2.02 or 2.05 Intake Valve?
But isn't that for a "maxed out" combination. Solid roller, big single plane, hi compression?
@273 is correct to a degree. While he has a good point on how things generally go, I say No. It’s a CID thing, that’s all. But he’s on it! The rule of thumb is for a serious but still a nice powerful build that is still in the realm of streetable. While the cam shaft does get a little large for some people, it’s really not extreme. Of course, the smaller the engine the more challenging it becomes. So that right there can be the caveat to this all.
Here’s another point of view on it. The Edelbrock Victor head build that top well over 700 hp was done with a cam @255 intake duration. The CID was IIRC, 376.
The trick here was the heads were ported and the compression was maxed out for the competition @ 11.99.
It still ran on pump gas. You can run 11-1 on 93.
But the trick was superior flowing heads and a cam lift that took advantage of it. There was a lot of lift. What ever cam you run with, and knowing how the heads flow, for which trick flow provides there flow sheet, lift that valve at least up to the max air flow area the head offers. Get that baby breathing!
I’m running TF aluminum heads on a .030 over 360 with the flat top pistons at zero deck and a thin head gasket on 93 octane.
What size engine?
I'm going roller. Whether solid or hydraulic. I'm hoping the Trick Flow single plane will be re-released. I saw an Australian website claim they expect it in June. Hoping we get it here.
I suggest a solid roller for the rpm capability. Or a SFT.
On the intake, I am unaware of what the TF intake does or would flow. Pittsburghracer really likes the Edelbrock Victor a lot. He ports them often and has threads on them. I’ll call it the preferred intake manifold at this time. Then there is the Super Victor. It’ll need to be ported.
One intake did surprise him and wrote about it and how good he thought is was and ported it for me and that’s the MoPar M1 single plane. I had it ported with a spreadbore carb usage in mind so there was some left on the table with that intake and sticking with the spreadbore design. Others here have converters the M1 single plane into a square bore and they’re happy with the results.
