My boy is configuring the engine for his car. He has one of those Explorer crate engines (40P heads). He is going carbureted with a E303 cam and 1.6 roller rockers. His question is he doesn’t know if the stock push rods are the right length with this cam and roller rockers and if not what length? I can’t help him here so if you guys could it would be a great help. Any other comments / suggestions on the engine combo would be greatly appreciated. He is trying hard to stay in some sort of sensible budget, not like his dad.

Thanks,
Mike M.

Stock push rod length will work fine. Make sure you use FFR 4 into 4 headers or the MAC headers for the P heads.

Stock p-rods are fine. f nnot the 4to-4's, the BBK ceramic coated equal length headers are very impressive!
