Here is the new lump for my 69 chevelle. 6.0L long block, LS9 cam and springs, all ARP hardware, ported LSA blower with a ZL1 lid, 80lb injectors, 9.10" lower pulley, 2.55" upper with 1 7/8" headers. The blower will be pushed to 36% over or about 16lbs of boost. I will be adding methenol injection because we aren't lucky enough to get E85 up here.
