Reply With Quotetim need to know valve events on cam spec card example; BTDC 27 ABDC 63 BBDC 63 ATDC 27. Do not give them to me at .050 . and I will run it for you.
To all you desktop dyno experts,
I am finishing up some upgrades to my 460 BBF and wondered if one of you would be so kind to run my setup on DD? Here's the data
1) 460 Ford, 2-bolt std bore
2) Forged 8.25 to 1 CR pistons
3) A3A closed chamber heads with stock valves (I think the In is ~2.07 in., Ex is ~1.6 in), exhaust ports cleaned up (mild porting)
4) Hydraulic cam Intake 230 deg @0.050", 0.553" lift, opens 0.050" at 5 BTDC; Ex 224 deg @ 0.050", 0.532" lift, 114 deg lobe centers
5) Twin pull through turbos (Rajay T-300 I think) w/log exhausts, boost limited to 10 psi
6) Single 750 Holley, Vac secondaries
7) intercooler (60% efficiency guess) and water injection
Let me know if any other info is needed,
Thanks Tim

Turbo,
The card didn't have the exact numbers at 0 lift, so I backed into these from what was on the card (274 intake duration and 270 exhaust duration at .006" and .050" numbers(5 BTDC,45 ABDC,50 BBDC,-6 ATDC) on the card. 27 BTDC, 67 ABDC, 73 BBDC, 17 ATDC are the values you asked for. Thanks Tim
Turbo,
The valve sizes are 2.075" and 1.646". Tim
