Krom,
Just to elaborate..I put a set of 300cc intake runner heads on an SB2.2 that was a 4 inch stroke with 6.250 rods.I rented it to the Morris brothers over in Murphesboro,TN. Tony said it was all the motor anyone would ever need on a dirt track.It made 875hp and 710# of torque on Custom Race Engines Dyno.
