4.3L v6 to 5.7 V8
 

Hello everyone, i was directed from iboats.com to search for info hear from a member, hopefully you guys can help. I have a mid 90's mariah 18' boat that came with a 180hp chevy 4.3L v6. Eventhough i have a lot of respect for the 4.3L motor, very solid / bullet proof, our engine never made much power. 2 years ago the block cracked from in proper winterizing therefore I now have a rebuilt 5.7L motor ready to go in but I need a distributor. I sold my thunderbolt 4 distributor. My wiring has a flat plug that went into the 7 pin connector into the thunderbolt distributor. Please let me know what I need / where I can buy a distributor for my 5.7L engine.

Thanks

The Thunderbolt distributors are the same for a V6 and a V8. Just change the wheel under the rotor with the v6 or v8 wheel. Change the caps too of course.
Hope that helps a little.

Thanks Dennis - Unfortunately I sold the distributor since I figured the V6 would not be the same as the V8. I was also told that the V8 had roughly 20 degrees of advancement where as the v6 had a lot less. The forum will not let me post an add in the swap section. Does anyone know where I can find a Thunderbolt IV distributor? See my picture of the v6 distributor that I need a v8 distributor to replace - goal is to find one with a connector such that I do not have to cut the wire harness

I have a spare.

Send me an email to [email protected] and I can send you a pic this evening. Looks like the exact same connections.
