Hello, i'm ian from Malaysia..
Sorry for the questions but i have search all around and takes me no where..Currently i'm on my project rebuilding my RB20 to RB24..and the prob is the stock connecting rod clearance issue..i have source out for info and few told me that after market RB25/26 rods such as Eagle will fit into RB20 blocks give u clearance around 2-3mm(??) or is it any after market rod will fit without any issue??regarding the photo given,the bottom block was cut, but this is for using with Eagle rods right??is there any measurement that i can refer to cut the bottom block since i'm using stock RB25/26 connecting rods..
sorry for my English..
Cheers..
