Critique this 402 setup Ran into some bad luck with my 427 setup. Found out the darton block was cracked when it got filled up with coolant today 
. Going budget now, and my shop is going to get me a LS2 block w/ a new set of pistons. Haven't been keeping up with 402's, so tell me what you think of the h/c setup with the parts I already have, streetability, power, ect.
TEA stage 3 6.0L heads, 2.10/1.60 peak flow 343/268 @ .600 (graph didn't go higher)
port matched FAST 90mm/NW TB
244/250 .635/.625 112

Sorry about the 427
I don't know too much about LS2's, but I would LOVE something like that in my car!
I don't think the streetability will be great unless you have a REALLY good tune as that is a big cam.

i'm no cam specialits by any means, but i would think that cam is a forced induction cam - are you supercharged or turbo'd?
the reason i ask (and again, i'm almost cam illiterate, but have been reading a bit about them) is that boosted cams are usually off balanced on intake and exhaust in both duration and lift - i just don't know which F/I type tips the scales in which direction.

I have a 402 and I am in the process of switching to a solid roller but I will fill you in on the hyd cam I was running. It was a 248/250 610/612 on a 113 LSA and the engine is NA. It isn't my daily driver but I could of very easily of daily drove this setup. I am running AFR 225 heads with the Fast 90 Intake.

Well I would go with a set of big E.T heads or AFR 225's. I have a 258/262 on a 110 and I drive it everywhere, not daily mind you but everywhere. As for a intake if your more into drag racing I would get the Vic jr efi intake.

11 Bravo - Sorry to hear about your recent misfortune. Even though the LS2 402 is considered a "budget" buildup compared to the 427, it will absolutely scream if built with properly matched components. The parts you have should work great. I believe speedracer5532 was one of the first LS2 402's to dyno and put out 500rwhp if I remember correctly.

Togo- a F/I cam will usually have more intake than exhaust such as a 242/236 and will usually have a wide lsa such as a 114 through 118

The block is only part of it lol. Now, I am actually leaning toward a truck block, only because of the price. I'll make a decision later today before I order.

As long as don't have to fly cut the pistons I might have it running again the weekend of the 18th but most likely the weekend of the 25th. I can't wait to get it running again.
