Hey All,
Was looking for a good place to put this information, and I stumbled into this forum. I am currently working on a 1987 B2000 build up of the stock engine. Before I got too far into it, I ran a base dyno on my truck:

These runs were done with a Weber 32/36, pacesetter header, and 310k miles on the clock.
The following is a list of upgrades I have already purchased and will be working on after I get my block and crank back from the machine shop:
3 angle valve job
Light head porting behind valves
Delta 272 cam
Performance F2 valve springs
38/38 weber w/ jet kit (for the tuner)
Weber air horn
Electric fuel pump
Electric cooling fan
130 amp alternator
10:1 compression pistons (.5mm overbore)
Fully balanced crank/rotating assembly
Porting out my pacesetter header
I also already have a wideband installed, and an oil pressure gauge. My goal was to get to about 100 HP at the wheels. My engine was noticeably tired after 310k miles, I suspect with some tuning and some timing I'll reach my goal.
Anyway, I like wasting money on the junk I love more than spending 50k for a brand new vehicle I'm too afraid to get rock chips with. I'll post the updated dyno results after the rebuild and break in period is finished.
Thanks,
Matt
