Here’s the easy way to get an abundance of power without breaking the bank. Rather than spend your hard earned money on a mundane 350 cubic inch small block, or even a 383 stroker motor, World Products gives you the way to step up to a big 415 or 427 c.i.d. package for about the same outlay as what a smaller engine would cost.
The foundation for this awesome package is World’s new MOTOWN II cast iron block, the most advanced cast iron SBC replacement block on the planet. With splayed 4-bolt nodular iron main caps, it’s fitted with a 3.875” stroke Eagle 4340 forged steel crankshaft, Eagle 4340 forged steel H beam connecting rods, Mahle -20cc dome forged aluminum pistons (4.125” bore) and a high performance ring set. The rotating assembly is internally balanced. A hydraulic flat tappet cam, ground to World’s specs by a leading aftermarket cam company, and a double roller timing chain are also included.
Breathing is handled by a pair of MOTOWN cast iron (Stage 1) or aluminum (Stage 2) heads that have a multi-angle valve job, are equipped with Manley stainless steel valves, high performance springs, Manley chromoly retainers and screw-in studs.
With a nominal compression ratio, these combinations will produce outstanding performance on pump gas, and with plenty of cubic inches at no extra charge, it’s an outstanding value!
