Four bolt mains; check! Looks like you have 351W heads with adjustable rockers and pushrod guides. I'm pretty sure the 351W heads never came that way from the factory. So, your heads have been modded. Hopefully, they've been ported as well. A Boss 302 short block with factory 351W ports would be OK, but not great.

It can't be a complete 302 HO rotating assembly because the stock pistons don't work with Windsor heads. It definitely a nice block and the heads have been modified. But without taking them off, we don't know a lot more.

I wonder what pistons are in there.

They have to be Windsor style pistons.

Yes, I know, but wonder what compression.

If you have the intake off you can see the head casting numbers with a mirror held in the lifter valley....the casting numbers are under the intake ports.

Probably flat top pistons. They work well with a 60cc CC. But unless he takes the heads off . . . .

 

[supershifter2]

you should pull a head and see what the pistons are and check the stroke. what size are the nuts on the connecting rods ?

I ran that same set up for many years. It was cool stuff.....in 1971!

Nowadays we have better parts available right off the shelf. That said, set up right - you could make a very nice running SBF that would be a lot of fun.
