I gotta keep it short, lol.
Found an LS1, with 150 shot that ran lean on the dyno. They added a new pump and its had about a bottle and a half ran through it on stock internals (besides a cam with ~40k miles). Should i stay away from the car? I'll be driving it quite a bit.. (but i dont plan on spraying it anymore)

 

tough call, hard to tell. If you have any doubts, run away. There's something out there that's waiting for you.

 

how lean did it run and how much power is it making NA on the dyno.

 

im not sure how lean, but it made 390 to the wheels w/o spray. hasn't been on a dyno with the spray since its ran lean, but it has been sprayed on the track (and probably street too) since then.

 

if its still making good power since then, and they fixed the lean problem theres no reason not to get it

 

If the car is making 390 NA and has no problems (smoking, hard to start, a banging sound) it could be a good deal. 390 HP is a good jump over stock. It is a hard call but if you do not see any of the above it might be a fair deal.

 

yeah, the car made 390 with bolt0-ons and the cam it has in it i think.. but that was before running lean..
when the current owner first bought the car he ran a 12.3, but i dont think it's been on the dyno since the first time..
