any numbers yet?

Not yet it'll be tomorrow or friday,

My guess 1068hp and 852. I said 1050 when I went into it so anything above that is a bonus.

Motor Dyno. Advanced Product Design (APD) is doing the engine and they have a dyno in house also. Going to also dyno it with their new alky carb.

Just getting in from the garage. Want to say what a treat it was to deal with APD on this entire engine build. A lot of knowledge of cams and head work.

The results
Peak HP 1032 @ 7300
Peak Trq 899 @ 5800

Average HP between 6200 and 7300 rpms 1018
Average Trq - 793

M5 Alky it peaked at 1049@7300

It made a touch less peak then we thought it may but in the same not 1032 peak and 1018 average it was a very good combo all the way through. I have it in the car and almost ready for the track tomorrow afternoon.
