Hey guys, this was totally not on my agenda...I saw a 91 z for sale last week, looked at it yesterday, and am buying it for a daily driver! 305 TPI 5spd car, awsome condition(got it for 3k). Since I havnt yet sold my SLP headers, I'm thinkin about keeping them for this car. I've heard various opinions about the large tubes on a 305. A stock 305 doesn't really flow enough air to warrent the bigger tubes. Since this will be just a daily driver to enjoy, I have no intention of installing a 350 or spending a lot of money to go faster with it, but why should I not use what is one of the best headers ever built for our cars if I already have them? Looking for opinions! Anybody running large tubes on a 305? Any input is greatly appreciated. I do have a guy really serious about buying the headers, so I need to decide asap! Thanx!

 

slp's dont fit really well. If you have somebody how really wants them, i would sell them. Look into hooker 2055's, or if you want 1 3/4, which wont hurts anything, look into dynodons headers, he is here in the boards, they are the nicest best fitting 1 3/4 shorties available for a 3rd gen, not the cheapest, but really good an have a very nice y-pipe setup.

 

If you just want to drive the car, then why mess with the hassle of installing headers? They aren't a simple addition, and they aren't really well matched to the rest of the car... Why bother?

 

Just figured I'd maybe use them since I already have them. Now I wish I would've kept my superram! Does anybody make a nice aftermarket system that bolts to the stock manifolds(like the banks system from back in the day)? I would do that since the car will need new exhaust within a year or so.

 

I have the SLP 1 3/4" on my car and they fit well. Does not interfere with the steering or brake lines which can be moved a bit for clearance if need be.

Of course with any F-Body, it's a pain to put headers on.

 

I also have SLP's and they do fit well. The reason they don't fit as well on some cars because the K-member is up to a quarter of an inch to the left. You can tell 2 ways, on Camaros the intake snorkel is not straight, on 3gen f-bodies the left front tire sits more to the inside than the right. This is another reason why some Super Rams don't hit the wiper motor.

Keep the headers. They will wake up the 305 big time. If you have a G92 car, it will get you alot closer to the 13's. Does your car have dual cats?
