Finished up my Engine
Folks, as some of you know I was working on "updating' my Stock LS5 454 earlier this summer after my return from Iraq this Spring.
The updating (Cam and Head change) turned into a complete engine over haul after I got into it and found some cylinder wall wear. Upon tearing down the engine we found a bad throw (crack ) in the crank and we proceeded to bore the motor .060 over. Number 6 and 8 cylinders had casting defects surface that showed up after the bore bar went through and they would would require sleeves so... bought a different block.
After all of that I finally got it together with a nice blueprint and balance. The block was decked and the compression came 9.2 to 1.
SPECS ON THE ENGINE:
454 (.060 over 467 CID)
Edelbrock Aluminum Heads (2.19 / 1.88 valves / 100 cc chambers)
GM Aluminum Winters Intake
Balanced and Blueprinted
New Rods
New SCAT forged Crank
TRW Forged Pistons
Comp Cams XE (505 / 515 lift with 218 / 224 duration @ .050)
Comp Roller Rockers, Push Rods and Lifters
I put in a Dewitts aluminum radiator at the same tiem to help keep it cool. It runs well and I am pleased.
Here are some shots of it going in. I will post more of the car later.
