Re: Need Advice On A lsx Engine
Depends on the price you can get it for. You can pick up aluminum 317s for next to nothing, and the rear crank flange isn't really an issue either.

Re: Need Advice On A lsx Engine
I would definitely get an lq4. lots of the parts are swappable. You can toss all of these on there and end up with a pretty sweet engine on the cheap
ls2 throttlebody l92/ls6 heads ls3/l76 intake (FAST is too expensive for me) lq9 pistons if you are staying NA

Re: Need Advice On A lsx Engine
99's also had issues with the wiring, in terms of pcm compatability. If everything is together, and a good price then its worth it, otherwise there is ALWAYS another one.

A 4L80E in a 1/2 ton truck with a stock engine is way overkill. If the internet had its way.....Everything would have a 4L80E in it
