Project $50 LS1
I have hinted around about my build on some threads, but I thought I would make an offical post.
I bought a LS1 short block from a '99 trans am earlier this year for $200 wanting to do a stock rebuild. It had dropped a valve on top of the #1 piston, but just enough to leave marks on the piston. I found a good piston to swap it out the bad piston with, and then found a buddy with a set of good '03 vette LS1 pistons and rods to swap with him for my 99 pistons and rods. So, with the vette pistons, I was ready for a stock build.......but what fun is that? After Thinking about it, I decided to forge it!
I sold the vette pistons and rods for $150, and took the $50 block and crank to Lenmar motorsports in Mansfield Texas for them to bore, hone, line bore, clean, balance, oil clearance, and build the short block. Rings are gapped for 200-250 shot, and 20 psi down the road. yes, one day it will be turbo. I still need to build my trans, and get the TBSS intake ported after the swap.
Shooting for low 12's to high 11's n/a, 10's on 100-150 shot, and 9's on turbo/heads/cam same short block later down the road.
mod list is:
LS1 block and crank
JE flat top pistons -2cc 3.905" bore
Callies H-beam rods arp 2000 bolts 6.125"
Clevite h series bearings
Durabond cam bearings
Akerly and childs extreame rings with HTD moly top ring
Rollmaster double chain
ported Melling oil pump with high pressure spring
ARP main studs, head bolts, and cam bolts
LS7 lifters
LS2 lifter trays
Comp 7.350 PR's
all other GM gaskets
Frankenstien Race Heads
799 casting
Hand PnP
milled .020"
60cc chamber
6 angle valve job
2.04/1.57 Ferrea valves
Frankenstien custom dual springs w/Ti retainers
.060" Cometic head gaskets
Comp cams LS1 retro fit trunion upgraded rockers
Frankenstein Race Heads custom camshaft
232/238 .600/.600 110+4
Bullet Cams billet core, custom designed lobes
Power adder for now....
thanks....
