transmission fit?

[292farmer]

i was looking at the vortec 4200 inline 6 and came across this site, which as u see the clip i copied states that it shares the chevy v8 pattern, they didnt say the vortec v8 pattern or gen 1 sbc, is their a difference? if not does that mean it will bolt up to the sm465in my 1972 c20? thought it'd be a neat upgrade for 292 inline in it, i looked at a company that will redo the wiring to work in a older vehicle and fix the theft preventative code(think thats what its called cant remember) figured have to definitely custom make motor mounts. and maybe some radiator moving and firewall fitting but i dont see it being to different in size from the 292. anyone see a possible catch i missed in swapping it in?

Individuals swapping these into Jeeps should understand that they share the same Chevrolet V8 pattern, and will marry to a Jeep or GM transmission accordingly.
