I was talkin with SW on the phone earlier about common sense engine combinations and it occurred to me that he and others might benefit from seeing a wimpy knock-around 480HP in action.
The video shows an all iron 406 with specs as follows:
-Scat forged 3.750" crank
-Manley 4340 6" rods
-JE 4.155" pistons
-World 200cc Sportsman II heads with mild porting and a real good valve job.
-2.055"x1.600" Manley Pro Flo valves
-Crower hydraulic roller with about 230 degrees duration and heavy but indestructable Crower stainless steel roller rockers.
-1971 GM block with Milodon caps
-Compression is about 10:1
-DaVinci 750cfm HP carburetor
-Canton Pan
-Engine is only turning about 5800-6000 in this vid because of track length.
There are two versions--quicktime (be patient) and YouTube Have fun watching
