CAN I RUN BOOST FOR TOWING? HOW MUCH POWER DOES A LITTLE 174 BLOWER MAKE? HOW MUCH POWER DOES A BLOWN BIG BLOCK MAKE? IS A 496 BETTER THAN A 454? IS BIGGER BETTER? HOW MUCH BOOST CAN I RUN ON A 454? HOW MUCH BOOST CAN I RUN ON A 496 STROKER? HOW MUCH BOOST SHOULD I RUN? DO CNC PORTED HEADS AND A BIGGER CAM HELP WITH BLOWER? DOES A BIGGER BLOWER MAKE MORE POWER? CHECK OUT THIS VIDEO WHERE I RAN A MILD 454 BUILT FOR TOWING WITH BOTH A 174 BLOWER AND A 420 MEGA BLOWER. I ALSO RAN A SLIGHTLY WILDER (BUT LOW COMPRESSION) 496 WITH CANFIELD HEADS AND A BIGGER CAM WITH THE 420 BLOWER. I FINISHED OFF WITH A 496 EQUIPPED WITH AFR 315 HEADS, A COMP ROLLER CAM AND 671 BLOWER.
