I haven't looked to much into racing a lsx car so bare with me.
1. What are the limits of using the stock Computer system vs. a BS3/FAST as far as E.T goes?

2. How much of a shot can the stock config. heads hold with out lifting every pass?

3. Who builds the best for the price 402 ls2 ?

 

1 I went 9.5s on a 150 hit with stock ecu ....

2. i hit mine with a 250 a few times and it did not push a drop of water. Tune up is key if you have a good tune up you will be fine.

3) give texas speed a call i use alot of tthere short blocks

 

Only thing I'm worried about is the timing aspect in the event I decide to hit it with 2 kits. Oh and define a few times. Lol I'm looking for longevity I don't want to swap headgaskets every month....

 

How much are u looking to hit it with? with a Good 1/2 head stud and some good gasgets and a good tune up it will be fine. i hit it about 12 times on a 250hit.

 

I got a couple 402 iron blocks out there running 8's on spray,no head gasket issues.

 

I'd like to spray a 200-250 out of the hole then add another 200. The more I read the more I'm leaning towards the carb'd + msd timing box route. From what I've read you can program different stages of timing retard with it. Thanks for the info guys I appreciate it keep it coming.
