How much is being "RIGHT" or "correct" worth? How much power? How much longeviety? How much more right can my extra money guarantee? How often do manufacturing standards allow for a "standard" deviation? You may pay extra for "Ford 1.73 rockers" and get a BBC 1.7 just because most people dont check their rocker ratio before they install and the MFG can get away with it until someone calls BS on them... Being "right" isnt worth my extra money personally...I plan to buy a set of 1.8 ratio rockers down the road, if i can confirm that they wont detonate upon instalation that is...and guess what...they dont make em for a 400 ford...so far as i know at least...
IDK if anyone has measured them, i couldnt afford to buy two sets and measure them myself...return shipping alone would cost you 40 bucks if you wanted to measure the difference in two new sets right now, and then send them back...maybe theres and engine builder out there who will chime in with out a biased opinion and just present facts...I have only two facts at my disposal...They are listed as interchangable at a certain price point...and I have them on my running, very strong engine right now. Anyone else have any facts to present?
