It sounds like you want low rpm power. I got 369hp @ 4500 and 466tq @ 3500. That was with the cam at 110. When i advanced it hp and tq went down. That sounds like a lot of compression for such a small cam and iron heads. I would back it down to 9.5 If you havent got them yet. everything else matches pretty well.

I used http://www.virtualengine2000.com and get pretty close to the same. It would move around a little depending upon timing, porting level, spacer height, electrical or mechanical fuel pump,...

Thank you to both of you guys.

Yes indeed I rather like having the power a lower revs. and what it has is more than I can handle!

Just as an additionnal note the heads are aluminium and the engine is built and actually fitted into the car...there is virtually no need to downshift ,while in fifth....I would hit 90 from 60 in a very short time..a bit scary to me..

Thanks again,
Ronald.
