I have a Crane solid cam .570/.590 @.050 with 246/256 duration @.050. It has a 108 lobe centre. I have closed chamber heads with TRW flat tops. I want to know where my peak torque area is? I will get to a dyno someday! I'm guessing somewhere around 4800-5200rpm.
Thanks,
Brian

I found the funnel web test. The cam is very close to what I have.
Thanks,
Brian

The Brooklands 351C book of old Hot Rod magazine articles has a dyno test
of 351C with that Crane cam. The engine was built by Chris Kaufman for a
Pantera and was tested with a Holley Strip Dominator with a 4 barrel and a
Weber independent runner EFI with 48 IDA's. When I was living in California,
one of the local Pantera club guys had a 351C with Webers and the same Crane
cam. The independent runner intake really tamed that cam. It was quite
streetable. 48 IDA's are on the small side for a 351C but the Webers still
pulled better HP than the Holley that was tested. With today's race carbs,
I'd bet a single 4 barrel would do as well or better on peak HP but won't
pull nearly as well in the low and mid-range. Here are the details from the Hot Rod article from my 351C database: Carbs
