I have a friend with a stock 70, 350HP 350. He wants me to put a clutch in for him, and I don't know yet if it's a 10.5 or 11 inch clutch. I'd like to order the parts now. Any help is appreciated.

Not much help, but Centerforce lists both for 70 with 5.7 engine.

69-70 is 11" and 70-71 is 10.4.

Hi, mine came with an 11". I have seen the 11" in the 350 HP and 370HP
engines. Not sure what came in the base engine.

If its the original flywheel, you might consider changing that anyway. At that point id go with an 11" flywheel and a centerforce dual friction....right now i have a one year old 11" flywheel that i changed from a 10.4 when i did my motor swap, and i got a dual friction waiting to go in, so im going to resurface the flywheel and throw the clutch in.

you could always resurface the current flywheel if its not too far gone, but 11" would be optimal IMO.
