I have an 89 c1500 with the tbi 350 and I was wondering if anyone has a rough idea what kinda power I can make with it, with supporting mods such as longtube headers, edelbrock carb swap, summit k1103 cam and a high rise intake.

Not as much as you want, and fair-to-middlin' chance of wrecking driveability, fuel economy, and/or emissions compliance. I'd be looking to upgrade to an OEM or OEM-style roller cam even if it meant picking up a different core engine to start with. You'd also need a different distributor, with centrifugal and vacuum advance.

Keeping the EGR? Vortec heads make that difficult.

Perhaps a moderator will move this thread to the LSX + Carb Swaps sub-forum.

Just replicate GM's 350/330hp engine. Should be 250hp at the tires. Vortec heads, 476 cam, long tube's, GM aluminum intake and Holley 600 carb.

What would my rpms look like at highway speeds say like at 70-80mph with those gear ratios?
