    Catbox, I had read the summit vortec heads were not prone to cracking like the factory as also. I will definately go with the summit vortec heads Thanks for the reply Tracy

    Advice on freshening up a 350 tbi

    Thanks Bucket thats just what I was looking for! My concern was that the TBI heads might make more in the ranges I was looking for but if not I won't mess with the TBI heads and will go with a set of vortec. The Vortec heads will leave me more options in the future anyways I figured I may be...

    Advice on freshening up a 350 tbi

    Mcarlo86, I'm looking for around 100 hp more and I can see TBI would be difficult if not impossible to get a chip for. Plus after learning more about the TBI I think I'd much prefer a system that I can tune not some computer that says what I can and can't do. I am going with a Q-jet for sure...

    Advice on freshening up a 350 tbi

    I have a spare 350 tbi that has some miles that I have decided to freshen up and switch my burb over to old school setup/ carb. Ive never rebuilt an engine before so I have a few questions. There's not much ring ridge at all so I was going to hone and put in New rings, bearings and gaskets. Also...

    350 tbi timing

    Mike, thanks for posting it appears my math is off. These figures have me leaning more towards just doing a 12 valve cummins swap instead of trying to milk this 350 tbi Tracy

    350 tbi timing

    I'm OCD! I can't stand a sluggish engine when I know good and well that with a little tuning it will become throttle responsive and a light touch of the throttle moves you down a road. Not to mention the extra 75 miles per tank of fuel that gets you a lot further when road tripping and trying to...

    350 tbi timing

    Thanks for all the advice! It sounds like I should just set it to zero and mark my distributor location! Than I will fill up with premium grade and make timing bumps and test drives. When it pulls the best I will lock it down and run it right there. Looks like some have realized gains and maybe...

    350 tbi timing

    Thanks Ben that's what I was looking for. Do you have to run higher than 87 octane when you do that?

    350 tbi timing

    Thanks Bucket! Would I have to reprogram my computer or can I just bump my distributor up a bit?

    350 tbi timing

    Hey guys and gals I know I'm suppose to set the timing at zero and the computer adjusts the advance until the knock sensor tells it to stop. My question is if I bump my timing 2 or 3 degrees and run 92 octane fuel so the knock sensor allows it to advance will the 350 tbi see any benifit??? Ive...

    Starts but quickly dies, any low tech tips for diagnosis?

    That's where I'd look first as well

    SUBURBAN 1990

    The swap only took one day! Being a direct bolt in its simple and easy. You were ahead of the times back in 08 my friend and now everyone is seeing the bigger picture. Grin In my case I I was having a hard time finding a rust free suburban so when I found one at a reasonable price I bought it...

    Time for a crate engine. Suggestions?

    I've never tried one but West Coast Engines seems to have great reviews and a good warrantee. They have a 300 hp 370 ft lbs of torque 350 they build that your stock tbi works with and they give you a new chip to calibrate. Comes with roller Cam and 50,000 mile 5 year warrantee. Apparently it's a...

    1988 Suburban new project and new member

    Welcome friend! I recently joined and am working on an 89 suburban also rust free. My 350 tbi ran like crap when I got it but a new fuel pump and tbi rebuild brought it back to life. Fuel pump was $50 and tbi rebuild kit was $35. These tbi units are 10 times simpler than a carb so don't be...

    Suburban Build For Camping/Hunting/Fishing

    77 K20, I 99% snow wheel no rocks or mud for me. We used to always go with a shovel, high lift Jack, and chains and always made it home. A lot of people would be surprised what you can get out of with just a shovel and a high lift Jack. A winch with receivers for both the front and back of the...

    Suburban Build For Camping/Hunting/Fishing

    I'm debating between a bumper mounted winch or a chainsaw winch with built in winch points on all 4 sides of the Burb! Maybe both! I always carry a chainsaw regardless in case of downed trees in the road which can happen in the woods and has happened to me before

    Suburban Build For Camping/Hunting/Fishing

    It actually just dawned on me that you might be thinking along with others that I'm building this suburban for "Overlanding" because of my user name. Lol I should clarify that I'm actually building it for "Camping, Hunting and Fishing" as the title of the thread says. That's pretty important...

Sanded and painted the white spoke 16" rims black and went with Buckshot Mudders! New fuel pump, fuel filter, rebuilt...

    Suburban Build For Camping/Hunting/Fishing

    Front axle is a big knuckle Dana 44. came with 4:56 gears and Detroit. Tires are 36" I agree it's pushing it a little but I got a screaming deal on the donor vehicle that came with the 14 bolt FF and Dana 44 4:56 gears and Lockers so grabbed it up. I figured I can always sale the Dana 44 and...

    Suburban Build For Camping/Hunting/Fishing

    Shiftpro, It has Detroit locker in the front and a Lockrite in the rear. I haven't long traveled the front yet but thinking of going with 52" springs and moving the axle forward as you mentioned. Does this sound like the right direction to go? I am running the slip joint off the TC right now...
