long story short, the junkyard 5.3 in my truck lost oil pressure. after no luck finding another reasonably priced junyard engine, I called thompson motorsports and ordered one of their iron 5.7s with forged pistons and rods.

Goals for this build... its just a reliable daily driver. something to have fun with. and i use it to pull a lowboy trailer with camping gear, dirtbikes, and quads. I would be happy if the truck makes 500+ on straight pump 93. eventually it will get meth and a bigger turbo. 600+ would be plain bad ***.

Specs:

5.3 block
3.908 diamomd pistons -10cc
tms rings
4340 scat i beam rods
stock crank
pac 1218 valve springs with .015 shims
BTR pushrods
LS7 lifters
212/218 563/563 113+2 cam from BTR
10:1 compression with my current 862 heads
trick stage stage 2 turbo kit with magnum t70 .70ar

I would like to give a huge thanks in advance to Kasey(06tx4.8) for helping me out with the swap since im in the middle of buying a new house and my garage is all packed up, and to wheatley for tuning this thing when its up and running

 

Update: the engine is ready, so i will be picking it up friday. Should be up and running sunday or monday. I will try to get kasey to send me as many pics as he can and i will post them as i get them

 

Tuned in for results! Sounds like a fun DD.

 

How much boost are you planning to run?

 

I need to get get a new boost controller. Mine **** the bed, so im running on the wastegate spring. Makes 10-11 psi on the wastegate spring now. Im not sure how much boost it will make with the added displacement. I would like to see 500 to the wheels on straight 93, so however much boost it takes to get there.

 

That's my goal. 500 for normal driving and 600 for playing. I'll be giving it 93 and 100% meth injection. Hoping to get close to the 600 mark at 15 psi but we will see. Not really worried about the numbers to much it's just a goal that I would like to meet.

 

no problem bud. motor will be dropped in first thing in the morning. new motor is all put together ready to go!!

 

 

Same motor as Foose04 is running, should be a strong piece!

 

Yessir! I hope it is!
