I want to put a stroked 400 in my 69 GTX. I have the stock 833 trans and stock bellhousing. I need a clutch, pp, and flywheel. I'm going to use Mcloud products. Will the stuff made for the 440 fit with the 400 stroker or do you need different parts for the 400 block. If I put the original 440 back in the car I don't want to have to replace these componets.

The clutch and flywheel housing parts should all bolt up and work fine on a 400 and 440. The flywheel should work fine on both if its neutral balance 6 bolt - which I would expect it to be. Some stroker cranks are 8 bolt hemi style so be careful you don't get one of those if you want to swap flywheels.

Thank you sir
