I would like to build up a new shortblock for my 1970 440 Six pack (Super track pack) Super BEE and keep the factory exhaust manifolds and six pack set up.

I was thinking to build a 4.250 stroker bottom end with 2.20" rod journals and have a decent set of 906 heads to run.

Any advice for staying pump gas and no headers?

Have a fairly good budget to work with, but want it to look stock externally and hopefully run 11.50's at 4,000 DA

Ideas? I know that cam selection will be critical with the HP manifolds and pump gas...

Cheers,

Arnie
