    1993 C1500 ride height question

    I have a 1993 C1500 Std cab/short bed truck and it has the factory "sport suspension", looks like an SS454 truck... It's on stock springs and I want to drop it two inches from where it sits now but given the age of the truck I'm wondering if it's already settled an inch or more and if I drop it...

    Stock TBI 305 block and heads useful?

    Is there some crazy universe that my stock TBI 305 block and heads would be useful or desirable for someone. Long story short I pulled my 208,000 mile 1993 TBI 305 motor a year ago. I've had it kicking around because I wanted to see what the intake ports, combustion chambers, pistons and...

    1993 C1500 Odometer issues - need to test odometer motor

    Long story short, the odometer has stopped working at 208,790 miles (sometimes it sort of works) on my 1993 GMC C1500. I noticed about a month ago the miles weren't really changing. Since then focusing in the operation of the odometer I would say it either flat out doesn't work or when it does...

    1993 GMC C1500 New engine - fuel pump question.

    As the title says I'm installing a new engine in my 1993 C1500 that will make an estimated 350 - 370 hp. I know from reading everything that increased fuel pressure and a new upgraded fuel pump will be required. From the performance thread in the sticky's on this forum it seems the TPI third...

    TBI Fuel injector oil ring question - 1993 C1500

    After 206,000 miles on my TBI 305 I'm rebuilding the TBI unit for the first time. I'll be doing most of the ultimate TBI mods while I'm in there but I ran into an odd little thing. On other TBI units I've worked on and the one in the thread link attached below there are metal rings that go...

    Limited slip lube question

    Long story short... 1993 GMC C1500 with a 10 bolt limited slip rear. Had the rear rebuilt at 185,000 miles due to a bearing failure. Installed new limited slip unit, gears and bearings at that time. Drove the truck for 10,000 miles with no noises or other issues and then changed the diff oil...

    1993 GMC 305 injector question - 200,000 drip?

    So as the title says I've have my 1993 GMC for about 15 years. It's a 305 with about 200,000 miles and for the most part the engine is strong for what it is... In the last 10,000 miles however I've noticed a stumble at idle which I believe is due to a slight drip I get from the injectors every...

    1993 GMC fuel line fittings.

    Maybe I have more money than brains but my fuel line from the filter to the throttle body is getting pretty rusty and I'd like to replace it with braided SS lines and AN fittings. Does anyone know what thread sizes I'll need for the ends. I guess in the end I like the flexibility and hate the...

    C2500 upper front A-arm on 93 C1500

    So as the title says I'm wondering about the 3/4 ton tubular front upper A-arm as a replacement for the stamped steel piece on my 1/2 ton truck. First I'm currently not interested in lowering my truck yet, until I get a newer truck this truck has the dual role of fun street and going camping...
