We all know that Richard has tested junkyard big blocks of all kinds, from various generations of the venerable 454 7.4L, to the newer 8.1L 496. He’s tested them all stock, with camshafts and other upgrades, switching from EFI to Carbs and vice versa, and has also put them all under boost to see just how much power they make. I’m looking at needing a new engine for my 1987 Chevrolet R30 Dually and I’ve been debating about getting an 8.1 to shove in it, so all these torque and power comparisons are super important to me right now.
So check it out and let us know which engine you’d buy for your project.

HOW CAN I MAKE MORE CHEAP BBC PULLING POWER? WILL A CAM IMPROVE TORQUE FOR TOWING? WHICH BBC IS BETTER FOR TOWING? WHICH BBC HAS MORE PULLING POWER? IS THE GEN-7 8.1L AN LS MOTOR? HOW MUCH POWER DOES A JUNKYAD BBC MAKE? IS THE GEN 7 BETTER THAN THE GEN 6? CHECK OUT THIS VIDEO WHERE I RAN A JUNKYARD GEN-6 454 IN STOCK AND MODIFIED TRIM AFTER INSTALLATION OF A MILD CAMSHAFT. I ALSO RAN A JUNKYARD GEN-7 8.1L 496 IN STOCK AND MODIFIED TRIM AFTER INSTALLATION OF A MILD CAMSHAFT. CHECK HOW EACH RESPONDED TO THE CAM CHANGE, HOW THEY COMPARE TO EACH OTHER IN BOTH CONDITIONS AND EVEN HOW THE 454 RESPONDED TO A CARB SWAP VS EFI!
