    350 cam options

    Very true, perhaps it had to do with the engine management system? Or due to the great cylinder head design they used that b body cam... Since it made excellent torque and good hp without having to rev the dog mess out of the truck? I know I would like to hear the true story.

    A machinist , a turbo and his L31 GMC

    Just curious how this build is coming. I intend to boost my suburban as well. I too am looking for more of a towing rig with great merging and passing abilities.

    350 cam options

    Agreed... Lol they are the same grind... I personally like the lt1 cam. If my motor wasi n a 2wd rcsb I'd bet it would fly for what it is. Hell my big ass suburban will hit 92mph in a quarter mile from a dead stop, but I have other supporting mods.

    Rear gear question

    Sorry, I see my error. You're running the 395 cam. I saw 383 When you were describing your camshaft. I agree with you on not fearing the gear! I had a few mustangs that I would race in my twenties. 5spd and 4.11's is a blast to drive! If I can't find 4.30's I'm going 4.56's ... Get this big...

    That's him, but keep in mind that's to the tire also... Through the trans and drivetrain loss... In a 4wd truck. It revs a lot better I'll tell you that for sure. Before the swap my truck fell on it's face around 4500 rpm and strained to hit the shift point at wot. Now it pulls straight to shift...

    350 cam options

    I have a f body cam in my suburban. I put it in about a month ago. I can tell you this. From idle to 4k the lt1 cam and l31 cam are fairly similar. You probably wouldn't notice much of a difference. However 4k to shift point is completely different. I scored my cam for next to nothing. Was it...

    97 5.0 vortec backfiring through exhaust

    Superdave, I've verified the wires 3 times to be honest. 4months ago he called me for a no start issue. I couldn't honestly say what it was doing when he had the dizz, plugs, and wires replaced. The backfiring is a new issue. Also I pulled the crank sensor just to see if maybe for some odd...

    97 5.0 vortec backfiring through exhaust

    Richard, The first thing I did was try a different cap. Made no change. On another note I pulled #7 spark plug wire it made no change in idle quality.

    97 5.0 vortec backfiring through exhaust

    Honestly have no idea if it was offset correctly. I asked him about the distributor and he said he wasn't sure what they did at the shop. I've thought about the timing chain too. He is prettymuch tapped out at the moment. I've got about 5 hours in the truck for him. Checking this and that. In...

    97 5.0 vortec backfiring through exhaust

    No sir, I do not. I sincerely wish I did. I'm running an elm327 and torque app. I bought it about a year ago just to check dtc's. It will give some live data, but it is not that advanced. I can view the timing advance, but I don't think it's accurate at least on these trucks. I did put it back...

    97 5.0 vortec backfiring through exhaust

    Yeah, I pulled the cap and replaced it with another. Didn't change anything. To be honest. I worked on this truck about 4 months ago. It just died on him. So he towed it home and I came over and started checking things. Found that the dizzy had just been replaced. So I checked the icm, the coil...
