My first run was my only good one. Second pass i made my stock posi really mad during my burnout. Run was on 28 degrees and 91 pump gas. Got there to late to grab some 108 unleaded. Pretty happy with that for my first 1/4 run.

60' 1.64
330' 4.77
1/8 7.38
MPH 93.98
1000' 9.58
MPH 107.42
1/4 11.56
MPH 117.96

Good times!! I'm a little surprised that your NA and nitrous 60ft times aren't a little better though with a 4k converter.

Nice times. Yer 1/8 mph seem a little low though dont they for those times? Maybe im just used to lookin at FI mph. What brand converter you running? I bet yer loosing some mph through the converter. You runnin with it locked up? I cant wait for the heat to die down here and get some new times, although I dont know if I want to spray it again. Stock crank on 10psi + spray may = disaster again. I love to see ppl push the limits of the stock bottom. Living on the edge. Looks like you must've done a pretty good job porting the stockers for a 12.56 NA. Good job!

Thanks! I only got one run in before the rear end got really mad at me. I need that solid crush sleeve that you have. lol And i forgot to record my datalog on that run too. I'm pretty sure it was picking up to knock retard off the line.

As for the converter its from performabuilt his trans and converter. And i am not locking it up at WOT Frank doesn't recommend it. I like pushing the limits of the stock bottom end. And i guess i did an ok job on the heads. It was my first time porting spent about 2 months on them. I have still got the stock valves in them as well. I was thinking about pulling them this winter and putting in some 2.00/1.56's

Thanks for all the good words. Sounds like you have a nice car was well, i say spray it!

I was thinking the same thing, the converter seems alittle on the tight side. It has a 2.1 STR it will only brake stall to about 2800.

I have no experience whith that brand of converter. It seems to me though, your giving up a couple of tenths with it being that tight.

I think i am too, maybe i'll send it off over the winter and have changed. But i did find out last night that i was running alittle lean on motor. 13.3 to 13.8 at the high RPM's I just happen to recalibrate my wideband yesterday and went out to check and sure enough.
