Dan, I was replying this morning when the power went out and then I had to run to work! As mentioned, the battery should be OK but I sure would check the cable and it's terminal. Under the electric tape (never a good sign!!) it looks like the terminal was poorly crimped and maybe not even crimped with the proper crimping tool. Take the tape off and see. Check for corrosion as well. Lot's of cranking and the poor termination sure would cause a "melt down". Besides crimping the lugs on, I always like to sweat solder. It fills in the gaps the crimping leaves behind. As a finishing touch, I will use adhesive lined heat shrink tubing over the lug barrel and several inches of cable. It forms a complete seal. The coil wire had nothing to do with the battery terminal. They would have burnt up real quick long before the battery cable heated up. BTW, both my 54 and 64 have wing nuts on the battery. 65 combined boating years without a single problem using them!!!! |

I know guys running pressurized soft fuel lines. They haven't had any problems in eons either...yet....
That still doesn't make it right. Loose the wing nuts. |

I have always used wing nuts and have never had any issues.Get them tight by hand and as long as electric system is working properly good to go. I am sure everyone has had an issue where starter keeps cranking on a vehicle or there is an electrical program and you have to disconnect battery quick I don't want my boat to burn up while I am looking for a wrench.

Good heads! Closed chamber large ovol port gets the compression up into good range and will flow good through rpm range.You maybe got lucky and someone knew what they were doing. If it has flat top piston should be in low to mid 9's for compression. So many cam choices for lefty motor would be nice to know approximate cam lift. Should be a runner

Brian, "sweat" soldering is just a common term when capillary action is used to pull solder into a joint. Think about soldering copper water pipe/fittings together. A large soldering iron is ideal for lugs on cable. A torch can be used as long as you be very careful to avoid excess heat. I happen to like "Sta-brite" solder and always have a roll of it. It has silver in it that really wets out the joint plus its stronger. |

You can see pics here in the for sale listing I posted (my boat is a Supra so I offered it there first): Holley 9022 800 CFM 4150 double pumper This will bolt on right in place of what you have and you can use the fuel rail you already have to feed it as your existing carb is also a 4150. |

Hey guys just recieved the wrong starter in the mail awesome! Got the right one on order hopefully. Want to get this carb ordered I just cant justify buying a used one I want new so there is no excuses. Trying to figure out what I should be looking for CFM wise and if edlebrock or quadrajet will bolt on to my set up? WOuld love some insight

So got the new starter and it actually sounds like she might start now. The new problem is the wire from the starter solenoid to the starter motor is getting hot and I only cranked it a little bit. I don't want to screw anything up. I think I need to go through all of the wiring. How is the starter supposed to be wired to the coil my goes through a porcelain reistor that is mounted to the intake manifold. There are 4 wires that go to the starter two go to the big post on the solenoid, and one wire to each of the little posts (r, s). From the r post on the solenoid one wire goes to porcelain resistor then to positive post on coil. The neg pist on coil has two wires one to distributor one out of a big pack of wires that run aroound engine even attsching to altetnator. The s post on solenoid is grounded to tranny. Sound right

Dan,
Hopefully you have not installed a deep cycle battery and all your connections are good. Yes, the cables will heat up when you do extended cranking since the factory did go to the min wire size. Again, the problem has been discussed in several threads. Deep cycles are bad for cranking. What type of battery do you have? The voltage drop is bad with the deeps on high amp loads (cranking) consequently the amps go way up (Ohms law). |
