Brother, it’s the same thing! haha small block & short block, google it up and you’ll see the true hotrodders use the name short block and small block too for the 350’s and 383’s, etc.
even though GM has had a performance division, not much “useful” or good has come out recently…other than the great C6 Vette, namely the Z06 & ZR1, not to mention, the Pontiac G8 or the Original Aussie division of Holden, the legenday Monaro!
