Edelbrock Heads for 318

If the longer stroke motor stays together at super high rpm's like a short stroke motor can, then yes it make more power. But you are talking big $ and thats only posslable now cause of the high tech stuff avaiable now.
In a apple to apple, I really don't exactly see it that way. You don't need hi dollor stuff, just a real good machinest. Over the top rpm like the trucks or a good race ride, yea...it would be best to pay the piper. Even years past, to get rpm up high, you needed to spend. So, nothing has really changed. Just the parts have gotten better.
Those NASCAR 9-1 motors would not be good on the street, you look like a freak idling at 3500 at the stop light. The motor needs high compression to idle low with a big heads and camshaft.
It's more so the cams fault more than anything when it comes to idle and quality thereof.
The larger solid rollers with a very low centerline and huhge overlap cause crappy idles. I don't know what those trucks idled at, but in all actuality, they could be street driven. Seriously dont see a 3500 idle.

Is there a NASCAR guy in the house that would know what these things idled at?
The truck series engines.

He he he, our little world. I hear ya there. No matter whats doing, just build a solid bottom and the rest is cake. (May not be cheap......but no good Hooker is.)
Oh, by the way, I do look like a freak, LOL, just playin. :wav:
