My 360 build.

CC your speedmasters and have various gasket cc's handy
then you can find the right piston to give you .030 quench and the right compression ratio you are looking for
these speedmasters are shaft rockers- right?
those are them in the pic?

from earlier in the thread
Use the build with the least amount of cam and heaviest car weight close to yours.

Re read what Aj said post 6 and update him on the head flows of your speedmasters and cc's and new piston required
lots of good infor in this thread

most guys on this board do not do pro touring or what would you call your usage?
