Re: dyno
 The car has cams....split duration 225/236 415 425.....exhaust 222 415; heads are ported not to the extent of Petes.....the next build will be bigger with a 368 and cams.... The heads were mildedly ported, I opened them up more, but they were already siamesed about 3/4 inch into the head, thus the siamese intake to match Car has yet to be tuned and is running a 2.5 Corsa with the resonator.....still has the stock TB. So there is still som power to left to find

Re: dyno
I will let the experts chime in, but based upon the wavey graph over 6K I wonder if I am either over or under fueled????

Re: dyno
Hog, I know, I was just having a laugh.
Funny thing is, I sold my Flying Scot 19' sailboat, trailer over the weekend to a guy from Tenn. who is in route to come pick it up Wed. His only stipulation in discussion is that I take him for a ride in my 1991 ZR-1 since he's lusted for one forever. As part of the sale I'll be happy to do so. Any excuse to run it through the gears a little! Lance....probably for me if I were going to adjust the power it would be a good first step to get tubed headers, open up the exhaust more than the borlas do and think seriously about porting and relieving...but, that costs money and I can't do it myself so I'll just be happy with the mid 400's in crank hp I have...can't run it hard enough locally anyway to use all of that much less 500 to 600 crank hp. Great engine that churned out 441 to the rear wheels.. Lance
