First post, on any site like this. I am a Fire Captain with Huntsville Fire and Rescue, I work on ATV's and anything gas. Also do remodeling on the side. I currently have 2 trucks I am working on, a 1977 LWB (red) and a 1976 SWB C-10 (blue). I was given a Cadillac 500 with a 700R4 transmission. The Cadillac is bored .30 over and has a front sump oil pan. The man was going to use it in his '49 Chevy 2 post, but went with a crate 502. The motor has 30k miles and has been sitting in his garage for a few years. Has A/C, and the 1977 C-10 does also. My plan is to put the 500 in the '77, refresh the head and pan gaskets, change the intake, and maybe a mild cam. The '76 I have a rock crusher for and plan to put a 5.3 in it. My question is what mounts and pan will I need? I have been looking thru Google and this site all day and cannot find the parts I need. I also tried Summit. Looking for part numbers, as I don't mind ordering what I need to make this plug and play. My plan is to take the truck to his house, install the motor and tranny, and do the finish work at my house. I will have about a week to get this all together. Point me to the right thread please, or someone who can give me some info on parts. I can fabricate, but being at his house for a limited time, I would like to get it in and out of his way as fast as possible. Also, he has a Muncie 4 speed for sale, short shifter, and host of other parts, non-caddy. early Corvette and an Olds BB.
