    TBI Cam recomendations

    To make a long story short, Went looking for a ticking noise that I thought was an exhaust leak and turned out to be lifters. After attempting to adjust them (turn the nut until the pushrod cant spin and then 1/2 turn) I realized that my lifters are probably on the way out (pushrods kept...

    454 exhaust recommendations

    Looking for input on 454 exhaust. Current set up is summit long tubes with 2-1/4” true duals (the dynomax kit I think) and cherry bomb knock off glass packs. I hate the sound and I’m about to throw on some 781 heads I got for cheap and an Edelbrock performer intake to match the oval ports with a...

    Tbi alternator wiring

    I think the alternator on my 90 suburban is going out. Took a look at it today and noticed this wire was cut (by previous owner presumably). Any idea why this might be the case?

    Q jet choke question

    Picked up a spare quadrajet this weekend and it’s an older version set up for a divorced choke. My truck originally came with a hot air choke but the port is now blocked off and I was wondering if anyone knew of an adapter or kit to make the divorced choke work with that opening or if there was...

    Small block and big block exhaust interchange

    Might be a stupid question, but will a stock exhaust system (post manifold) from a small block truck bolt up to a big block and vice versa? I have long tubes and true duals on my big block and I want to go back to manifolds and a 2-1 and wondering if I can just slap in the stock exhaust from a...

    454 intake manifold gaskets not sealing

    After suspecting that my oil consumption + low vacuum issue was the result of bad intake manifold gaskets, I was able to confirm that that was the case (see pics). Basically I had a leak under the manifold that was simultaneously sucking oil into the intake ports and not letting me get past...

    Power window relay issues

    Trying to hook up the power window relays and I’ve got some questions about wiring. I’m using the following diagram and I’ve got fused power from the under hood junction block going to 30, 85 is ground, 86 is to the switch and 87 is to the motor. If I ground 87a, I can hear the relays click, but...

    1991 gmc suburban stock shock question

    Just picked up a 91 gmc suburban 4x4 and now that I've got it on the road, it definitely needs some shocks. It's still got the quad front shocks but they could very well be the original factory ones. Rockauto has part numbers for inner and outer shocks, but I'd like to go to just one shock...

    Exhaust options for a 1990 suburban 4x4?

    Anyone have any suggestions for exhaust kits for a 1990 4x4 burb? most shops in my area are quoting 1500-2000 to build a custom exhaust and the dynomax kit I ordered from summit was designed by a blind man the way stuff is fitting up.

    Need help figuring out options for regear

    I have a 90 burb (350/700r4) with a 6" ORD lift and 10 bolts front & rear. I run 35" tires most of the time with some 33" studded snow tires for winter. A previous owner (not the guy I bought it from, but the dude before him) installed 5.38 gears in the 10 bolts, which I'm sure are fine for 40's...

    350 tbi idle speed

    So I’ve got this issue with my tbi 350. Normally at idle it’s around 700 at cold start in park and it drops down to about 400 in gear and will sometimes drop and rise and even die. I’ve replaced the iac valve and done the relearn procedure and still nothing. When I unplug the iac it’s fine...

    Question about 1990 Suburban & emissions

    I'm moving to Denver/picking up a new-to-me 90 burb in the next week and I had a question about emissions. I'm buying the truck from a friend there who has it registered in a county that doesn't require emissions testing, but I'll be in the Denver metro area so I'll have to bite the bullet. I...

    Broken valve guide boss/pillar

    I know I’m going to need to get some machine shop work done on these heads I just snagged, but can they repair this valve guide boss/pillar that broke off? Or is there a way I could use a different seal for just this one valve?

    Colorado K30 ownership

    Question for the Colorado folks on here: I'm currently daily driving my k30 here in Texas. Registration and inspection is easy and I don't think I get tested for emissions or anything, it's not registered as a classic or antique or anything. Is there anything I need to know before I move and...

    6.5" speaker mounting options

    I'm in the process of re-doing the sound system in my crew cab and I was wondering where yall mounted 6.5" speakers. For reference, the truck came with a 4 channel amp and 2 10" powered subs.

    Ok, so here's a question I've been floating around in my head. I've got the dual 20 gallon saddle tanks on my truck and while I'm currently getting a whopping 10mpg (LS swap in the future to hopefully raise that a bit), I'd like to add some fuel capacity for the time being. I'm going to be...

    Quadrajet from hell will not give me peace

    So I recently rebuilt my q jet, mostly to do throttle shaft bushings, but also just to give myself peace of mind that everything was actually done right when I rebuilt it the first time. Well now it's worse, and I'm not ruling out rebuilder error on my part, I just don't even know what's going...

    Power steering pump recommendation

    Any recommendations on a quality PS pump for a 454 truck with hydroboost brakes? My current one just started leaking and its only 3-4 months old (ordered from rockauto). This is the second leaking PS pump I've had since I bought the truck and I've verified its coming from the pump body and not...
