After WAY top long after hurting the block to the B1 engine my son finally got the ole Racetech back to the track with its new to it 600-13 headed deal. Pretty mild engine honestly 13-1 compression nitrous piston and "nitrous" cam, 600-13 head, Brett Miller Ported intake and a 2.200" Braswell carb. Made ok power for being so mild, was not looking to rotate the earth with it. It was a good deal for me used and since I still don't have a block for the B1 deal this will work for now. I bought it and freshened it up with only minor changes, new rods, rings, bearing and pistons coated by Line to Line to make up for some "extra space" in the bores, a new carb and Brett Millers handy work on the intake.
My son was getting his license runs in after letting it lapse due to the two year layoff, form the block ordeal. Never made any full pulls on it but this was the last one of the evening at 1230, and he only stayed in it til 6.0 seconds. Was trying to keep it over 7.50 as he has not gotten a physical yet for his advanced ET license as we didn't think it would run quite so good in such crappy air. LVMS is at 2000' elevation, it was 99.8 degrees, 14% humidity, and the barometer was 27.71 so DA was 5300'+-, and the track was hot and TNT prep. Good but not the best it can be for sure. Anyway this hit was 1.053 60', 4.687 at 147 and went 7.41 166 lifting at 6 seconds. So it certainly shows promise for sure. It was still pig fat as he didn't touch it from when we had the dyno debacle. AFR's were in the 11.2 range. He was short shifting it by 400rpm and the converter is VERY tight falling back 1100+ on the shift. We also have a vacuum leak at the belt drive cam seal so only has 4" of vacuum in high gear. So some promise for sure. I think with the AFR's and upping the shift RPM a bit it will run maybe a high .20 in similar air in Vegas. That run he lifted and would have been a mid .30. So maybe teens or an Oh in the great fall air possibly. But that will have to wait til he gets the physical, already has all the safety stuff. Anyway just wanted to post it up, his lights were all pretty good to after his first hit and nerves.
