Longer pushrod Question

[bax]

Well if its not a smaller base circle cam then I too dont know why I would be having pushrod length issues. That was my only reason for justifing needing a longer pushrod. When I get the rockers I will re measure pushrod length and see what is what. Thanks for the help

I've never put aftermarket heads on an engine because I dont think I am smart enough to figure pushrod length out and dont know anyone that does either, LOL.

So I just keep putting gt40 heads on everything, LOL

I'm running that same cam with stock pushrods and gt40 heads.

I did roast a cam gear last week from comp telling me it could use cast or steel since it's not a forged cam and recommended cast distributor so its a little softer than the cam gear. But this was when they first came out and the melonized steel cam gears became the known gear that worked. That cam is austempered ductile iron.

I built the engine in when they had just switched cam materials.
