I'm in the process of gathering all the parts necessary for a c4 to toploader swap in my 76 250 I6 Maverick. The 250 uses the same bellhousing as a small block V8, but from what I understand the flywheel from a 302 won't work with my 250 because the 302 is externally balanced by extra weight cast into one side of the flywheel. I have found what they call a zero balance flywheel online, but they seem to be pretty expensive, and I'm trying to cut costs wherever I can. My question is. Is it possible to just machine the extra weight off of a stock junkyard 302 flywheel? Or does anyone know of any ford vehicles that I might find in my local salvage yard that utilized a zero balance flywheel from the factory? Thanks
I have one from a 300 out of my dad's truck and it's 0 imbalance. You should be able to find one in a wrecking yard.
No, everything I've read says that the 250 flywheel bolt pattern is exactly the same as a 302. It's just the balance issue thats the problem. And There are no 250's in any junk yard that I've been to or called. If anyone knows where I might find one by all means give me a shout.
Are you using the 300 flywheel in a 250/toploader application? I've searched the forum high and low, but haven't found anyone that said that they actually installed one on a 250. One guy bought one for his 250, but then said he thought it might be to thick.
The problem with the 300 I6 flywheel is that is is 164 tooth. You would have to get the whole shooting match with it. Flywheel, bell housing, clutch fork etc...
Yes, you can , but it needs to be done by someone who does engine balancing to be sure it's done correctly. I would also recommend doing this to a new flywheel, instead of one of questionable history. You can buy a new O.E. iron flywheel for a 5.0 for around $100. I did just this with one for my 331, bought a new Ford Racing 5.0 flywheel then had my balancing guy rebalance it to 28 oz/in. Same can be done doing it to zero.
