Edelbrock LD340 Intake Manifold Usable Max RPM?

Fish Bite said

Thanks. The main goal of me asking the question is to help determine the cam profile that will impact the rest of the build. A few cam companies I spoke to were thinking for solid flat-tappet in the .535"/255° @ .050" area running at 7,200 RPM. The largest that one suggested is .600"/260° to push up to 7,600. Your thoughts?

It’s hard to judge really because that combo wants 260-270 @ .050 and a big single plane. And I’d want more lift, like .630-.650, but then throw the LD340 on there and I’d want to see 230 @ .050 and .500 lift and 9:1 comp. So I’m gonna tell you to not be set in stone on any of them. Have a cam ground and if it doesn’t do what you want tell the grinder and get a different one ground. And if you’re not rules limited to a SFT, I’d run a hard roller in that thing without thinking twice about it.
