I am replacing the v6 FI motor with a SBC 350 4 bolt main and I was wondering if anyone new what brand and type of headers will fit the best. Im on a tight budget and was thinking of Blackjack. whats the difference between shorty headers and regular?

 

Welcome aboard thirdgen.org.

There is a sticky in the top section of the Exhaust forum about headers available for our cars.

In general, "shorties" allow the exhaust routing to remain as stock. What you might call "normal" long tube headers have a tendency to reduce ground clearance significantly, and exhaust routing is problematic. Also, everything "good" for our cars tends to be higher priced, so don't plan on going cheap here.

My recommendation (also in the "V6 to V8 swap" sticky in the top section of this forum) is to go with exhaust for the '86-'90 TPI single cat application. The Hooker 2055HKR's are excellent headers, come with the best off-the-shelf y-pipe available for our cars at any price, and support good street power. thirdgen.org member Dyno Don also makes headers and y-pipes that are very good - search or PM him for more details. The rest of the exhaust, your choice of what meets the application above (a lot available). You can get a whole bolt-in exhaust for about $700-$1000, which is less than what it will cost you to buy cheap headers (shorties or long tubes) and have the exhaust completed by an exhaust shop.

Oh, Blackjack fits the definition of "cheap".

 

Thanks for the info But I forgot to mention We dont have any smog laws where I live

 

I just put a set of Hedman part # 68466 headers on my 91 rs with a 383 and they fit perfect with no modifications, just slipped right in. i do have solid motor mounts and no ac if that makes a difference

 

That doesn't change my recommendation one bit.

Do you have the rest of the exhaust in yet? How far do the collectors hang down? You didn't mention that. Of course they fit fine when the car is up on jack stands - it's "real life" when they start to show their true colors. As long as there are no speed bumps, dips, or slopped driveways in your life, they're fine.

 

Five7kid...

What do you think of the Hooker 16767 y-pipe and the 2460 headers?

I am currently running headman shorty 68470 and 17478 y-pipe with 3" high flow magnaflow cat and 3" magnaflow stainless cat-back.

I am looking to upgrade my headers and y-pipe as I am adding RHS heads, 3704 intake, 454 tbi base with 68# injectors and a 8-304-8 Comp Cams cam. This is going in/on my 350 TBI.

RHS Heads 76cc chambers, 2.02/1.60 valves, 230cfm
3704 Performer TBI manifold bored to 50mm to match 454 tbi base.

Should I keep my headman shorty headers and have my y-pipe custom made to open the flow? I have a guy near St. Louis who can make me a custom mandrel bent 3" y-pipe and powder coat it for a total of $300.

Ideas?

 

Sorry if this is off-topic, but do you know if you could maybe setup a true dual exhaust system on a 91 Camaro? and what headers and pipes would you end up using?

 

Not much. The pipe after the two sides join is only 2-1/2". It's intended to be an "off-road" replacement for the LO3 exhaust manifolds, y-pipe, and cat, hooking directly into the stock cat-back. Basically it's no better than what you have.

If you don't go with 2055HKR's, keep your Hedmans. The only part of the y-pipe that needs to be modified is the part after the two sides join. A Flowmaster 2-1/2 to 3" "Y" with piping back to your 3" would be all that needs modification.

Why the 76cc chambers? You're going to kill compression.

Slightly off-topic. There is a sticky about both true duals and headers choices in the Exhaust forum.

 

You really think those heads will kill compression? I was told by many that they were a perfect set of heads for my application and mods.

Five7kid... I value your opinion. You're one of the few over 18 on here lol!!!

 

First, there is no E in Camaro.

Second, if you live in the United States, yes there are smog laws. Federal smog laws that prevent the removal of factory smog equipment are in effect in all 50 states if you drive your car on the street. Just because your area doesnt check, does not mean you can remove parts on your own.

Third, if you're on such a tight budget, then performing modifications to your car shouldnt be on the list of things to spend your money. It takes money to make horsepower. Save your money and do things right the first time.

DCTrumpet, 76cc heads are for big stroke engines like 383's, or engines planning on using a power adder. For a regular 350 engine, you want 64cc heads to maintain a decent compression ratio (around 10:1). Using 76cc heads on a 350 will allow you to run 87 octane fairly easily though.

 

Thanks for all the input guys but ran into a bigger problem to deal with now. I pulled the engine and trans out of the camero over the weekend and I noticed that the transmission isnt going to bolt up to the SBC

 

Didn't read the "V6 to V8 Swap" sticky in the top section of this forum, did you?

(For the record, it's "Camaro", not "Camero".)

 

Yes I just noticed I spelled camaro wrong thanks and yes I did read it I just read it wrong so I guess I am just a Dumbass. So thanks for the info and I will do just fine on my own. Good Bye Yall

 

you aren't a dumbass for misreading, it happens to everyone. But i would disagree with the $700-$1000 exhaust being cheaper than any other options, my whole exhaust cost less than $400, that's hedman headers, and 2.5" true duals. Maybe it wasn't madrel bent but i remember reading an article in the early-mid 90's about a camaro running 11 second quarters with crush bent exhaust. In the end it all comes down to what YOU want. By the way I vote hedmans.

 

Hey man, don't take offense to what's written on here. We've all been where you're at now. I was new to the TGO boards 2.5 years ago and just new to boards in general. I had NO CLUE where to begin and fortunately a few guided me in the right direction. If you don't do about a thousand hours of searching on here you'll get certain comments from others, lol. Just teasing here so, no one else takes offense.

Sometimes you just need a little guidance and a direction to turn to. Most of us at TGO have contributed countless hours into our projects and helping others on this board. I have to catch myself sometimes when i see certain threads from newer guys asking questions that are so easily answered in numerous other threads/stickies.

Anyway, hang in there and don't give up on TGO please. If you've done a very thorough search on here and still have questions please post a thread or if you just can't seem to find what you need in a thread just ask.

Take care and stay on TGO!!!
