not that I can help with initial settings....but aren't those injectors awfully small for a 468" engine with a turbo?? Hell, without a turbo, that would be border line....

Yea...... just the basics, roughly 32 * .8 ( max duty cycle ) = 25.6
25.6 * 2 ( figuing .5 BSFC ) = 51.2 HP per cyl,
51.2 * 8 = 409 HP total.
this is a crude calculation, but shouln't be too far off if I rember it right.
I think depending on boost 45-65 lb/hr would be in order. unless of course you are going to use 16 injectors and stage them.
Joe. but it sure sounds like a cool project

more like somewhere between 45 and 120 lb/hr (with that many cubes, there is a hell of a lot of HP potentional depending on how the engine is set up)
Definitely interested in your project also. Big cubes and turbo's are a match made in heaven.
