    Came out today to my carport and my 5 little eager helpers from up and down the road were drumming with my pushrods. Now none of them are in order. What are my options here? New pushrods? new lifters? Its on my new 350 that I am putting in. I took the heads off to get the valve seals done. I have to try to keep this as cheap as possible.

    On another note
    will 307 exhaust manifolds fit a 350??
    Which kind of carb should I use q-jet or edelbrock?
    Should I put electric fans on or should I keep the regular one?

    thanks for all the input

    I don`t think the push rods matter, just the lifters. For the cheap route, I would go with the Q-jet and a regular fan.

    need to find out which one has the most cfm and get that one. Sometimes a smaller one has more cfm than a large one.

    Drumming? Hmmm... If there are any scratches, dings, or dents on the pushrod ends, replace them. Factory replacements are cheap.

    Lifters are the most important, but I would still go to checker or etc. and get new push rods (cheap insurance). You may also want to look at your rockers closely to check for pitting and side wear. Good luck.
