Several years ago at an NHRA event in Sears Point, I asked the GM rep about emissions on the ZZ-4 and the Fast-Burn 385 (the ZZ 383 was not out yet). He said both engines would pass the Cal emissions tailpipe test even though they had no EO#. But the fast-Burn 385, and so also the ZZ 383 have Vortec alum heads, so the stock smog equip will not hook up. But the ZZ-4 smog equip does hook up to our L-98's.

So I guess from what I am reading it is okay to still go with the ZZ4?. Is their any other engines out there that would be a direct bolt in maybe better to use in this situation?

TO be honest with you. If you are expecting to run 12s with a ZZ4 and superram..it's not going to happen.
You have have to change out the cam and port those heads for that kind of numbers. You should really opt for the fast burn 385 and the Hot cam (or 219) with 1.6RRs. If you do that with the SR, you will see 12s.
Stock ZZ4 long block and SR, you will NEVER see 12s. That's almost like putting the SR on a stock L98 and running 12s except with the ZZ4 cam.

For a little more dough (1 grand to be exact) you could get the ZZ383. Much better motor than the ZZ4 or the fast burn 385. The heads are too big for a 350 built like that, look at how much torque was lost by swapping out the heads. The ZZ 383 has better heads, better cam, etc, etc, etc. Well worth the money, down the road you will wish that you did. I don't know if you already have the superram but just buy the plenum and runners and buy the base from SDPC and you are good to go.

Yeah, I don't think I should have used NEVER but more like....
"results such as this are not typical".
The original poster should ask how many people on this forum is running 12s with a stock ZZ4.

What was the rest of your combo(tranny, torque converter, tires, etc)? I have a similar setup and would like to get into the 12's.
