RAISED CAM SMALL BLOCK
World’s NEW MOTOWN II RC small block provides an ingenious solution to a long standing problem. By Raising the camshaft location in the block by +.134 in, World has created a robust platform for big inch small blocks which also upgrades the cam journal to either a BBC or 50mm.
The MOTOWN II RC also features Bushed lifter bores in your choice of .842in or .904in. These upgrades provide exceptional valve train stability at high rpm operation.
Raising the cam location also allows the use of H-beam rods with a 4.000 in stroke crankshaft for greater bottom end strength.
Standard small block style oil pans, timing covers, intakes and other components are used.
Like all World blocks and heads, the MOTOWN II is 100% American made.
This is the strongest Small Block Chevy Block with new Higher Strength Hi-Nickel cast iron and increased main web thickness and front main & cover area.
