Doing a cam swap on my BBC. Would like to get you all's opinion on the combination of parts...
BBC 1970 402 4-bolt block bored out .030 over ( .060 over 396 )
stock stroke
piston dome at 10 to 15cc
piston deck meets block deck at zero
#063 Cast Iron heads, stock valves, 102cc combustion chambers ( may mill a bit )
will be adding long tube headers, 2 3/4 inch tubes
dual plane Edel Performer II+ intake
1000 CFM MSD EFI TBI
will be adding a 1" carb spacer
700r/1800 stall/3.73 posi
compression is between 9:1 and 9.5:1
The cam we have chosen is the Comp xr276hr ( 224/239 Dur @.050, 110 LSA, 1900-5600 RPM: 410HP@5000, 467TQ@4000 ).
A close second was the comp xr270hr.
With this update, I'm looking for a gain in off the line performance ( may need more stall ) and mid range torque.
Fire away please. No parts have been purchased yet, well except for the rocker arms
