LS# verus LS7

[214Chevy]

I say LS7, 427. I'm going LS7, 427 myself with a wet sump. And $13k for diesel rotating assembly...that'll be a negative for me. May be a cool engine, but I'll pass. Lol!

FWIW
~20k will buy used dmax, rebuild (non 427 stroker kit), install and have 1000-1200hp with supporting fuel and air.
~7k can do a repower and be around 650-700

Go wet sump LS7 and get yourself that 427 you've always wanted.

Marcus wished he "only" had 20k in his engine.
Comparing diesel torque numbers to LSX torque numbers is foolish. And those guys making those kind of HORSEPOWER numbers, Not TORQUE numbers, have pulled out a second mortgage on their farms. The supporting systems to make that happen is BIG MONEY, but I guess an 8 second diesel is cool...

RBuhr69, if money isn't a determining factor for you in this hand, I'd easily go with the LS7, no question. The Mast guys are the real deal. Damon has helped me out a ton, and they always go out of their way for you.

is it cheap..... NO.. none of this stuff is "cheap"..
1000hp diesel is darn near a you need A, B, C parts and a good tuner. engine, turbo, fuel parts can be had for ~20k labor not included

beating up on gas engines like audi does at the leman with a diesel is definitely cool and different..

i'd side with the LS7 over the LSx



got to pay to play right?

There is something special about a 427 for me. Katech converted my LS7 to wet sump, and added their Torquer 110 cam and CNC heads, dyno'd at 610hp, 570 ft lb. But people talk about the 'LS7 tax'...and it is real. Got to pay to play.

If boosting is in your future, then an iron 427 is the way to go. The weak link of an ls7 is the cylinder wall/ block support gets thinner, due to the larger bore size. I would not boost a stock GM ls7 block, but I'm not sure the OP wants to boost this engine.
Some of the early ls7's had valve issues, but that's not an issue with the mast black label heads.
