    Davis Off Road, crossover steering???

    Thanks for posting this. I hadn't seen their steps, and I've been looking. Yes, they are pricey, but the AMP steps alone are expensive. Add in their customization, and it starts to make sense. I've already reached out to get more details on the mounting.

    5.7 back fires through carb but timing is good.

    It sounds like you did the leak down correctly if each cylinder was at TDC when checked. Those numbers do seem high and variable. If you heard quite a bit of leakage through the intake, the intake valves are likely not sealing properly, which is of no surprise on a high mileage motor with...

    Electric fuel pump

    I've had good luck with the Carter electric pumps. Here is my go to; https://carterengineered.com/electric-fuel-pump-p76924 Always had good luck with these. Same design for over almost 40 years. Had one on my 57' Chevy back in the mid 80's. Now have one on my '76 K20. I do have a fuel...

    5.7 back fires through carb but timing is good.

    A leak down test is a good idea. That will help you know how well the rings and valves are sealing. If you have a valve that is hanging open, that would appear as a backfire. If it is high mileage, you could have quite a bit of carbon build up on the valve seats, keeping them from seating...

    241c or stay with the np203

    Key things to look for if the NP203 shifter is giving you a hard time: #1: Check alignment of shifter rods. The whole shifter can bend and get out of alignment or things just wear. There is a GM procedure for realigning the rods. Just search on the forum. #2: Excessively dirty: Commonly...

    241c or stay with the np203

    The only complaint I've heard about the NP203 is the shifter. While they are full-time 4x4, you can easily convert to part time and then add locking hubs. That's what I did. I swapped from a TH350 to a 700R4, but kept the NP203. The one thing you need to do is space the shifter forward since...

    Starter - Looking for Quality

    I have the Powermaster #9612 on multiple Chevy 400 small blocks and they have been very reliable. One source of a "bad sounding starter" is poor gear mesh between the starter and flywheel. Proper bolts are part of the equation, but you also need to check the spacing to make sure the gear mesh...

    Jet Performance Quadrajet JET Performance anyone gotz?

    When searching for a Qjet, I ended up going with National Carburetors #ND4528, based on my truck's specs (1976 K20, HD Emission, 400 engine). I installed it on my freshly rebuilt 400 and it started right up and idles like a dream. When I blip the throttle, the response is immediate, without...

    Help with starting 79 k20 400SBC

    It's always good to get back to basics; Fuel, spark, compression For fuel: * Is it old fuel. I've run into similar issues with using old fuel * You mentioned you know you have fuel getting to the carb, but do you know what pressure. May be worthwhile to install a gauge (at least temporarily)...

    Restored A/C Box (Engine Side)

    I purchased this restored A/C box from The Part Guy (https://thepartguy.com) when I was going to stay with the factory A/C system. Everything was so bad under the dash, I punted and switched to a Vintage Air system, so I no longer need this. This unit was listed to be for a 1976-81, I have a...

    Hi from IL

    Since it is a fairly small amount, it is possible the front motor mount brackets were moved. They are slotted and have fore/aft adjustment.

    Installing a New Exhaust System Including Headers

    I used the ceramic Headman long tube headers and they fit very well. I also used the Walker exhaust kit and it all fit nicely. I just replaced the connectors with some better quality ones. I had to use the Headman headers because they were the only ones with the AIR tubes and were CARB...

    Finding smog pump 1985 Chevy K20

    For my 1976 K20, I had RockAuto rebuild mine. The advantage of rebuilding yours is you know it fits. I think I also got the diverter valve from Rock Auto. There is also a rebuilder on eBay. Seller's name is "BZ Rebuilders".
