Default need help

So I own a 79' corvette with the l48 small block I want to rebuild it for a little more horse power then turbocharged it...but the catch is I need it to be C.A.R.B. complient. If there is any help or a parts list that some one can offer to make this happen please let me know.

Crane sells a number of smog legal cams. Plenty of heads; AFR has them in 180 and 195 in various configurations. Stock intake manifold is good, you can do an Edelbrock 3701 if you really want to, however I doubt there's much difference between that and stock. Hedman has a few different legal headers, part numbers vary depending on whether you have AIR or not. I'm running 68301-6 on mine.

There are also a number of smog legal heads.

How much cash are you going to put into this build?

I don't know of *any* legal forced induction setups for our cars.

Where are you at in CA?

I see quite a few CARB certified superchargers, but only for fuel injected engines.

Edlebrock has several smog legal items for your car.

Hey thanks for the input and yes I do live in california, with that would it be easier for me to convert to fuel injected to do this set up? And use a supercharger?

Generally, the CARB exempts parts for specific models. There is nothing I know of (supercharger, turbocharger) that is legal for a 76-82 Corvette.

You would have to find a setup that was legal for another car, do an engine swap (a specific BAR process) to that engine and install the exempted supercharger kit. IE, there are plenty of legal superchargers for C5s, 6s and 7s, so you could "swap" an LS1/2/3/7, LT1, etc into the car and install the corresponding kit. You'd probably want to base the engine swap on a car that has an exempt supercharger that will fit decently under your hood. I couldn't tell you what that is.

The BAR engine swap requires all you to use the entire emissions configuration off the donor car (cat configuration, EVAP, O2 sensors in the right spots, MAP, MAF, etc).

It'll be very expensive and a lot of work to do right. But you can do it.

I was asking what section of CA specifically w/ my earlier Q, if you're nearby (South Bay) I could take you for a ride in the 78 so you can see what a fairly "high-effort" smog legal build feels like.

I'm located in San Diego and I've considered an e-rod setup from chevy, it seem that taking that route would be my easiest route but like you said pricey. Also im doing all the work myself and im not a mechanic by any stretch of the word so everything i do is a learning experience. So doing an engine swap would be hard since I wouldn't know exactly everything I would need to take from the donor.

The LSA E-Rod kit would probably be the "one stop" way to get a fuel injected, supercharged setup and you'd probably spend nearly as much, if not more, trying to source everything legally.

Do an internet search for 19257456 (GM Part number). $13k, but you'd probably be about $6k into a legal supercharger right off the bat, before you got the engine, wiring, etc.

What is your goal as far as budget and power?

the only reason i was going to turbo was because i wasnt going to get the horsepower i wanted after i rebuilt the motor so i was gonna rebuild then boost. but i can get an e-rod ls3 with 430hp which is all i really want for around 8k plus whatever it takes to install i was just wondering if there was a cheaper option like parting a donor or if the emissions legal turbo idea was viable

also my budget was to get the most bang for my buck the cheapest would be to find a donor with an ls motor and do an engine swap but again my skill level isnt at that level since everything i can do i am doing myself

You should be able to build a 400+ HP 350 for not a ton of cash.

AFR 195 heads, decent roller cam. I went for a stronger bottom end on mine, so I did a Dart block, forged pistons/crank/rods.

Is this a smog legal setup for CA? If so, what kind of exhaust system are you using?

Hedman 68301 headers into catted 2.5" exhaust.

If you have a federal label you can run the 66307/68307 headers (no AIR tubes).

The heads(AFR 195), cam(custom grind, so not technically legal but milder than other legal cams), intake (aluminum dual plane w/ EGR (ZZ4 10185063), carb (stock Q-Jet), distributor(Stock HEI with MSD ultimate HEI kit, not really needed except for data logging and rev limiter), headers(68301s mentioned above) are all legal. The 400ci is technically not, but you could make pretty much the same power(but not the same torque) with a 350.

All of that said, I haven't smogged it yet but I have little reason to believe it will do badly. the previous engine(with just a bit more cam) passed the biannual smog easily since 2004.

That first cam is very, very aggressive and would have no chance.

The second will do just fine. I would look for a hydraulic roller with similar duration at .050. Keep LSA above 110. (I'm not a cam expert - a call to Chris Straub at Straub tech will get you a great setup as well)

You want the 3701 if you go Edelbrock, 3706 is for the late 80's iron heads.

The first cam will pass smog easily, not so sure on the second.

Something like CRN-109671 should do OK on smog. Which block are you planning on using? Original, or picking up a later model block or aftermarket block?


Those are actually heads, not headers. Either head should work. If you're going with that hydraulic flat tappet cam, an AFR 180 might be a better choice. Also if you're staying 350. JB78-L82 just did a build with the AFR 180s that he loves.

The AFR180s will flow better than the TFS 175s. If the $300 isn't a huge issue, I'd just go with the AFRs. Up to you.

Well the price isn't an issue I guess I'm just looking for the most bang for my buck and still be legal you know? I want to have the corvette power so I want the best cam and heads combination along with a decent intake that will pass smog and give me the most power...also I planned on using the original block and carburetor and replacing everything else as required to give me the most power and still be legal..that is my goal
