I have a question about pushrod length. Not to long ago I bought a 91 Lx 5.0 and it has an FTI cam in it 224/228 Duration at .050 .536/.528 Lift 110* LSA, The block is stock and bored .020 over with srp pistions, AFR 165 heads (never machined) with 1.7 rockers, cobra intake and the deck height has not been machined..
My question is: Is the FTI cam base circle smaller than the stock cam in the 302? Does the FTI cam effect push rod length? The previous owner installed STOCK length harden pushrods.
I know you have to measure to get the correct length but I am curious and seeing how many here had to go with a different length? Do many here still use the stock length push rods, with aftermarket heads and the block not being deck? In this case the block deck height hasn't been changed and if the base circle of the FTI cam is the size same as stock cam, then most likely the stock length pushrods are correct?
