will 2300 stall be enough for this cam?

i don't know about nitrous, but i know of a certain fairmont with a junkyard 5.3 that is seeing 600+ hp with a turbo, over 150 drag runs, dyno pulls, and thousands of street miles, and it's not missing a beat.

Nice combo. However, knowing the price of gasoline, I'd opt for a built
4L60/65 trans for the OD.

The thing is about the l59 engine is the intake flows the same amount as the ls6 intake... it would be a wast of your money to buy one... if your going to buy a new intake i would buy a fast intake......

Not sure on the TB but I'd slap some comp 918 valve springs on it. Spray it all day long with a 100-150 hit with a safe tune.
