horse power rating on stock LT1

[cam69]

does anybody know the HP of an LT1, and max HP it can handle stock before hurting something.

N/A or forced industion? I used to run a 8# blower on my 94 LT1 making 415 rwhp and never blew it up, but I'd say that was alot for the stock bottom end. Weakest link were the stock pistons which would blow up with too much boost or N20, also opti's were a weak point. The 95+ had a vented unit which was supposed to be a better design.

93-95 F-body LT1's were 275 hp
96-97 F-body LT1's were 285 hp
96-97 Ram Air/SS LT1's were 305 hp
92-96 Vette LT1's were 300 hp
96 LT4's were 330 hp

asking becuse i have a new LT1 that was given to me today,and was wondering if it was worth the effert to install in my 69 convertible with a turbo setup.im not planing on drag racing or dogging the car.i just want to cruse it and the setup to look nice under the hood.thanks on the info ,would like to know your opinion.

I woudn't twin turbo the stock LT1 bottom end, it won't last very long, unless it's running low boost (6 psi) You can get good power from it NA if you install a good set of heads, cam and run a coil per cyl. setup like the LS1. Plus you'll need a good tune.

You don't need the coil per cylinder stuff,The new MSD opti solved all the opti problems,A stock LT1 bottemend is good to about 450/ 475 hp.There good engines,I have stroked Lt1 in my 94 Z and it makes good power.
