can i swap a 95 3100 into a 99 malibu

[yukon joe]

can i swap the 95 into the 99? or even a 3400 without any problem ?

A 3400 would be preferable obviously, and a pretty simple swap. But yes, a 95 3100 will bolt up to a 99 Malibu. There will be some small things to work out (mainly EGR related), but pretty simple overall. I'm almost positive someone was asking almost the exact same question sometime last week...

95 3100 is a small port POS... Not worth swapping if you ask me.

But did the 99 Malibu get a large port or small port 3100? I thought only the GAs got the large port in 99, or maybe that was the 3400...

Crap your right... the 99 malibu may be a small port... I thought they were 3400's by then though...

Time for google to answer.... lol

Your right... I was wrong... 1997 to 1999.5 L82 engine Notice 1999.5 for the year... lol, so really I'm half a year right
