Does anybody know where I can find a place who makes long tube headers for 189 cui (3.1L) block? I think the 3.1 is the same as the 2.8 just bored out (30 over I think) so if the headers fit a 2.8, i'm pretty sure they will bolt up to my 3.1

Thanks for your help

just outa curiosity, how come your putting a bunch of money into your 3.1? why not just save for a 350?

I don't think there are long tubes out there for the rwd 60degree v6's, but I know that pacesetter make's headers for them.

V8 swaps are waaayyyy more costly than you woudl think. especially if you intend to stay emissions friendly.
a few well choosen bolt ons can make a world of diffrence in a cars performance. jsut look at little g's ride, started otu runnign 16's. a few good decisions later it is on the brink of 13's.

an 02 v6 camaro is a far better starting point then the lowly 3.1's offered in the early 90's and late 80's putting down probably close to 50 more hp off the showroom floor.

that just makes the gains of gearing and tunign even more evident at the end of the day.
besides, y9ou can't go wrong with good chassis and suspension prep. if at any point he does decide to do a V8 or different V6 the car will already be prepared for it.

you could always put a grand national engine in it

no, grand nat engine is a worse swap than a 350

nothing wrong with a 2.8 - i had one in the 15s at one point, then i killed it, it was a tiard motor


need any help with anything 2.8/3.1/3.4 related let me know, i got a ton of ideas i can throw at you

It will be done ... come to find out they don't make long tube headers and i know about pace setter ... but I think i'm going to switch out the rear end first to a posi ... they did say that it couldn't be done, but it will be ... trust me it will ... the 350 swap would be ncie BUT, i need new breaking system ... new trans ... new suspension ... etc. and i dn't have the money for that ... i'm probally going to build another V6 from the gound up beefed up ... i have no idea what my car would run right now ... but i'm sure it wouldn't be too bad as soon as i can ... i'll take it down to the track and get it timed i'll let you know how it goes (i'm thinking 16's at maybe 90-95 mph)
^too much to ask for?

well if you're interested in building a v6 from the ground up. how about a 3.4l engine w/auto trans. im selling it out of my 94 firebird, including all accesories, harness, and ecm... 300 bucks for all that. just a thought...

Yea, way to much to ask out of a stock, or close to stock 3.1. The motor was rated at 140 hp and 170 ft-lbs of torque (Exact same specs as the 3.1 in my '91 Lumina).

The Lumina (with the only mods being !jack, !spare, and hacked airbox) ran a 17.4 @ 78.xx. If your car is running well, I would expect around a 17.1 or 17.2 @ 80ish mph.

yeah. i agree with justin, stock around 17.0 at best, trapping around 80. 90-95 mph traps should be around 15.2 give or take. my 95 caddy STS bone stock trapped 97mph, at 14.8

give that puppy some gear and watch the et's fall. :)
stock you most likely have 3.42's, 3.73's woudl be a little better, 4.10's would be good for ya, and 4.56's would get the job done :) hehe
honestly, 4.10's are a good all around gear for most V6 cars. you will see a huge gain in performance without a negative effect on your gas mileage, slight if any effect on mileage at all.
add a mild torque convertor when you rebuild teh tranny and you will really see a huge improvement.
