That car had a 305 or 307 in it originally. The 307 you can't do much with but the 305 you can do quite a bit with. A 350 with the center bolt cylinder heads would be a better engine then that and a lot stronger and more hp. LT-1 wasn't that great when it came out, didn't take much for them to go boom! And the parts ugh so damn expensive just to do a cap and rotor change compared to the LS1 when it came out.
