  • 236 tall block with 86.4mm stroke

    Has any one done this tall block with 86.4 crank combo? if built correct I take it can rev really high?

    In theory yes it can be done. But the oil pump is the problem after 8 k rpm, so you need a dry sump setup for high rpm. Also suitable cams and head work. The difference between a normal and tall block at the same cc will be small. Why chase high rpm? Use the tall block with a TDI crank and you can still rev to 8k on the stock oil pump if required. The extra 15% displacement is more useful than an extra 500rpm?
