I'm going to post up some before and after results here to highlight some of what we did. Keith Last edited by Dunnuck Racing; 06/13/14 11:21 AM. www.dunnuckracing.com

A Firecore distributor was added to provide spark from the Accel Digital ignition. Running through a 727 with a Turbo Action10" convertor, 4.10 gears and Coltrane, the 3800 pound Satellite ran a best of 12.11 @ Norwalk last fall. Hmmmm, cant get any pictures to load right now.

Scott bought 2" Super Comps planning for the future. We knew they would hurt the torque curve. The convertor stalled to 3800 in his car. 8174978-NCM_0091-1.jpg (279 downloads) Last edited by Dunnuck Racing; 06/13/14 12:43 PM. www.dunnuckracing.com

I probably laughed at that . I told him I could port his heads and build a nice short block, New cam to go with it, better intake, etc. And get a little over 600 on pump gas. www.dunnuckracing.com

Final compression after minor chamber clean up to the heads is 11.2 to one. With the large cam and aluminum heads it will run on e10 93 octane easily. 8175874-NCM_0270-1-1.jpg (251 downloads) www.dunnuckracing.com

The peak horsepower was 649.4. So no, I didn't get what he wanted out of. I could have done the hot oil/ cool coolant deal and easily went past 650, but I ran it like it would be in the car at 170 degree water temp. These pulls were with the Driven brand 10/30 break in oil, and now I have him on Driven 5/20 conventional so I'm sure thats a gain also. First day at the track along with a new 8" convertor he ran a string of low 10.60's with a best mph of 127.2 60' times were really soft, 1.55 range driving it like his old combination. The mph should be good for 10.40 something I figure. Keith www.dunnuckracing.com

That and a couple other things had him at 3610 at Martin. When I gave him the engine I had the timing at 34 total and it made more power at 36. If we get it to 60' we have a little room to play with it yet. www.dunnuckracing.com

The air was decent, mid 70's low humidity, but the barometric pressure was mediocre. Sorry I done have exact information. I had tires blow out on my dually and ended up with my open trailer and small truck. All my tools and equipment was left in my enclosed trailer. Keith www.dunnuckracing.com

I tried loading it at 2500 and that made all the difference in the world.... Now the converter hits so hard we are working on trying to get it to hook again...
