4.3 help needed

1949 S15

New member
Hello all. Thanks for the add. I have a 1989 S15 with a 1949 body. The 4.3 has 166,000. I would like to rebuild this winter with vortec heads, Edelbrock 2114 intake and a power adder. But want to keep tbi. It runs great really. But not enough power when towing my pop up. It's geared 3.42. I will be adding a Bravada rear shortly. That will help some. I would like to add an eaton m90. Any input would be appreciated.

Is the Bravada rear 3.42 or 3.73? They came with both. You could always use a rear end from an extended cab S10 with a 2.2 engine, they came with 4.10 rear gears
