305 motor upgrades
 

Hello all - new to the group and brand new to car restoration. I have an 88 MC SS. This car has a cracked block. I was able to find a used, running 305 that I picked up for $150. This car was verified running when it was removed from another 88. My question is if I should start replacing parts while out of the car. Manifold, heads, etc?

Any help and guidance is greatly appreciated.

Biggest thing you can do is change the gaskets while engine is out. Oil pan , timing cover front seal , rear main seal and valve cover gaskets would all be a good start. And while the engine is out its the best time to change the front pump seal on the transmission. Good luck

i would change the timing chain ,water pump ,fuel pump, air filter , oil/oil filter and gaskets. If you have a carburetor i would change it or rebuild/clean it up. you dont know how long it been siting with old gas. same goes with gas tank . clean it up of all the rust in tank and put POR15 Fuel Tank Sealer https://www.por15.com/POR-15-Fuel-Tank-Sealer

I had a 350 rebuilt it came with all the gaskets and new timing chain . the other stuff i did on my own because i do not wat to put a lot of money into a engine for it just to overheat and warp the engine. Chevy is well know to make engine block out of metals that warp easily
