LS motor can look like that.
Just relocate the coils
No, they are not. The L92 heads (the LS3 heads are the same, but with lighter valves) have the rectangular intake port shape like the LS7 heads, but it's smaller.
You're right, I screwed that one up. Fixed.
That to me is just more attractive with the coil packs where they are.
Definitely a better motor all around.....FI or Carb'd.
Carb'd is cheaper , but not as efficient IMO.
i would turn an ls1 into a 383! LS383
you can always go to LS1tech.com and get info on the motors, and maybe even find people who do the harness mods. quite a few there that can offer help or info.
as for 90k on the motor thats mild range for those, have seen them with 175k with no problems, in stock trim the LS1 is close to 380/400hp, and a few bolt-ons will have it pumped up pretty good, I know a few that are pushing 470 rwhp and still getting an average of 25mpg around town, yet go to the track and lay down mid 10s/ low 11s.
LOL. The LS3 is already a 376, so with a .030 overbore, I guess you're there, or real close.
Can't bore aluminum (sleeved) blocks that much - usually only hone .005 at the most...
The way to make a 383 is to put a 4 inch stroker crank in an LS1 block
Are you sure about that? The sleeves are not made from aluminum and .030 overbore is not much at all. Thats only .015 of metal removed....
I'm posative - correct, the sleeves are not made of aluminum, but they can't be bored in the aluminum blocks - they are too thin. The iron blocks (6.0L) have thick sleeves and can be bored .030, .040, and sometimes .060 (but .060 is not recommended).
If you look at pistons for an LS1, you will only find 3.905 and stock bore is 3.898. For the iron blocks (4.00 bore) you can get the oversizes for boring...
Id do the ls swap for 1500 cant find one that cheap, but would prefer the 6.0 vortech 6000 out of a truck
