I ahve milled my edelbrock alu. head to have a reasonable
10:1 compression ratio with a 302 CI block. Is it possible
to keep those heads if i stroke the engine to 347 CI?
What will be the new compression ratio? (i am not too
familiar with those calculations) Also what could be the
typical gain with ported aluminium head, E303, and edelbrock
RPM intake?

Oh yes i have an other question in mind...

Why is everybody choosing to install superchargers instead of
stroking the 302? Superchargers are very popular compare to
the 347 CI swap. If I had to choose i would take the 347 crank anytime.

any advice is welcome,

Regards,

Sebastien Cote
