Default stock bottom end lt1 juice?

i have a 97 lt1 formula with about 1xx,xxx miles on it. it has some ported heads and a pretty big cam and it dyno about 420 to the ground through a t56. so my Q is how big and what kind of shot you guys think i could put on it without blowing it up? this is my only car and i cant afford to lose it. thanks for any help.

if you can't afford to loose, don't gamble. Pushing it more will just cause the inevitable to happen sooner... something is gonna give.
100,000 + miles isn't a good starting point.

Shot 100 through my 94 with 100k+.... No problems.

Probably wouldn't get much higher than that.

I ran a 125 dry shot (that came up 175rw on a dyno) for 3 years on a stock bottom end 350 before I eventually cracked a ringland during a normal commute. No damage to anything but the piston, but I wasnt making as much power as you NA at the time, and I didnt care as much if it broke.

I'm with this guy. Its really hard to say -- you're gambling right now with your current setup (no offense) unless you're definately not over-revving it or abusing it.

On the stock shortblock with that many miles, just stay safe with a 75 wet, maybe bump up to a 100 wet for track/dyno days. If it was me, personally I'd hold off until I had the money for a new shortblock -- either way you're driving on borrowed time.

I agree with all the above. If it is your only ride, keep it smallish and go dry.

150 wet shot on stock LT1 with bolt ons, 123k miles, never hurt anything.

i wanted a 150 wet but i just had it installed today and the shop said 100 tops. so thats what its at now. they also pulled 4 degrees of timing and ill be shifting at 6000. the car has really good oil pressure, and makes no noises. i just want as much as i can get SAFELY.

oh and this is c5formula.

link? they must have had other issues bc the cranks will take ALOT more than that.
