Default new truck?

I'm looking at a 1994 dodge 2500 4x4. its a nice truck (not that i need another one) but i do have one concern about it. it has 300 horse injectors in it, and a fass fuel system, with a stock turbo. doesnt have head studs either. it seems like the kid just wanted to blow a bunch of black smoke but could that potentially have put damage to the motor pumping that much fuel with a stock turbo?

those injectors are small. 5x12 injectors are 370hp injectors. he most likely has a set of 300hp engine injectors in the truck not 300hp over.

similar to these.

if it starts right up and has good oil pressure there isnt much we could tell you with out scaring you away from it .... most likley he hasnt had it timed up high enough to damage anything ... but then again thats just speculation .... if it runs good and sounds healthy go for it ... if it sounds like sh^& than walk away ... either way if the price is right ... make a good project if you have a decent budget .... my $.02

ok well im goin to look at it and possibly buy it this weekend. and i know that this has probably been gone over several times but i have a set of 35/12.50 mud grapplers that will fit the rims on it. it looks like it might have a leveling kit on it but im not 100% sure. what im getting at is will 35s fit a 2nd gen 2500 sitting stock or with a leveling kit? I expect them to possibly rub when i turn real hard but id like to use these 35s if i can

yeah leveling kit or just go springs .... springs ride better also ... many have given me this advise

yeah a leveling kit or leveling springs which would ride better ... might change alignment but not sure ... I have 2wd so not sure on 4x4

Ok well it looks like it has a leveling kit but ill make sure. and one thing that i was curious about today. can you get a posi trac for these? im thinkin of maybe making this truck a drag truck eventually and would like to put a posi trac in it unless the limited slip in these is good. i just dont wanna burn one tire and not the other haha

the LSD in the 70 & 80 is a good unit ... just need to make sure your running LSD compatiable fluids ... even royal purple .. I run additive , if not it has a tennondcy to shudder a bit ...

know guys pushing 800+hp through a stock LSD .. well maybe the carier and after market clutches but you know what i mean
