[ENGINE PROJECT] Engine guys step inside, need some help/advice
I have a 350 short block that I want to do heads/cam/etc. upgrades on and toss in the vette. We pulled the engine from my friends pickup like 3 years ago and it ran great up to the day we pulled it. However that was 3 years ago... If I clean it up could I use it without doing a complete tear down? How should I get started?
Here's a bunch of pics of the SB:

If it ran good, I would tear it down, clean it up and out and maybe re-hone the cylinder walls. Check your bearing clearances and if they are within tolerances, re-use them if you are on a budget. Personally, if it specs out ok, I'd spring for a complete set of bearings. It looks like to much rust has accumulated over the entire block. Good luck with your project.

I think you should tear it down, you got it on the stand you won`t get a better chance than now to do it right. If you doing it all yourself, the only extra ya got to do is boil the block. A set of bearings does`nt cost much considering what your doing to the top end, a quick hone job and your about done. And be sure to check your crank and cylinder walls so there within specs. Good Luck!!!!! :chevy

looks like I will have to tear it down then. should make a fun winter project...
I'm shooting for 300-350hp 400ish tq. Nothing to crazy, just a fun weekend cruiser with some power to back up the looks.

350HP with those 4 valve relief pistons will be a challenge to keep it reliable. The cylinder walls show signs of high mileage and the crosshatching that shold be there is not very evident. I think you should think about going to some cheap Speed Pro hypeutectic 2 valve relief pistons or Kieth Blacks, either would run around $200 plus some bearings and rings. The cam should be a matched one to your car, intended useage and drivetrain. I think you will waste your time by honing that motor and doing a simple re-ring and bearing job. The effort to install a motor into a Vette isn't worth it if you don't put a proper engine in there in the first place in my book. You havent covered cylinder heads that you have or what kind of Vette you are installing it in. I noticed the C5 in the back ground, if this is your car and you are low on funds, up the collision damage deductiable to $1,000 and with the money you save, you can build your motor.

I plan on doing it right and taking my time to do it, the vette runs great just no power, so as long as it's running great, i'm not in a rush to pull the motor.
