230 chevy six ?

Went to an older womans house today to help out a friend put on a chimney cap. I was rummaging around her old barn found what looked to be an old chevy six. its a 230. so I asked of course is that for sale. she says no. but you can have it if ya want. great I say.
just goes to show you how helping people out works for both of you.
oh yea forgot it does not have a flexplate. need one if anybody has one.
and will a turbo 350 trans bolt to this. looks like it will. I have some 51 ford stuff I would be willing to trade.

 

The 230 shares the same bellhousing bolt pattern as the small block and big block chevy engines. Your turbo 350 will bolt right up.

 

Good little motor too by the way .
Stock was like 140 HP and 220 ft lbs-enough to get a big old early chevy full size up on plane ...and pretty derned good on gas

 

sbc flexplate will work also

 

The later model Chevy 6s are good engines. I built one years ago, started with a 230, swapped in a 250 crank and 307 pistons I believe, with a head from a 194 with upgraded valves to 1.94/1.50, a cam and dual headers from Cliffords and 3 custom made diagonal intake manifolds each with a stock 1bbl carb. Didn't like to run on cold mornings due to lack of manifold heat. Lots of small block parts interchange. I think 283 pistons work in a 230. And they have 7 main bearings, as opposed to the 3 in a 235. I found out stock rods were only good to about 6500 rpm when i ventilated mine one night. Build it to run good, stick a T5 or 700R4 behind it and you'll be golden.

I'm contemplating building a 230 Chevy 6-banger for racing and have read for years about using 283 or 307 pistons. I would like to see about 10.5:1 compression but wonder how the difference in valve angle and dome location and size would work out using the V-8 pistons with the 6-cylinder head. As I understand it the 6 cylinder uses a 12° valve angle in relation to the block deck compared to 23° on the V-8s. I hope someone has some personal experience using the V-8 pistons.

Thanks in advance.

A friend put 283 pistons in a 230 with a decent street camshaft and had no problem with valve to piston clearance. He also used a Rochester 4GC from a 283 on an Offenhauser intake manifold that worked out well.

 

307 flat top fit right in a 250, but you need to make sure they truly flat top. I bought a set for mine, when I got them open, they had a large chamfer around the top and 8 valve relief. They were more of a universal flat top meant for multiple years of engine and not right for any of them. From what I read, it's about 1 point of compression increase going to the V8 pistons in the 230 or 250.

The block numbers are the same for the 230 and 250, you need to look at the top of the pistons or measure the stroke to know for sure which engine it is. Heads are the same for both engines.
