Fast makes the biggest that i have found so far drop in injectors for 8.1 85 pounds. I am now in possesion of a raylar intake since my truck dynoed 430hp to the wheels with stock intake, stock tb, stock maf, and stock injectors. running at 122 % duty cycle at 5000. I will do a dyno comparsion of both my self made intake and raylars with everything else being equal and bigger injectors.

Also anyone bought any of the dart stuff?

What kind of fuel pressure are you running to get 122% duty cycle? What was the A/F ratio?

These heads made 600hp(dummied down to 590) and ran on one of the bat boats in 06. They used the stock intake manifold and I believe a modified airvalve.

The iron eagles will flow more air with a 2.3 valve, very close to 400 cfm @ .700 lift
can someone get me in touch with Jim V

Default 496 Dart Update

I have been thinking about upgrading the single 496 HO in my boat for next year and gave Tyler a call. He has a 496 new Dart head, cam, ECU package that puts out around 575hp n/a. I will let him chime in here on details if he so chooses.
