No secrets here 12.5 comp and mid 600 lift. The engine peaked at 6500 rpm. Sometimes you just hate to dyno Auto's with no lock up and post numbers as they don't seem very impressive but we are happy as we had a similar NA setup that made a bit more power and ran 9.60's NA Time passing and R&D sure pays off, smaller portvolumes, attention to detail and programming sure make the diff.

Thanks Nick, sounds great I'm building a 408 ironblock just for the track{1/8mile mostly,we don't have a1/4 close by]want to use a big solid roller cam probably around 260 @.050 with .670 lift ,110LDA??tThinking of using ported 5.3,s Jesel shaft rockers 1.8 rr, maybe aluminum con. rods, electric w.pump ,fabricated aluminum intake,not sure on pistons yet maybe Diamond or C .P. What do you suggest? BY THE WAY I LOVE ALL THE WORK I'VE SEEN OR READ ABOUT FROM YOUR SHOP!! Thanks Mark.

Thanks Nick, you must think I might have trouble with the 1.8 Jesel, I will be running some big springs ,I'll lose about.037 lift but I guess that'll be OK,should be about.636 with 1.7's.You think I should run more duration,they have 268, 264, 260, all with the same lift? This is going in a gutted car 2500lbs 4-link rear,. 4.88 gears 4500-5000 stall with a powerglide ,plan to run 2 stage no2 after I get the motor sorted out.probably will see 7500-8000RPM.
