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.

hey v-twin how long have you been running that scat crank in that motor?

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! 

hey v-twin hows it going? are you still running that same motor with the scat cast crank in there! about to take my 4.500 scat cast steel crank and eagle 6.7 rods je pistons to get balanced. how many slugs did it take to get balanced? going to run it the way it is. blocks good to about 800-1000hp crank 850-900hp so what the hell!  

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?

yes "o" no fuel going to hook everything up Monday and test the intake in a big pan and see if I can trace the problem. I flowed the nx plate through the solenoids no problem there. will see Monday

hey v-twin do you still have the cast steel crank in there? I love your build! that thing is flying! got the 4.500 scat 9000 balanced with the 6.700 rods and je pistons ready to put together! give me a call will love to talk to you about your combo! ask for tim (216) 754-0938   

yes 4.300 cast

Yea, I never ran mine above 8800...

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