I dunno just always wondered i guess, and now that i have a lower lsa cam and want boost it doesnt help my wondering any..

Good to see something somewhat different tho, definitely let us know what you think of it compared to your other cam and boost setups..

I originally started with an 05 crew cab Z71 5.3 truck, went through several setups including; 5.3 with bolt ons and cam, 6.0 heads/cam n2o, 6.0 tvs1900, and 6.0 turbo. Truck ran good, but it was obviously pretty heavy at 5900 lbs. Ran it at the track with the maggie to a 12.87 on 6psi, was maybe a little faster with the turbo at 7-8 psi, but the weight was killing me. So I found a deal on a 00 rcsb 4wd truck that needed a motor. I got it and put a $250 junkyard 5.3 in it for the time being, had an 80e built for it along with a circle-d converter, and put my kbracing tc76 turbo stuff on it. Truck runs high 11's with the stock long block 5.3. During this time, I have been building a 365 (.005" over 6.0) for the truck. Plan on 12 psi street, 17-19 for the occasion track run, and will still be running e85.

Here is the truck when I bought it.


Here is how it looks currently with a new hood, front end, paint, and lowered 2"


Turbo on the 5.3


Pistons, Autotec forged 4.005" bore 4032 pistons with the upgraded rings. Should be around 9.8:1 compression with 317's. Will be running E85 only.


Block prepped and painted, Old Chevy blue, saw it on here once, don't remember where, but I really liked the way it looked.


Installing crank and lubing journals.


Crank all buttoned up.


Pieces of the puzzle I am using. Autotec pistons, scat forged I-beam rods, isky 218 218 112 cam, clevite bearings, arp head studs, ls9 head gaskets, isky valve springs and pushrods. Pistons and rods are quite noticeably lighter than the stock 06 lq4 piston and rod combo.



Bottom end all buttoned up, head studs installed.


Thats where I am at so far, waiting on the rear barbell oil diverter plug, then I can fully close up the bottom end and get started removing the 5.3.
Let me know what you guys think, trying to get it done, broken in and tuned for the car craft summer nationals the weekend of july 22nd, should be done.

That's high 9 sec power down low if the rods cross the line with it That's a raw uncorrected 832HP at 8000' DA out of a stock longblock water spitting LQ4...

I also like how you did the holes in the lower valance for air to the I/C. Looks a little cleaner then my idea of making one long rectangular hole haha.
