    Hey fellas a buddy of mine is building a budget 350. It's a roller block and he was given a flat tappet cam for it. I know a flat tappet cam will work in a roller block but we don't know what length pushrods itl need to keep the rockers centered on the valve stem.

    Ok thanks! He's still considering going roller but he wants to run this cam for a while until he saves up for a roller setup. So just stocker rods will keep everything in line?

    You will have to check the valve train geometry after lifters are installed! Flat tappet cams are a crap shoot with todays oils and the quality of lifters and cam shaft blanks. Flat or rounded lobes are real common and will cost you a complete rebuild if it happens! Just FYI.
