Ive searched, and I havent been able to find a chart or something of that sort, so now im askin ppl who have the knowledge on hand. This question is assuming the block still has its factory supplied crank, not an after market or crank from another block. What is the maximum rod length for a B18 A, B, and C? The reason I ask is because im tryin to get R/S ratio in the right area. So, if there is a variation of factory blocks and cranks with an aftermaket rod set that will get me near a 1.75 R/S ratio (i.e. B18A block and B18C crank with a certian lenght rod) please let me know. If there is write up on this somewhere a link would be great. Thanks for readin.
