Give me a call 989 2137434 and we can set it up, dynoing my 502 today after straightening out un balanced injectors, heading to gas station for fuel in 5 minutes. Testing a new protype hp 500 air cleaner from aember next week then pulling motor off dyno. So will be available soon

At what RPM?
Have my doubts over 900hp out of a 320cc head.

I will confirm size and HP with Jim and post. I see rookie post and evidently knows something I don't or I was misinformed by Jim last weekend. If I'm wrong then I will certainly fess up to it.

See post 50. The engine in question actually made 787hp, with a 340ish cc head. The 900hp number with a 310-320cc head was incorrect.

Refer to post 50.
Haha, Mild is already on it.

I just realized that I havent seen much for discussion on intake manifolds... they are connected and an extension of the port are they not? or does size flow and velocirty only start at the manifold gasket?

I was at the dyno with Jim and might be able to find the dyno sheet I have the pull written down somewhere. Was he referring to our old race boat with highly ported Dart Iron eagles maybe 308's++? I know that was a 509 and made over 800 but that was with ~12.1 compression and race fuel. That engine was wicked!

They did for sure in the 70's and I believe into the early 80's.

My intakes are welded up and matched to my heads. But my ports are not standard oval or rectangle. Also, a single plane outperforms a dual plane on my engines. I didn't believe it until last summer.

Not sure what I was thinking. The math wouldn't work with his top speed anyway. We had to of been talking about a combination of builds with what I've got going on also.

I had the epoxied heads from Jim before he got all into welding. Lol. Regarding manifolds it was really mind blowing at the time however began to make sense with having a torqer 2 dual plane intake REC port on the raised floored darts and made more power. Not so uncommon anymore but in the late 80's people would thought you were right out to lunch.
