Yeah, it used to run very well...could climb to 80 in 5th with no problems. I had to replace the rear gears so I was running around with 4.10's in the back for a while...when I put the 5.29 back in the truck was crap.
This engine does not have the stock injectors...everything about the EFI was modified by LC to work with the motor.
what should idle be at when I check the timing? (well, I thought I had an idea about the motor...guess i will work on it myself a little more)
(edit) - when I say close to 200hp...I mean 175-185 hp. Sorry about that...I know there is a big difference when it comes to such a small motor.
