I'm just now learning how to paste and copy  youtube,  type in  'racethis'  all mine is for 2013 races some of the races are long. Speaking of Cleveland I sold the engine out of my superstreet car to a guy at jet express 67 or 68 mustang. It was a small block yates, ran low 8's no nitrous.

engine was put together in 2007 but never driven until spring 2012 about 800 street miles. I didn't know it was 9.6 to one compression until 3 weeks ago. I got my stroker kit from AW brown, performance crankshaft in Michigan.

thanks bud for replying back so fast! like someone else has said, if you added more comp to that motor and loose some weight like 2900-3000lb it will get you the 2-4 tenths you are looking for!Shocked

rebuilt the engine this past winter , bumped the compression up to 13.6 . used one of Lem Evens cams and a Steve Johnson port kits .. Was trying to break in the engine without nos ,spinning real bad , So the next week was power hour but I won that race, only used the plate on last pass because the guy I was running broke last round .300 on plate 138 in 1/8 153 1/4 The next week tried the port as a second stage 300 at about 100 mph it came in and lifted the front . But that was short lived, burnt seven plugs and didn't know about the seven melted pistons till the next pass I switched back to the plate and went 8.93 156 blew the oil ring off one piston blew the top off three . The second stage had no fuel. But all is good now bored to 4.440 diamond nos pistons ,reline bored the block 8 exhaust valves, one intake. I just got the short block together tonight. finish it up tomorrow. I hope to be burning rubber Monday and racing Thursday good luck with yours

When you say the second stage had no fuel... Do you mean NO fuel, or just not enough fuel jet in the tune?

Yea, I never ran mine above 8800...  Very Happy

Yep, a man's got to know his limits.  I kept the 552 below 7200.
