I'm actually impressed at the numbers on 10.5:1. Probably could go 11:1 and make 400 all the time. I have a similar combo but roller cam with a little more compression than you and a C4.

I'm using a trick flow cam in mine and it does well. I don't have any complaints.
My car is kinda a long story so I'll keep it brief. During the build I bought some used injectors off someone I didn't know and got burned on one of them, it was cutting out at 10% duty cycle when I had them cleaned. I had it tuned basically on 7 cylinders and didn't know it till it bit me in the rear. Engine put down 402/422.1990 GT

I thought it would make a bit more hp but depending on cam specs it's hard to say. The last 347 i built was afr 185, 10.5:1, comp xe274 cam, victor jr fuel injected lower with an elbow and Accufab 90mm Tb, bbx 1 3/4 long tubes with 2.5 exhaust, 4" induction with a lightining maf it made 420/387 rwhp through a t56.

My car has a t56 also. 4:10 gears. Whenever there's a dyno day at a shop and cooler wheather i will take it and see what it does. At one time with the old tune it did 410/430. But i am happy, it runs really good. Just it hangs around 1200 rpm for a few seconds before it come down to idle at 900 rpm

Did you pick the parts and build this? Where'd you dyno it? I'm out in Crandall, and I have been looking for someone close to help me out. The big heads, intake, and custom cam deal seems to be the way to go now a days. How did you pick Engle for the cam? I'd be thrilled with those numbers on my 90 vert.
