340Help!!

roller isn't all crack up like some make it. If the valve springs get weak on a roller cam and you float the valves it pounds the heck out of the pin on the rollers and you ruin a expensive set of roller lifters--hopefully that is all.

A flat tapped cam broken in right and using a oil high in zinc--which is also better for the bearings and pistons--will last as long as a roller cam and cost less and needs less valve spring pressure to run over 6,000 rpm's . For max racing roller cams can make more HP but for your everyday street engine its not needed, IMO

That 800 carb is too big--even the 750 on the afb-eddy doesn't pull over the boosters rightly. 500 and 600-650 carbs are the way to go. One 600 or 650 avs carb would work better and two 500 carbs on an older dual quad intake is perfect--again,IMO

But those intakes are hard to find and then you gotta buy 2 carbs--so get a 650 avs, it work better.

Lets hope the cam isn't wiped, it should be an OK combo with a smaller carb--if you really want a 750--800 carb get a Holley
