ive been searching around, trying to find good setups. and havent found exactly what im looking for..like the title says..but im trying to do it without forced induction. i have the stuff in my signature and plan on ordering 4.10's and true trac next. then on to power making parts..but what? i was thinking stage 2.5 heads and a good cam? i seen a member running 12.20's with basically the same setup as me with the 2.5 heads and a good cam. whats everyones take??

 

What do you run now?

 

6L swap with heads and cam will get you consistent mid 12s, then add a decent shot for 11s. Trust me its gonna be harder than you think to get low 12s with a 5.3, do the 6L swap before you waist alot of time and money..

 

Agreed ^^ My buddy did a 6.0 swap with thunder racing classic cam, cut 317's, converter and shift kit with 373's and ran 12.32 in a rcsb with 20's

 

well 6.0 swap isnt going to happen yet..but theres a future for that..but for now. im going to beat up on the perfictly good 5.3 that in the truck now..so low 12's on a 5.3 isnt goin to happen N/A..so what could i run with heads/cam and bolt on's?

 

never ran the truck..not too sure what it does yet.

 

There have been just a select few who have managed low 12s with N/A 5.3, but those were setups that were combined perfectly and those runs were perfect. Its something most people wont be able to reproduce.

That being said, a cammed/stalled/bolt on 5.3 single cab normally runs 13.1-13.5, but a large majority on PT still only manage 13.5-14.0s with the same setup.

H/C and all the bolt ons, you SHOULD run 12.6-12.90s, but again, plenty of people can put together the correct combo and would still only run 13.0-13.5 with heads and cam. Those numbers would be with slicks, good traction, nice weather, low DA etc. etc.

 

Also depends on how much cam and converter you can handle also.

You can toss in a 4400 converter and nice big cam and have a real beast that runs 12.0xs in awesome weather.

 

I ran a 12.4 @105 on 5.3 constantly h/c/i with a 180k motor lol ....have a friend that ran a 11.9 on his 5.3 set up and another a 12.01 also 5.3 h/c/i....

 

You are kind of leading this guy on, you know those set ups were a bit more radical than most people on here want to put on their trucks.

PLUS, the DA down there at nighttime when you guys run is WAY better than most of these guys even understand. There is probably .3-.5 tenths just in the awesome weather alone.

What kind of converter and cams were in those trucks? 4.56s or 4.10s? What kind of heads? Were those on Bogarts also?
