Alright i have decided that i want to go for the N/A record for an Extended cab 5.3L. I know i am insane but i want to run 12's all day without Nitrous. so here is my current game plan.

WCCH Milled Heads
Cam
Headers
SSR Intake
Custom Air Intake

What do ya'll think??

 

I think that you are not insane and have a very good shot at oblaining your goal. Good Luck

 

thanks man. i already have the tranny tied down and the rear soon. i havent been to the track for a baseline yet.

 

I think you'll need that roll pan to lose a little weight. I don't really know but good luck with your goal!

 

You wont be running a 5.3 if you go with forged pistons, they only make forged pistons in 3.902(will make your engine a 347 or 5.7L) or bigger for the ls engines and you will need 6.125 rods unless you go with heavy diamond pistons, you got alot of research to do buddy

 

oh **** forgot about that little detail. alright no forged pistons.

And man i really really want that roll pan. If you still have it in a week than consider it sold.

 

Custom made pistons FTW

 

Good point on the pistions, I over looked that.

 

yeah well those are expensive as ****. and my plan is to go 454 on an LSX block when i hit the record.

That being said, what the hell is the complete N/A 5.3L Record. Not just extended cabs

 

Thats not a fun route(expensive), Ive done it twice and hopefully this is the last time

RCSB N/A 5.3=12.48
ECSB N/A 5.3=13.2s if I remember right

A fat cam, good heads(look up WCCH), high stall and some gear along with full bolt ons and good weather will get you into the 12.8 range IMO pretty easily maybe even faster. AP is hitting 12.5s with his cammed LQ9 you will have better heads then him and better intake so I dont see why you could match him assuming you run a fat stall down low to help out with the tq deficit you have over his 6.0

Just thinking out loud...
