I’m trying to decide what engine combo to run in my 1987 Chevrolet dually, which still has it’s original big block under the hood. It’s down one cylinder thanks to a valve that’s tuliped or a seat that is bad, so it needs some love for sure. I’ve considered several different big block combos, but these videos are certainly helping me out on the decision. I am leaning towards the 454 or mild 496, but I think I’m going to do heads, cam, intake, etc on top of the stock shortblock to start. We’ll see. But I do believe that boost is in my future. I mean look at this! Or should I do a ProCharger on it? What do you think?

Video Description:
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 6-71 BLOWER.
