have the right timing chain cover with the bosses for that bracket to mount. Right where the ground cable is bolted to is the spot it mounts. You're making some good progress figuring things out

Hey everyone, so I now have the boat plumbed and running. I'm having trouble with the charging system however and I believe I've traced the problem down to the voltage regulator. Does anyone know if the Standard Motor VR166 the correct replacement? Thanks ------------- 1968 CC Mustang |
