i could probably do a lot of copy/paste... but i still need to fill in quite a bit about MAF tuning, since most of that article was written about speed-density...

3900 swap? Isnt that whats in a G6 GT?

Malibus had them too IIRC.

depends on the year IIRC(i know the 06-07 G6 GTPs have them, i think the GTs may have been 3500s though).... but it'* been in a few vehicles by now. the easiest one to source(and have to modify things the least) would be from a W-body... and the 06-present Impalas have them, and they seem to be all over up here... hard to argue with 240/240 N/A with an amazing exhaust note and decent fuel economy.

the F40 is also something that'* been on the table for quite some time...too bad only the G6s got them... makes for some more fab work for me...

would that be worth it? but a new nice motor like that in a old Monte?

financially? no, it'* probably a horrible decision since there are other motors out there that would drop in and work with half the work and cost, but this car has a lot of sentimental value.... not so much with the engine/trans, but i decided a while agoit was either going to have a big 660 or a N* breathing under the hood..... and a N* would be an even bigger PITA.

i've been considering another for that project.... and having them be twins externally, but FAR different under the hood...

Big 660?

60 degree V6

you win 1 internetz.

and since the 3900 is likely as big as they will ever get, i see no reason not to....

the direct injected 3.6 would be nice, but holy hell would that be a project within a project within a project.....

why not a 3.8?
