i want to do a similar setup too. right now im looking for heads that i can throw on my 5.3 but later put on a 6.0? any suggestions? ive searched alot but not really sure about what to get since i plan on the bigger engine later. ls6's or 5.3s? def staying na. hopefully i can find an lq9 but if not then i could mill the heads to raise compression on the lq4

 

One thing I suggest you consider is getting a cam custom ground to help take full advantage of the heads. That's the one thing I may change with my truck in the near future.

That engine setup is enough to get a truck in the 11's, just depends on all the other components like weight and 60' time.

 

Nice runs there and a dang nice truck. So a no on that custom spec cam?

 

i still want a tune from you

 

its an rcsb silverado...i wana keep the stock weight to as much as possible..n drive it everyday hi 11s or low 12's but i really want 11's...if its the last thing i do

 

With 4.56s and a 4000 converter, maybe. You'll need a low 1.7 or 1.6 60'.

 

you need to PM Skeet if you want true advice on a streetable 11 sec truck. he runs 10.8s on nitrous and like 11.9s on motor or faster im not sure. if your gonna take the time and work on LS6 heads why not just go with some p&p'ed LS3 heads? same cost im sure and the LS3s flow better than a LS6 last time i checked.

you want 11s do a motor/spec'd cam/3800+ converter/4:56-4:88s/built tranny good luck though. i would like to try a set of 4:56s just to see if i can gain mph...prolly not since its a cam only truck.

 

I think the fastest I have seen skeet run N/A was a 11.38. I may be wrong though.


Nice numbers Truckshop. Are you on the stock converter? I did not see anyhthing in your sig and you mentioned you do not have enough stall.

 

he had yank when it was dynoed
he now has a performabuilt 3400 or 3600 billet converter

 

he had a Yank TT3000 and now he is running a PB Billet 10.5" 3400 converter and locks it with no problems.

i never seen skeets N/A passes
