I was just wondering if it still has the original injector spider with pop off injectors or has it been replaced with the updated injector tree. I know the original design made for drivability issues and misfires all the time.

thats what i said. but since the mpfi ones cost so much i can see not wanting to buy them. i got a much smoother and more efficient engine when i changed mine though.

was thinking about the tuning out the fuel trim, that doesnt seem right. the fuel trim is there to tell you there is a issue. the trim is how much the pcm has to adjust the fuel to make it run right. for example if one of the injectors was not firing right(very common w/poppets) its got one sensor per bank so that bank would be lean and you increase the injector duration across the board to compensate so now you would have 3cylinders on that bank that are rich and the bad one who knows. or you could have one thats firing to much, lean the fuel out and have three lean cylinders and one crap poppet averaging it out

Your exactly right, and it can cause extended crank if you have an injector that dribbles it will load that cylinder and the intake with fuel causing it to go into clean out mode.

Mike, I admire your initiative in the small block V-8 engine swap, but as an old fart I have to wonder why you have bothered with all the so called new technolgy, the efi, etc. why not just slap a edelbrock bore on that sucker and be done with the bs? course like I said I'm old and still think a timing light and dwell meter will serve me well when when we get hit wit emp'*.

Because my truck is a 2002 model. In order for me to qualify for a "legal" upgrade, the new engine must be 2002 model year or better. Now, if my truck was 1995 or older, I could get away with a carb'd engine because they only do safety inspections on 95 and older. 1996 and newer they do emissions and safety.
