Wiseco’s Ralph Johnson called us over to their booth at the 2010 PRI trade show so that we could see a few additions to their product line. Johnson was pretty excited about Wiseco’s new 2011 5.o liter DOHC V8 Stroker short block which uses Wiseco and K1 rotating components in a ERL 95mm sleeved block.  If you’ve ever wanted a 351 cubic inch (5.8 liter) stroker, this might be the right way to get started.

The 351 stroker uses a combination of Wiseco and K1 Technologies stroker components which includes K1’s 4340 billet crankshaft and 4340 billet H-beam steel connecting rods. There are several options in Wiseco pistons for this short block so you can select the compression ratio that suits your needs.
