    '88 TBI Build

    Take a look at this website. I had this guy burn a chip for my suburban. Lot of interesting stuff on TBI mods including build ideas. https://harristuning.com/Tbi/

    Which 4 speed does it have? The SM465 or the NP833 overdrive?

    My 92 gmc

    I really miss my 1990 C10 that I had in college. Loved those seats.

    What did you pay for a square

    That is a rare bird there! I know the 5.7 was an option in '81, but this is the first one I have ever seen. Super cool that you fixed up your Grandpa's pickup. What gear ratio is in that? Most had 2.73 or 3.08's, but 3.42's were an option. My dad had a '79 5.7 with 3.42's and he really...

    MY 1976 GMC ROYAL SIERRA 15 SHORT BED WITH A 454 SPRIT OF 76

    I agree...as rare as it is, I'd leave it stock. Don't lower it. There is a local guy here who has an all original Spirit of '76 Chevy K10. 400V8, auto and 203 transfer case and factory AC. It is all white with blue interior. He bought it new. I've been telling him I'll buy it from him if he...

    350 to 292 swap.

    The 292 would work for what you are wanting to do. They do make decent off-idle torque and obviously were used in medium duty trucks for that reason. Low-end torque is the most important factor for pickups, especially if you are going to tow a little with it. Is there anything wrong with the...

    Questions about '74 All Time 4wd, HELP

    When you said this suburban is from Minnesota, make sure you go around with a magnet or something and double-check for bondo. It appears to have had some body work done at some point. (the grill looks like a '77, and the hood looks like it has been repainted along with what appears to be '80's...

    Trying to do this properly this time.

    The only time I remember someone getting riled up enough to be memorable was a 6.2-loving guy...haven't seen him around in a while. But I don't think he pissed anyone off, just had thin skin and didn't take jokes well.

    What have you done to your square lately??

    Did you do any other enhancements to the 292 like lump ports in the heads? I'm curious to hear how you like the Sniper on that 6.

    Champion radiator difficulties

    I looked and the part number for my Champion radiator is CC716. https://www.championradiators.com/product/CC716 I notice now that they list the inlet as 1.5". I didn't notice that when I ordered it. Just assumed it would be the same as the stock one.

    Champion radiator difficulties

    I have been searching for an upper hose also, and actually ordered the Gates 25484 also since I couldn't find one with 1.5" inside diameters on both ends.

    Wheel/Tire Opinion

    This is the size I put on my ‘68 C10. I’m very happy with them. Got Mastercraft Avenger G/T tires in white letter. Similar to Cooper Cobras or BFG T/A’s but a little less money.

    Champion radiator difficulties

    When your radiator arrives, measure it and compare it to the stock one. I’d be curious how yours measures up. I’m heading to Napa today to compare some top radiator hoses and see what I can find to make work.

    Champion radiator difficulties

    Since you have a big block, is that the wider radiator? I ordered the 3 core for a V1500 with a 350. I’m pretty sure the big blocks had a wider radiator. Maybe Champion’s big block radiators fit better? I will look up the part number of the one I got.

    Champion radiator difficulties

    Seems to fit pretty well after the modifications. The fan shroud ended up not sitting on the drivers side tank like with the stock radiator, so I decided to use a longer bolt and some spacers to hold the shroud out a little bit so it wouldn't rub on the fins of the radiator. Now I just need...

    Champion radiator difficulties

    Ok, so here is what I ended up doing: first pic is showing where the passenger top mount in stock position would hit on the radiator. So I had to move the top mount over. I lined up the left hole in the mount with the original right hole in the frame support. I had to trim the little lip off...

    Champion radiator difficulties

    The factory radiator gave up in our 90 Suburban, so I ordered a 3 core Champion aluminum one to replace it. I went this route because I’m not a fan of plastic radiator tanks, and this is supposedly a direct fit. Well, it is 1” narrower and about 1/4” shorter. I will have to move the passenger...

    6.5 Turbo reliability for an RV?

    I never did end up doing an engine swap. I was referring to the '78 model 454 that is in my motorhome. I highly doubt that a 6.5 would have the nylon coated timing sprockets...but I am far from an expert on 6.5's.

    6.5 Turbo reliability for an RV?

    I remember your ordeal with this and that is why I changed the timing set while I had the radiator and water pump out. That would definitely be one way to ruin a family vacation!

    6.5 Turbo reliability for an RV?

    I thought I should give an update on what I ended up doing. I pulled the radiator out and took it in to a radiator repair shop and they cleaned and inspected it. Put a new water pump in, along with a new timing chain and sprockets (to replace the 40 year old nylon sprockets before they decide...

    Should i fix the TBI or go to carb? And what's this wire?

    Before you ditch the TBI, read through all the info on this website: https://harristuning.com/Tbi/. Especially the recommendations section for 350 TBI's. There is a lot of good info on that site.

    Pro Flo 4- hate to try again after Edelbrock E-Street EFI

    I wonder how a TPI unit would work on that 383?

    New member. 87 V20 Stepside

    Pretty sure our oilfield roustabout business had one of those 37 or 38 V20 stepsides. I know that we had 2 or 3 of them in the '80s that were diesels too, but pretty sure those were '82-'83 models. From 1961-1987 we had close to 50 8' stepside pickups. That is a cool find!

    Anyone know what these rims are from?

    Sure look VW-ish to me.
