Re: HiPo 289 question
If it is a hipo motor,it will have a C4 or a C5 number at the start of the part #. A hipo will have bigger rod cap bolts[it will take a 9/16 wrench to fit them.They are worth a little $$.If it has the correct heads,it will have the # 18,19, or 20 on the corner of the head..let me know if you still have it.
