Eddie used O E pushrods when we built his 340... They made them and shipped in less than a week and the custom ones were lower cost than some places sold pre-made ones..
Yeah and he's only like 10 miles from me.. i emailed on sunday and hadn't heard back. and called this morning and no answer... called smith brothers. 2 week wait but they will show up. that OE is like 1/2 the price if they are decent though
