Your goals sound like mine. Don't know if I'll get there w/ the 4.8 though.

 

Honestly white I just dont see it happening man. I have all teh mods you do except for the cam plus a big stall and I couldnt crack the 13's. IMO you wont do it N/A now with a shot of nitrous sure. I think with the mods that I have along with lt headers, bbk tb, cam, a nd retune with a 3400 stall and 30" tires instead of 31.5" tires I think I will be tickling the 13's. I doubt I will make it into the 13s N/A also with the mods that I will have. After those mods plus a 100 shot I honestly think I will be running 13.2s or so now you have about a 200 pound weight advantage on me though. You also need to look at your mods and mine I was running a 15.1 without the nitrous so I already have a head start on you. Dropping the buckshot tires will definately help out alot.

 

only big diff. between you and white is the weight difference. rcsb and ecsb... but I think the cam will make up a lot of the difference and maybe a 2800-3200 stall and some sticky tires so you can tack it up all the way on your launch.. i mean its possible... maybe with some serious weight reduction too...

look on ebay for some cheap slicks.. i got mine for $200 and they only had like 3 passes on them w/ no highway miles.

 

Man you disapointed me. I was 15.5 with out the tune, exhaust cats or cam, and I still use the factory airbox. I guess I'm just getting my hopes up with the stall big cam shift kit and heads? Oh well thatnks for being honest I guess we'll see what happens. I may have the spray just in case
BTW check out 12sec5.3 mods. He doesnt have much more than I will.

 

For what its worth i dont think you will see 13's N/A but damn close it just that our trucks are so damn heavy and driveline loss too. Also depends on what kind of heads you are getting and your shift points. If you drop down to 29" tires then I say you have a fighting chance of hitting 13s.

 

May have to try some 26's then

 

Man if I dropped down to 26's I would be pulling a Parish out of the hole. That would be enough IMO though but i would stick to a decent size tire no smalller than a 28" after that you are just going to be spinning too fast.

 

He and I have a very similar setup and the lowest motor time I got was a 13.17. So it is kind of difficult to make an accurate comparison that way. If you get a little larger cam, heads, 3000+ converter, longtubes and a good tune, I could see you getting into the high 13's on motor on a good air day.

 

Well, I'm gettin a 3000 stall (hopefully from you) a set of heads (similar to 12sec5.3) and I cant find any LT's I like that I can afford right now. Hopefully I can get a 13.9, but I guess well see.

 

i'm still trying to get a 13 something on motor. which with the new tranny and 3200 stall i should be there. previous best was 14.4 and that was before the new exhaust and headers i got from bigkid.
