Chevrolet big block
The Mark IV: 396s from the L35 to the L78, the 427 L71 Tri-Power and the aluminium ZL1, the 454 LS6, and a blown 454 for the drag strip.
Chevrolet’s Mark IV big block: the 396 from the L35 to the solid-lifter L78, the 402, the 427 from the L36 to the L71 Tri-Power and the all-aluminium ZL1, and the 454 LS5 and LS6. Every build comes with its gearbox, a Muncie M20, M21 or M22 or a Turbo Hydra-Matic, and there’s a blown 454 drag engine with a 6-71 and zoomie headers at the speed shops.
Its models are made from Jorma Rysky’s “Naturally Aspirated 454 cid V8” and “Blown 454 cid V8” (Sketchfab, CC BY 4.0), cut into parts that come apart on the stand, with our own internals, valvetrain, Muncies, Quadrajet and Tri-Power.
