Building an LT1, suggestions?
Hey all--
I have been kicking around the idea of building a 396 LT1 out of my stock 1995 motor. I want a full-out motor with the ability to handle more than a small dose of nitrous (150 or so). I want to spend money where it needs to be spent, but I don't want to buy stuff I don't need. Here is what I was thinking, but feel free to add suggestions:
396, 4-bolt main
Ported LT1 intake and heads
52 mm TB
Cam??? suggestions?
all forged rotating assembly
5.85 rods
I will be mating the motor ultimately to a 6-speed and adding 4.11 or 4.56 gears. I am looking for mid-3 second 0-60 times, and 10's in the 1/4 when on the juice. Any other suggestions? TIA,

Your request is pretty general.
10 second quarter won't be easy. There are several LT1's in the 10's on this board, but in C4's. I think your C3 is slightly heavier...so more power required.
Is it going to be streetable? Blower? How much nitrous is your plan?
The LT1 is very similar to the older style small blocks so that is a plus. You may want to start with aftermarket cylinder heads though...
Not sure what you are wanting...

If you want to go to a 401 you can do it naturally aspirated.

Not too fimilar with LT1 engines, but if you want to spend money where it counts, get some good flowing heads. Also, the more I read, the more important a high quench design seems for the "ulitmate" engine. Do your homework up front.
