questions about different block
One of my friends said he could sell me his 350 block for a really good price. It's from an 80 something truck, and I was wondering if it would work with all the sensors and etc. on my 86. I know you could make almost any chevy engine work in these cars, but I don't want to modify too much.

The only sensor in the block itself is the knock sensor. All the rest are in the heads and the intake manifold. OK purists, the O2 sensor is in exhaust but it is unchanged with a block swap.

I am having a serious brain fart right now but I can not remember the year changes for the 1 or 2pc rear main seals. But if is not the same as yours you will need to make some changes if I recall correctly.

Oil pressure and oil temperature sensors are in the block. They are close to the same locations in the early and late blocks.

It will work in your car. the only problem will be how much money you can throw at it.
If you currently don't have a 1 piece rear seal, use your old pan. If you do, just get another one locally at a junk yard off of a 75- 80 corvette.
oil pump pickup is different but oil pump is the same.
A used short block is usually in the $75-$100 range. a short block that is useable with no work is about $150-$200
I bought one for the pickup for $75 and it was a 4 bolt main. I bought one at a wrecking yard for a friend with forged pistons that was useable for $150, 4 bolt main, with a cam, pan, harmonic balancer, oil pump, timing cover and had roller timing chain. It is still running fine 2 years later. We bolted stock vortec heads on it with better springs and a vortec air gap , changed the cam, and it's a killer engine.
