and about the weight savings, almost all of us over here are 4500 lbs.+ who gives a **** about 65lbs.

 

Lemme toss a small wrench into the discussion. Speaking from a displacement perspective, there's enough meat on the 5.3 to punch it out to the much revered 5.7(346 ci). So upon a rebuild everything's there to work with. Infact that's my plan- when the time comes to drill it out .060", yes I know it won't be the 5.7 sought after but there will be enough meat for another rebuild after that............

 

i gotta ask, where you gonna get .060 pistons for a 5.3?

 

gotta be custom

 

Even more reason to keep weight down, and the aluminum block offers better heat dissipation and the cool factor
I plan on doing a forged alum block LS1 to keep the mp112 in it's efficiency range.

 

Guess I spoke without thinkin'. I was under the impression that the standard overboars were .030, .040 and .060. Like I said in another forum that I was still in the L98 era, circa 1990. I still marvel at these LSx units........

 

the smallest off-shelf bore available is the stock ls1 bore afaik, the 4.8/5.3 bore just doesnt have the aftermarket support of the larger engines

 

btw, i wasn't trying to be an ***, just figured i'd make you think alittle and keep you on your toes

 

check out the new sig. yeah, i'm hardcore haha

 

Awww, geee- I'm gonna hafta rethink my whole Master Plan................
