347 questions

I have a 306 in my car and am looking for more power and also looking for expansion later in time. I was considering a 347, is that the same block or is it a larger sb. Is there a link to any websites with info on that engine. Also whats a good price to pay like what have you guys paid for your 347's?

No.

The stroke is different and the pistons are different.

The only thing that the machine shop will do different is notch the bottoms of the cylinders in a certain spot. I did it myself with a jig and a die grinder. The rest of the install is the same as putting any other lower end together.
