340 Cam Duration with High Compression

Seen Crower solid rollers on 108 l.c. 250's in duration @ .050 ,run sweetly on the street in a 340 (4.57 rear 4800 stall,tunnel ram actual 11.7 compression)...
Just something, to think about. ......

I'll second that. I'm running a 254/260 @.050 .638/656 on 108*, 12.4:1, 4.11's, 4000+ stall. Very happy.
