I know its just an engine build, but I figure that I should document this stuff somewhere, and you guys like looking at pictures.
The motor is a small block Chevy, your run of the mill 2 bolt 350 out of a '77 Camaro. Looks like it is all virgin. Came in the Jeep. Ran well enough to drive it home. Then it sat, for 3 years while I was away at college and had no money.
We moved a year ago and it ran fine going onto and coming off of the trailer. Then it sat, for 8 months, in the garage. I was going to paint the block proper orange and clean everything up. Took the plugs out and rusty water started shooting out. Uh oh.
I guess water or condensation got through open valves?
Cleaned the walls. #3 has some pitting.
I wanted to build a hotter motor and drop it in when I was ready, but I don't have that option anymore. I want to drive this damn Jeep already.
I talked with some of you guys, my machinist, and Comp Cams, and I have a plan of attack.
My budget is $1500, but I'll spend more if it means not cutting corners. Nothing crazy, just a slightly-over-stock rebuild. I'll keep a running total.
I scored a set of 062 Vortec heads off my friend's toasted Suburban engine. They might need a valve job. All of the seats and seals looked clean except for one exhaust valve that is a little rough. Machinist said he might be able to just lap that one. Hopefully all they will need is a hot tanking and the guides trimmed. If he recommends a valve job or replacement valves, then I'll do it. Reusing the stock self-aligning rockers.
Machine shop is going to hot tank, freeze plugs, bore 0.030" over, and install cam bearings. My crank is a bit groovy and might need polishing as well.
The pistons will be -12cc dished 1.561" CH. These.
Head gaskets are 0.026", bringing the static CR to 9.34:1.
The cam is a Comp 12-318-4. Comp thought this was the best fit for my application, and what I wanted to do. I'd hate to say it, but she's going to be cruising on Saturday nights more than on the trails, and I'd rather trade off a bit of low end torque for a rumpity idle and more mid range. It's extremely similar to the Isky 270 Mega that someone else on here recommended. I was shocked that Comp recommended their equivalent cam.
I'll be flushing and buying a friend's B&M 2500 stall. The electric fan should be able to handle the extra heat this will put out.
This cam brings the DCR to 7.65:1 and the cranking PSI to 150PSI. Well within pump gas territory.
I just finished rebuilding my Quadrajet. I'll also be needing an Edelbrock Vortec intake.
I'll update as things progress. Going in to the shop Monday.
