  5. EC 228R/236R Cylinder Assembly & Sheet Metal
EC has developed one of the most significant components to have improved modified clone engines: the reinforced racing blocks in 72mm and 76mm bores. The heavy-duty blower housing covers the flywheel and can use EC's 3rd bearing support to add to the block's strength and rigidity. Check our rotating assembly section for the 228R, 236R, 254R, and 263R engines to finish your engine block.
