As far as I can tell by researching its the same block as the 3.5 but factory stroked and bored. Same heads as the 3.5 SOHC.
...
so was contemplating getting a 3.8 out of an endeavor and using the bottom end only.

I plan on possibly doing this swap into a 99 with a 3.5 SOHC, and using my existing heads and entire intake, so no plans to modify any wiring.

The 6g75 is basically a stroker 6g74. Easy swap too. Just bolt on your accessories and sensor, plug it in and go. Same wiring harness and ECU.

I realize we are talking about the 3.5L SOHC 6G74 engine here, but I was looking at something rather odd the other day that reminded me of this thread. With all this talk about using the bottom end only and using the same cylinder heads, I was thinking about the 3.0L engine and those cylinder heads. It dawned on Clearwater Cylinder heads lists the same cylinder heads for the 3.0L 6G72 engine and the 3.5L 6G74 engine. Here, see for yourself and take a look.

With that being said, couldn't I install the 3.8L 6G75 into my Raider??? If so, that would result in a power increase, a little over +85HP. Guys, am I way off here? I have fist hand experience with the blocks from the 3.0L SOHC & the 3.0L DOHC, but I don't know if that is the same with the 3.8L SOHC.
