    5liter, whats your H/C/I combo? Cause I made 434rwhp with 7psi, a 10.8:1 A/F and conservative timing. Stock pullies and a powerpipe. Do you have a 1 belt or a 2 belt Novi? Ran 11.77@117 leaving the line at ldle. I then stepped up to 10 psi(no dyno #'s) and went 11.28@123 leaving at 2000 rpms.

    FWIW if you set up a conservative tune @ 7-8psi, with high quality parts and a stock shortblock with no issues, it will last a long, long time. I should have my head examined for even pulling mine out last year.
    89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:





    Although I am collecting parts for a 12.5:1 393 :D

    I believe both the single and the twin belt set-up's share the same 3.54 step ratio (internal gear ratio)...........so yes the output variables will be equal depending on pulley diameters.

    I'm still using my stock crank pulley....I might switch to an 8" crank soon, and possibly 3" blower ( I just hope I don't overspin the blower). With that I should see close to 14#.

    I'm not too familiar w/ the 1 belt system, so I don't want to givfe you wrong info. Sorry.

    No, I have a custom made 8" ASP crank pulley and a
    3" S/C pulley, a 4" power pipe and a 80mm mass air meter.

    I'm not really sure.........but I know its not a low 11 second bike.
    I ran my friend who's on my bike and is a very good rider 6 different ways with me in my stang and I beat it all 6 times. We tried from dead stops and different rolling speeds.
    Then he wanted some with his 01 GSXR600 and I took him also.
    But my other buddie with a '01 NINJA ZX-7R (which is a 750)It has a cold-air intake,sprocket and slip-on muffler......He got me ! :(
