Thanks guys,
I have a RHS tall deck in an Art Morrison frame with tony Wooward rack.
The engine is a 440, mast motorsport black label heads with a Ozmo twin throttle body manifold, it's has a solid roller cam, I'm not sure of the spec's.
Projected Hp is 700 - 720 at the flywheel.
I have been mocking op the headers today using the Icengineworks system, there is not a lot of room on the drivers side. The tube is 2", and the shortest pipe is 24" to the very front of the collector.
All help is greatly appreciated.
