Ok thanks blk/slvr just wondering what to expect before i get there. So if i go ahead with a 3600 stall prob looking around mid to low 12's?

Time is kinda slow if you have factory 3.23s

Right on par if you have factory 2.73s

I had an 01 Z28 with 2.73s and it ran 13.8 @ 102 stock. Added 3.23s, slicks, a stall and a tune and it went 12.70 @ 107.

Ok thanks mike, Also that was first time ever in an auto so i could probaly do a little better with some practice. Maybe

I'd consider a tune after the bolt-ons you're doing to take full advantage of the new power. Car should be in the low 13s...

Yeah i was thinkin that but then i figured i would wait until after headers but since you say it would be a good idea i prolly will go ahead and do it, thanks

Also like i said first time in auto and all i was doing was foot off gas then tromp. Do you guys in autos hold brake and get the rpms up to about 1500 then release? thanks again

W/ the stock converter yes but w/ a stall no.

I footbrake mine to about 900-1000 rpm and roll into the gas on street rubber. Got me a best of 2.00 60 foot time on the stock Goodyear GSCs.

LOL, I was talking to the OP but I will help you out too. After every time you go to the dragstrip, check out dragtimes.com and click on "tools" and then "density altitude calculator". Use the menu bar to find your dragstrip and the date you ran to get the actual DA for the particualr time of day that you ran. Plug in your 1/4 mile ET and mph and it will convert it to corrected sea level numbers. For your 13.86 @ 103 I just picked 5.54pm (no idea what time of day you ran) and it was 70 degrees with 29.89 bp and 53% humidity. The DA on that run would have been 932 feet (0 is sea level). Your run would have been this with sea level air:

Write that onto the bottom of your timeslip.

The usefullness of this tool is incredible. You might do a particular change to your car that you think will help you out, but the air isn't there that day and your car runs the same. So you go home discouraged but in actuality you picked up 10hp. The DA calculator will show you that your car would have run better.

An example would be for your car that you go and add an electric water pump and an underdrive pulley. You take your car to the same track and you run an identical 13.86 @ 103. You are confused as to why, but when you check the weather, you see that it is 78 degrees, with low pressure and 85% humidity. The calculator will show that you would have ran a 13.6ish, so you know that you did a change for the better, compared to your 13.86 you ran on the 29th.

I have my idle set to 750 and just mash it from the idle. I have a best 60 of 1.879 with bfg DR's in cold weather. I usually spin a little if I brake and use
any power.Oh stock stall!
