Smog Legal Engine

Ok, I want to either rebuild or replace my 350 TBI in my 1995 Chevy Truck. This is a Cali. truck. What is a good high output 350 or 383 engine that is smog legal to swap in? Don't care too much about using stock computer. If new engine is the route then I will probably use Holleys Pro-Flow fuel injection or Edelbrocks fuel injection. Or, if you think a rebuild is a better way: I was thinking of Edelbrock performer package but I am looking for 400 hp. I don't want to spend more than 2000 to 2500. Just remember: Smog Legal in Cali. I was looking at GM crate engines but none are smog legal.

Re: Smog Legal Engine

This is my plan in one year (after I graduate from college).

1. Build a stroker. 33 cubes is nice for horsepower.
2. Use the Edelbrock multiport conversion manifold.
3. Install a relatively radical CompuCam.
4. Use aluminum heads: Edelbrock and TrickFlow make smog legal heads.
5. Smog legal headers like Mesa, JB, of the such.
6. Custom computer chip from Fastchip to take advantage of the new add-ins.

I will keep the computer control since it allows for ideal AFR, no matter altitude, air density, temperature.

As you can see, I haven't worked out any specific details since I won't have money for a while, but this is the general path I plan on following.

Re: Smog Legal Engine

how can I figure out if all my components when assembled will be Cali. smog legal? Is your truck a TBI? I was origionally planning on edelbrock performer package which is: heads, cam, headers, cat-back, and the Multi-Point injection system. What hp will this produce? I was wanting to use stock block. Maybe replace pistons but I don't want to replace the bottom end. Anyone know of a good high output replacement engine?

Re: Smog Legal Engine

I just put the whole Edelbrock kit (less the Cat back I already had a flowmaster)on my '95 K1500. I don't know the HP it is putting out now but I can tell you it made a huge difference. Even undergeared with 38's I gained a lot of power. In fact, I embarrassed an F150 tonight on my way home from work. Thats what you get for buying a [email protected]**. Anyway I can tell you right know it is not a cheap road to go down but if you have any questions feel free to ask.

Re: Smog Legal Engine

Thanks man, that is the info I was looking for. Did you use the multi point injection or the new intake manifold?

Re: Smog Legal Engine

Buy a Summit catalog and look through it. All of the things I listed previously are 50-state legal. That includes Cal. You can't forget the catalytic converter on the exhaust. It will have to be a single cat in the stock position because that is the letter of the law, but a three inch exhaust with a highflow cat, y-pipe, muffler, and mandrel bends should be able to keep up with your motor.

Yes my truck is TBI.

Re: Smog Legal Engine

Yeah, I have a Summit catalog, thats where I got all the info. on the edelbrock stuff. But, if I install all the edelbrock stuff, and later I add a 50 state legal supercharger, will the edelbrock and the supercharger combined still be smog legal or is it just one or the other? Also, what is a good Cat. for my truck? It's a 3" 2-way right? My truck has no air-injection.

Re: Smog Legal Engine

I used the Multi Port injection. There was a string on here a couple of weeks ago about running a supercharger w/ the Edelbrock kit. Somebody said it was a one or the other type deal. You should try a search and see if it comes up.

Re: Smog Legal Engine

I know about the post. It was mine. I was just wondering if I get both the supercharger and the multi-point w/performer system and get a custom FastChip made that will make both systems work properly together and be smog legal.
