I'm looking to rebuild the engine in my 92 and add some HP. Does anyone have some good info on after market C.A.R.B legal high performance parts?. Any help will be great.

Thanks in advance

First off how much power are you looking for, budget?


Not sure if blowers are around anymore?
Dougs headers makes a nice legal shortie, you can stroke it, small cam (watch the overlap)
AFR makes legal heads for the L98 not sure about LT1;Id keep the stock TB
Youll need a good tune, where are you located

Thanks for the reply.
I don't necessarily have a budget. I just have a concern about passing smog. I also want to make it drivable on the street. Don't need a blower. I've heard of the shorty headers and about the CAM. I'm located in Temecula Ca.

Skip the shorties the stock LT1 manifolds flow enough for what you are doing. I’m in Menifee and have done a number of LT builds for myself and local friends.

If if you have a good running engine I’d do some ported heads from someone like Lloyd Elliot or TPIS. Both of those suppliers have cams that will pass smog as well. Biggest issue will be tune as the 92 still runs a prom set up and is kinda a pita.

Feel free reed to stop by sometime and we can chat I have 3 LT builds going on at the moment one 396 on the stand and two 383 builds that just went to machine shop

The AFR 180 and 195 heads have EO numbers, and are emission legal. The 210 and bigger heads aren't emission legal

Why spend a ton on old heads that still wont keep up with brand new ones that have a lifetime warranty? (If money isnt a big deal)
Shorties will give him a gain...not huge but its there esp with a better breathing/stroked motor. It all adds up

a head in the high 2xx range, simple hotcam ported intake etc can get him high 3xx at the tire and pass smog. Stroke it hes over 4 with plenty of torque just a thought
