With the car set up with a lower down power number I have been 159 and change at 10.90 a number of times. All out the car has been 168. I wish I could find a good set up to not loose the MPH I do. But the car is not dialable(is that a word)set up that way ,at least for me but it can go 159 at 10.90. One thing for sure in Phoenix my t stop set up was NOT the way to be doing it on that track that weekend. Last S/ST race I ran at Infineon the car was running 153-4 with over 5 seconds in the timer. DA's were -50 to 600' IIRC. Hard to run fast when I am on the stop at 4100 that long. So tell me please what the secrect is. I have watched your car a ton of times trying to figure out that magic set up

Give me a break that Infineon Divisional was my FIRST ever S/ST race. Thought I did ok we are still trying to figure this stuff out for sure.

Cant keep it running that that long, TOUCHE! Jeff you got me there for sure. The again I dont have anywhere near the cubes at 500" that some do. Motor had 228 passes on it when we pulled it out. About 1/2 wide open shifting at 8300, but only going through the traps at 7450(no gear). Had a freak failure for sure. The Roller that was in it went soft, I run a roller cam bearing and one of those bearing surfaces on the cam was flaking. Scored cylinder walls and was wreaking havoc in general. Last time the car was out was on Memorial Day at Infineon with the cam going south I went 11.04 at 152 with timer one at .000 and timer two at 4.87. The next pass was more of the same and the car should have been faster. Did some poking around and decided to just put it away and freshen it up to try and make the infieon race. Well we pulled the motor down then and just now getting it back in the car. I simple freshen up ended up being a reinvention after finding the roller cam had gone soft on one of the bearing journals. So new pistons, to address a longevity issue, this motor was from a heads up small tire car and never really set up for a ton of laps. We added some more material under the pin, new rods, and a new cam, rings and bearings. Hopefully we did not give up to much power with a new piston that is heavier but for longevities sake it is the right thing to do. Biggest issue was the cam, kept me out of the fun all summer. Trying to get/find a core when you run a 55MM cam, ina Big Block Mopar, that has a 4/7 swap AND all 5 journals being 55MM is not easy to do. So we will see what it will run son enough. We seem to think that the piston deal is gonna cost some power but not sure how that will translate to MPH on track. If I can get off the stop sooner it SHOULD go faster maybe, but time will tell.

Can I help if I like to go fast?

Wish I could figure out how to go as fast as that Mustang can, I think I do ok for a 2885lb Super Streeter. Then again maybe I should go back heads up small tire racing. Can always dust that thing off and go run 7's all day long....
