Horsepower limit for out of the box Edelbrock RPM heads

Yow! Great line of posts.

What I have noted is very much the same as you wrote. Not as varied in small displacement engine. Just in SBM engines. What I have noticed (at the risk of repeating myself and NM9,) is a good head and a medium/smallish cam with a good compression ratio will power a car very well from down low to way up top.

I’d link an engine masters video (episode 19 IIRC) but many may have an issue viewing. But in short, these guys did a not so small, small block with a small cam and well ported heads on a 372 engine. The Hyd. roller cam w/224 on the intake had its power band extended a good bit (500+ rpm) and made 470 hp. Same build as the wife’s car though the displacement and how it was set up is a good bit different than the wife’s.030 over 360. There Chevy engine was a big bore/stock stroke combo.
(3.48 X 4.125 Chevy vs the SBM 3.58 X 4.03)




My only road racing experience is a Lemons race in a Honda Accord, but I really don’t think a big port in a low rpm engine is a good combo for that! Lol. You’d better swap in a Hellcat Hemi!!
You competed in the Lemon race?!?! Get out!
That looks like a barrel of fun.

But I have to ask, not that I think your crazy or anything, but did you want to put that Hellcat HEMI in the Honda?

Again, not that I think your crazy but I want pictures to copy the build. Think about!
Run silently down the road, talk trash, stomp the pedal and open up the dumps!!!!

Now how cool would that Honda become?
You could potentially STOMP OUT Demons!
