Dual Plane vs Single Plane --Sorry Long Post - 11/21/09 08:17 PM
Kinda slow today been doing some thinking. I run a 410 stroker small block. It has edlebrock heads that other than valve springs, retainers and milling to 59cc's hasn't been touched. I have been running a M-1 that has some port work. I run a solid cam in the .555 lift 296 dur area with a lobe cent of 108. I have been shifting at 6600 and tach at 6900 in the quarter. I have been worried about the cast crank at these rpms and since the engine peaked at 525hp @ 6200rpm on the dyno maybe I'm twisting her too tight. I have a dual plane that is supposed to be good to 6500 rpm and I doubt the heads flow much more over than anyhow. Would I be ahead shifting at 6200 and running the dual plane and my 4.10 gears back in? I am running 4.56's now with 29.5 mickeys. Car runs good now I'm just concerned about the Eagle cast crank.
Thanks
