Re: 48 Pan Hot-Rod motor build ...
It's 88 inches at the moment ...
4-3/4" stroke and .040 over on the FL bore of 3-7/15"
Thinking about going to 3-13/16" bore, that will get the cubes up to around 109" with the stroke that it has now ...

Sounds awesome. Didn't know it was possible to go that high in cubes on a panhead engine. Can't see the picture.

The cases are after/market, made by STD .... These are made Heavy-Duty with a world of deck meat...
They would have no problem supporting that large of a bore ..
Stock heads was going on the shelf being we found a set of STD's (Shovel ports) to mate up with the Big Bore jugs...
...... But ......
After doing the math ... $$$ ... It's adding up.
We have a few other irons in the fire..
Up-grading both shafts, going to go with the Timken bearing and the 58-up pinion shaft...The case was made with this in mind...
Up-grading the stock rods to H-beams.
Owner decided to keep his 4-3/4" stroke and just beef the crap out of the lower-end ... No Big Bore in the picture....
Keeping the 1948 heads in play also.... Will be going to a oversize intake (.125") just to help feed the 88 cubes that it's going to stay at ...
