Right now my car has bbk shorty headers ( bought it that way) i have always used long tube headers on all my chevys with bigger motors. Would i pick up any hp if i put longtubes on? Reason asking its only 281 ci.If so what do you normaly gain? Im looking to get more hp out of this thing, any ideas on what to do next? I dont want to do any power adders just yet, so im looking for anything that would add power, i dont care if it is just a few hp here and their.

I picked up 18rwhp by adding the longtubes on my supercharged 4v setup, on a PI 2v I would imagine you would see about 10-12rwhp with a tune from the LTs. Long tubes are about one of the only bolt ons you'll see a gain like that from as well.

Agreed, 10-12 would be about right maybe a bit more if you got a d**n good tune. Just think of the install price if you are not putting them on your self. LTs are very labor intensive. I know my shop in Kansas said about 9 hours at the most.

I hear they are a pain in the a$$ to install. I was thinking kooks 1 3/4 inch headers. I would also do a k member also, i like the upr set up.

They were indeed a pain to do, especially on a 4v as no bolts where accesable from the top. Regardless of what people say, its is by far the easiest and fastest way doing it with the k member out. When I did mine I picked up a K-member kit from UPR as well, came with a QA1 k member , upr a arms and coilovers, and 4 bolt UPR CC plates. I couldn't be happier with it.

Thats awesome, think 1 3/4tubes will be to big?.

1 3/4" tubes would be good, just make sure you get ceramic headers. Keeps them from rusting and holds the heat in a bit better then chrome, allowing you to run cooler engine temps. If you really wanted cooler engine temps get ceramic headers and wrap them in ceramic wrap. A bit of a pain in the a** but you engine bay will run alot cooler. Bit off topic but my $.02

I would def try and get coated headers just for rust issues, especially on a car that sees winter or rain.

scott4.6

Yes i would get them coated ( if they didnt offer it ) I like jet hot coatings.

save money and coat them yourself. i agree with doing it for the rust issue, but not for the engine temp issue. unless you're running the car non-stop for over an hour at the track, they won't generate enough heat to cause an issue. dropping the k member and replacing it with a tubular one will be one of the better ways to do the install. it will also make it easier for future transmission work or, God forbid, having to work on the headers again.
