Been engine shopping (cause I'm pretty sure I "killed" mine before shipping the car from Germany back to the USA). Weight is an issue, as the car is a street/auto-X car, so been looking at aluminum block engine combos. Budget is also a concern (like to keep the grand total under 10K while doing the install myself).

That said, anyone running a TSP 383 combo? Experiences, opinions, power output info appreciated. In short, I hoping to reliably make 500-550RWHP in a daily-driver friendly combo for under 10K that weighs the same as my current LS1.

Also been looking at the SpeedInc 403ci LS2 block with L92 heads/intake.

Thanks for any info or $0.02 on the subject.

http://sdparts.com/details/gm-perfor...parts/19244611 might run a lil over your budget but imo nothing would be cooler than having a 454 lsx under the hood, if you have plans to stay na this would be what i would go with, plus you can do a few cool 454 badges lol

That would be pretty bad-a$$ed... but I'm guessing the total would be more like 14K+ after adding the oil pan, intake, and figuring how to integrate the sensors into the factory gauge cluster (if that can even be done).

Appreciate the suggestion though. It looks sick

I have a TSP 383 shortblock in my car. It's been in there for 4 years now, runs great. Not sure what I am making power wise, but it runs hard and strong. You will be very hard pressed to make 550 at the tires with a 383 though.
