I DID THIS

Last time I had to do the heads on my moms car i got machining for so cheap i said wtf go for it.

intake matched to heads
tb/manifold smoothed out
mild port and polish
cam was shot and no one had a replacment in mn but checkers had a comp cam in stock that someone ordered but never bought it so i bought it
3 angle valve job
shaved heads a little to get higher compression

I put a g meter in it once and it said it ran 14.6

For my moms driving she doesnt notice it but it pulls way harder now

Also the rockers on 2.8L & 3.1L V6s are basicly 1.5 ratio sbc rockers. You could probably upgrade to a 1.6 sbc roller tipped rocker for a little more lift on the stock cam.

i wouldnt do that the pistons are already really close to the valves

why doesn't he just upgrade to the 3.8?

-E
The 3.4 is a direct swap for the 3.1. (At least it is for the mid 90's 3.1)
He'd just have to swap over some sensor's and the injectors. I was temped to try this swap on the wifes 95 Grand Am 3.1, I'm getting sick of replacing lower intake manifold gaskets, but the 3.4 has the same problem. :headache:
