My Rob Loring 452ci engine had the 'raised ports back in the 80's.

5/8 inch flanges and the ports raised by 1/2 inch with directional runners.

Engine made 550 hp and ran in the nines with a street Dart.

Very trick stuff indeed for the ERA!

Carpe diem, quam minimum credula postero, thanx Horace!

There’s no point trying to fix stuff that ain’t broke,,, 'but if ain’t broke',,, you is not trying hard enough...
