the more i think about it, the engine is not happy. with 12.5:1 compression, 660 lift roller, 4'' stroke, 320 CFM heads.... this car should be running 9.90's.

wondering if the cam was degreed? what's the timing at?

i still think it needs a different converter to wake the engine up, it's not performing the way it should.

if you have a 727, switch to a 904 as most people say 2-3 tenths faster with a 904. i've never compared the 2 back to back but that's what i have heard.

Previous owner says cam was installed 4 degrees advanced, so I'd assume it was. Timing was at 34 degrees. I will degree the new cam in and new converter will be coming as well. I don't think the engine was happy either. This is why I did a leak down test on the cylinders and found 4 exhaust valves leaking to where I could hear it and feel it. Piston rings are find. Heads are getting redone, I'll install/degree in a new cam, new converter, and probably do something different with the exhaust, since it had full exhaust with tailpipes. My ultimate goal is to get in the 9.90's, but if it goes 10.20's id be happy.
