I just recieved feedback from a client in Canada with a 70 torino C6 weighing in at near 4000 pounds with driver. Low 13's at 107 MPH with traction issues. This works out to over 450 hp at around 5,000 RPM.
I am posting this because I was surprised by the output given the simple straight forward engine build. We built this last year.
460 inches with trw domes at 0 deck.
RHP D3VE castings with small 2.08" / 1.65" valves, budget port work, 305 / 182 cfm @ .600" lift. 30 degree back cut on both intake and exhaust valves.
Factory bolt down rockers. Final static c/r is 10.3 to 1.
Voodoo 219/227 hydraulic cam ground on a 113 lsa in at 109 icl due to high static c/r.
RPM intake and holley 750 DP
Summit high volume fuel pump.
Hooker headers and duals with X pipe
Duraspark dizzy 14 initial and 38 total in at 3K with MSD 6 al ignition
I paid specific attention to good low and mid lift flow rates given the modest .540"/.552" valve lift.
There is nothing really special about this combination. It is easily duplicated. I really believe the key is just a well matched combination of parts working well together.
Thought I would post this here for reference Dave.
