This is my 1991 Chevy Silverado c1500 with a few goodies in it on the most extreme budget!!!
Ok, to start off with, the short block is a 1993 caprice block that got rebuilt at a local machine shop. Stock 4.00 inch bore and 3.48 inch stroke. It's a 2 bolt main block with cast crank and steel rods with flat top hypereutectic (might be mispelled) pistons. With the stock cylinder heads on it, it had a compression ratio of like 8.5 to 1. I installed a Melling high volume oil pump and pick up from summit. The cam is a summit piece. The part number to that cam kit is SUM-K1103. It's the cam and lifter kit. It was the best cam I could afford that would work the the vortec head swap that I will get to in a moment. While doing the cam swap, I also replaced the timing chain and gear set with another OEM replacement just to be on the safe side. Once you in there, it's no need to put the same timing chain back on if you done put some miles on it.
Now to the upper engine components. The heads are a stock reconditioned set of vortecs I scored off of a 350 core from a guy I know. They have the stock 1.94 intake and 1.60 exhaust valves. Stock springs and Retainers.
The intake is a budget Jegs piece that is dual plane and high rise for better low end torque and throttle response. I added a open 1 inch spacer to increase plenom volume. This helps with runner length and bumps up torque a little.
The carburetor used to be a holley 600 cam vacuum secondary unit but, I swapped it to a rebuilt holley 650 with mechanical secondaries and no choke(which is horrible during the winter time). I will be upgrading to a carburetor with an electric choke soon.
The distributor is a unit from Amazon or eBay with a 50,000 volt coil and a tune up kit I ordered from speedway.com. it has the autolite 906 spark plugs and OEM hei stock style wires.
I think that's it concerning the main components of the engine. I pray this info finds you soon and helps you with your build. Be blessed✊🏾✊🏾
