so i figured id fill guys in on what to expect from a ls376 535hp gm crate motor. my g8 gt had 154,000 miles on it so i decided to play with this car. i had priced out all the parts and figured in what my time was worth to do a cam swap and a dod delete to my car, after all prices etc come back i decided to look at engine swaps for the extra investment so i wasn't throwing away good parts on a higher milage g8 gt. so i will fill you in on the results after the chassis dyno tune. ordered the Ls376 535 hp engine from gm and a 3000 stall with jba long tube headers and solo cat back exaust. after swapping engines and slipping a convertor on the tranny while engine out. the car has a nice rumble to it when running the car after, all this with a 2 year warranty. I'm very happy with the way i went and how it turned out so far. will post hp and torque from the chassis dyno and final tune. the tuner expects to get 30-40hp over the adververtised hp etc, we will see. think changing motors was easier then stripping engine down in the car to do a cam swap and dod lol. if this thing performs like it sounds it should be a fun car for the summe. will post pics and numbers after the tune and dyno. i will say this was a drop motor and hook wiring back up.
