Hello, I need your opinions. I have a beautiful 1989 GMC 1500 all lowered, painted and a cool interior but it still has stock power. 305 tbi only 99k original miles, 700r4 TV cable model, 2 piece driveshaft, 10 bolt 3:73 posi rear end. I would like more horsepower!!! I have a good running Chevy express 3500 with a ly6 4l80 combo with 144k which could be installed with alot of work. I have up to $7500 to spend but want to make this journey simple and fun with a finished truck that's reliable and enjoyable. Not a wrenching nightmare! I just want to lay some posi!!. I really don't have any access to a ls tuner guy or motor builder. Not close at least. I'm a good wrench though. What would you guys do????? Upgraded 350 Tbi crate motor (easy install and get to keep all gauges and cruise) , 383 crate motor (more work but not to much more. Will lose some options) or freshen up the Ly6/4l80. Lots of work and power. Or just leave the truck stock and cruise it!!
