Valve springs came with the heads. As far as what do i want for power....what we all want....the most power for the least cost. Seriously though, at this point, the cam swap was such a pain that i dont think i can stomache doing it again. So assuming that the cam stays the same, seems like my only options are to get a larger intake, ie rbox, victor, etc. and a larger throttle body as suggested before. I love the sounds of the engine now as opposed to the bigger cam i had previously.
When engine was on engine dyno, carb, bigger cam, it pulled 460HP/450 torque. Considering drivetrain losses of 25%, it seems like my current numbers are not too far off what i would expect.
Not to make this more confusing, but when i bought my computer from cardone, i ordered one for a 93 cobra...not knowing what i was doing. The computer is painted black with no stickers. the invoice says it a 93 cobra #E9ZF-AA computer. Soooo, since my MAF is programmed for an a9l and the tuner assumed a9l in his tune, i wonder if it actually being a cobra computer would cut the power? i bet so. How do know exactly what the computer is? On the
Virtual Shop for Auto Parts, Automotive Accessories and Automotive Tools at autopart.com website, where i got computer, both the cobra and v8 GT computers are listed as 78-4352. Thats what i have.
