Good morning gentlemen, found this site doing some tech research over on the HAMB and figured I'd join up.
I'm building a 27 ford roadster on a model A frame, 41 ford underpinnings, Y-block and a 5 speed (got a freeway with 80 mph speed limit as part of my daily commute).

Very early in my build right now.  I don't have my y-block yet, and honestly am just looking for a good core block to use for mockup in the short term.

My first Q for you guys, will any Y-block from an early 239 up to the later 292 be fine for mockup of mounts and trans position, or are there mounting differences between the years?

Looking forward to digging through all the knowledge here.



Looking for 292/312 block in Southern Utah. 90 min from Las Vegas.
