Ok , so here's what I think . As you said , forced induction engines don't like overlap because that blows the mixture out the tailpipe . Keep the overlap down and more of the mixture gets into the cylinder and thus more power . The problem with that line of thought is we have no mixture in the...

OK , .050 . That's good to know . Why no overlap ?

As I stated earlier you need to find out what the specs are when the lifts and duration were measured . The stock cam looks like specs I have measured @ .050 . Why don't you want overlap ?

What Chris said is correct about the limits on the TPS . But , and there is always a but , there needs to be a linear transition from the low value to the higher reading . You should see a constant increase in the voltage reading , with no dips or dropouts , when pushing slowly on the gas pedal...

When I rebuilt my 91 4L80E , I couldn't find anything wrong with the internals . Trans just had no reverse . Nothing was burned , broken or cracked . What I did do was to replace all the bushings and the seals . I got GM rebuilding tools off Ebay and checked the reverse pin . That was the...

Yes , I know you have a wire to plug in . Does it have the vac pod ?

Which oil pump drive do you have ?

Yep , they came stock . I did one in my 86 . Had to move the crossmember back , shorten the driveshaft and do a little on the shift linkage . . You should have holes in the frame to move the crossmember back and deal with the driveshaft . And figure out what was done to the electrical part of...

That is the CK series .

Which series truck do you have ? Old body style is R/V , newer is the C/K series .

Very nice . Much better than my POS .

The door frames look pretty good . If you send me a number or email , I'll send you some pictures . You can PM me if you like .

Let me get a better look at them . There is not much left , body sitting on the chassis but it does roll . This is a cab and chassis truck so it has the shorter 14 bolt rear . 91 6.2/4L80E but that is swapped into my 86 . No wiring , fenders , bed just the cab and doors . It's pretty much picked...

Too bad you're about 6 hrs from me . I've got a CC body that I'm going to trash and I think it's got good door frames on it . I'd have to check to be sure .

I turn rotors when new , haven't had any new ones that would not cause a problem if they were just installed . Maybe it's a cheaper brand , maybe the name brands don't want you to know how bad they are when new . Bought a new set of Bendix drums for my dually years ago and had to turn them 3...

What's the brake code ? JD7 , JB6 ?

Has the group ever thought about having a " Tool Room " ? Tools for the 6.2 and 6.5 that can be circulated between the members . Not general tools but very specific tools .

I'm working on a 81 Firebird and there is a good size ground in the factory manual and on the car from the trans to the body .

Ferm , what's up with the PAG stuff ? Can I add 46 to a system that I think I put the 150 in ?

I have a 91 Suburban with dual AC and can say that you need to run the rear with the front on . Makes a big difference in the cooling . Sounds like I need to see if the Otube is in the condenser as when I replaced it with a new one , there was not one installed . I did put one in the " original...
