Early A body Slant/6 to 70's 360 swap

A 727 may or may not clear (tolerance stackup is all over the place on early A's but they are my favs). I'm even seen one that barely touched the pinch weld & another that would not clear with the PW ground down but with that said I would HIGHLY suggest staying with a 904 (lighter/easier fit/less rotational mass). Just me I would get a '66 column shift steering column assy with the '66 rod linkage bellcrank assy etc & a '66 up rod linkage 904 that way you do not have to change/alter anything inside the car. just drill/tap a mounting hole in the subframe to support the end of the bellcrank assy & a notch in the frame next to the hole for the tang to set into (when you get the bellcrank assy you will see what you need to do & it is easy. For power or manual steering you can easily swap the inner shaft into your outer steering column housing to go either way. use the B&M 10239 flex plate to mate the externally balanced 360 to the neutral balanced 904 torque converter. 64-66 273 ex manifolds fit perfect but flow terrible (1&7/8 outlets!) & reportedly magnum ex manifolds fit with some milling & be sure to get the '92/early 93 ones with the ~1&5/16" outlets as opposed to the later ones with ~1&7/8 outlets. they flow pretty good. I would think an early 340 HP passenger ex manifold might fit (it is the best flowing one hands down) & I would mockeup a dr magnum to see if it can be made to fit (it being "the 1&5/16 one" which flows better than the drivers side 340 HP one). the later 340 manis are junk (see eBay for pics). there are 2 pass 360 pans that I am aware of, the "876" which has an ~8" long sump that starts 2" back from a vertical plumb line straight down from the very front pan lip and the "392" which its sump is ~8" long & starts 4" back. they take different pickups & you MAY need the "392". wait for replies or do carefull measureing. EDIT I would get a "champion" alum radiator with the bottom outlet on the pass side so you can keep your aluminum pump & see the dampener/tcover marks on the dr side for easier timing. EDIT meant to say ~2&5/16" outlets on the early mag ex manifolds
