String of 500hp and string of 500 torque, peaking at 6200ish
Yes, small solid roller
Walk in the park. 500 tq is more of a challenge than the 500 horsies but neither should be much trouble at all for something with some effort thrown at it. There are out of the box heads that could get that done. I have a suspicion you are intentionally understating your goals because of the TPI///understandable but dynoed with single 4.//solid roller 379 with ported heads and manifold////570 plus or its broken.
It won't make 570 on the dyno I use. The 385, two weeks ago with a 253/260 and true 91 made 547hp. Which on that dyno was 25+ more than other engines of equal size.

Chad,
Many of the fast Chevy Super Stock cylinder heads have been ported and epoxied into an oval intake port.
The first Heads-Up, Dave Layer, cylinder heads I took a look at in the early 1980's, had oval port heads and the car was a record holder in its class.
Every Super Stock head that I do is oval and raised. That is why I wanted to try it on this.
However these flow way too much air to be this small and oval, IMO.
Do the 2 ports sound different. Does the faster oval sound smoother
I thought the biggest reason you would epoxy the floor and make oval. Is to help the ST handle the higher air speed and not seperate/ back up
I am guessing something along these lines? I have never flowed anything like this. I know there are manufactured elbows with turning veins to help even the flow through the turn. I can see it working well on a boosted application but may have uneven flow on na. I am interested in what you come up with.
