289 HiPo technical
I read in George Reid's Ford Part Interchange book that there is no difference whatsoever between a 289 block and a 289 HiPo block. I assume this means no heavier castings around the main bearings, et cetera. BUT, the 289 HiPo block comes with heavier main bearing caps.
From a block perspective, is that correct?
This implies to me the plausibility of either adding heavier caps to a standard 289, or adding a main bearing girdle (plate that ties all of the main bearings together) to meet or beat the strength capacity of the 289 HiPo.
Am I an engine builder? Nope. Would I like to hear from some engine builders? Absolutely.
Am I way off or on track?
