Doing a cam in the car is not fun.

unless its a 70 v8 u can get away with it . maybe while i have the car down for 3 months for paint and body work , i might 3400 swap it

[michi]

i kinda was wondered no one said wot-tech already. I have to say as much as i like the 2.8/3.1 engines, if i would mod our V6 engine i would go with a 3400 or atleast 3100... but its your thing, just wanted to say cause i am thinking about modded 3400 swap too

[Asylum]

For what it will cost to "hopefully" get 200 hp out of a 3.1 the 3400 should be a no-brainer.
With headers and any sort of tune, a 3400 will be close to 200 easily.
And will be a much tamer and reliable car to have to deal with.

i might throw a 3400 into the modding pot along with suicide doors and a suicide hood . ive asked this before but i for get now. what gm cars had the 3400 ? i can buy a wrecked one and part it out to fund the build

Almost any N-body car that was sold between 2000 and 2005 with a V6 was either the 3400 or 3500. W-body's were the ones who got the 3800's and such IIRC.

Info from Wiki

LA1

The LA1 3400 ("E-code") was a bored-out version of the 3100. It retained the OHV layout of the previous engine, and was first utilized on the 1996 U platform minivans and appeared in a car for the first time in the 1999 Pontiac Grand Am and Oldsmobile Alero. A 92 mm (3.6 in) bore with the same 84 mm (3.3 in) stroke brought the displacement to 3.4 L (3,350 cc/204 cu in). The LA1 was updated in 2005 to share common parts with the LX9 3500 GM High Value engine. Power was up to 170 hp-185 hp (127 kW to 138 kW) and torque was 210 lb·ft (285 N·m).

thanks, i can start a search for a doner car now

[Barry]

You live near me. Get a 3400 from Harrys. There like 95 bucks. Grab one and put new gaskets in it and call it a day. I see them all the time in the yard.

Much cheaper than getting a donor car.

[ClonedGTZ]

i can pick up a wrecked car for like 500 bucks off CL, part out the rest and scrap the shell

[3X00-Modified]

If you got the time go for it, but some people don't have the time to do that.

[ClonedGTZ]

its easyer on me cuz i dont own a truck to haul a engine. ill need the trans for the 3400 too right or ?

[3X00-Modified]

no, all the blocks are the same as the 2.8's so you use the same trans as you have... this is why its a bolt in swap... only the motor and sensor change, and you juts have to make a bracket for the front mount if you have that style.

there are tons of 3400 swap threads on here so look those up, and check out 3400swap.com for general info on the swap, obviously some stuff will differ since your a MPFI setup vs a SFI install.

[ClonedGTZ]

ahh good i can keep my trans and get it rebuilt . ill search around for them.
