I'm researching the idea of swapping an LQ9 into my '88 Trans Am. I've already got an LT1/T56 in there now. I work at a dealership and work on these trucks everyday, so I'm thinking the newer engine would be better.
I was wondering, if I got the engine from GMpartsdirect and got a used wiring harness, and LS1/T56 bellhousing to put on my current T56, anything else I might need?
Anyone know what kind of MPG I might get with 9" with 4.11's?
