"Digger" Dave Molnar sonic tested the block he chose..
Originally posted by PackardV8 View PostWhen the 289" is bored .060", the displacement is 298.885". That was how the prototype R3s were created. The production R3s were overbored .093" for 304.5", so, if we're beginning with a 3.656" bore +.060", we're up to 3.716" bore for 314.5". That will require sonic testing. Many full-flow blocks won't take that much overbore.

'49 Oldsmobile - 303" grew to 394" by '59
'51 Chrysler - 331" grew to 392" by '57
So yes, the Studebaker V8 started small and stayed small.

What Mike said!!!! The cylinder wall is thick but not infinitely so. .080 is the max. My Packard needed to be bored and they went .040 which increases displ to 296cid. I think their 304 was .080 over. The Stude V8 is square (bore essentially equal to stroke) If you were to increase displ. you'd need to mess with the stroke and you'd end up with an under square engine. Guess free advice is worth what you pay for it. formula: pi x 1/2 bore squared x stroke x number of cylinders = cid

The following are offered only in the interest of accuracy.
When we routinely work to .0005", giving and getting the dimensions is crucial.Originally posted by Jeffry Cassel View PostThe cylinder wall is thick but not infinitely so. .080 is the max.
On the other hand, we regularly bore pre-full-flow blocks .117", for 308".

Regarding the pre-full flow blocks, is it possible to drill and/or otherwise modify one of those to accept a full-flow filter, possibly remote-mounted? I know I was able to do that with an early OHV six.Gord Richmond, within Weasel range of the Alberta Badlands

JMHO, but when beginning with a freshly cleaned and rebuilt engine, especially those with a closed PCV system, there's very little advantage to a full-flow filter system.
Mike and I will probably have our debate again here. On pre-full-flow builds, where they're not being converted to full-flow, I find definite advantages to retaining the partial-flow/bypass filter system and he doesn't.
