    I just got to looking at my so called 465-205 out of a 77 chevy that was put in my 68 burb but the more i look at it it looks like a 420. a huge heavy cast bellhousing, the shifter is taller then the dash is...

    wait didn't the sm420 have to have the bellhousing bolted to the tranny side 1st then the motor cause of the threaded holes were on the tranny side not the bellhousing side??

    one more thing, it has a bottom inspection cover lke an auto would have, not the front half round cover like most 465 i have seen.
    but then again could they have used a 465 on a 420 bellhousing.

    was a 420 ever offered with a 205, that part i can ID as a 205,LOL

    *** another project , another round of being the newbie,LMAO****

    You are partly correct on the bellhouse removal and bolts theory. Yes the bottom two bolts do go into the tranny from the motor side of the bellhouse on the SM420 but you don't have to pull the bellhouse as the bottom inspection plate is large enough to get the bolts off from the bottom.

    If you think pics will help I have a couple SM420s on my spare parts rack and atleast one has a bellhouse on it. All are 2wd or divorced and as far as I know only the rockwell tcase was ever mated by the factory but I could be wrong.

    Oh yeah, 420s only have PTO covers on the drivers side. 465s have them on both sides.

    And 465s all have reverse light switches where as only the last half of the last year of 420s do so pretty much they don't.

    sweet, that'll help. if it's a 420 i'd love to put it in my jeep with the 7.2 to 1...yummy.

    great i was hoping for no snags on this build, I just wanted a basic daily driver that looks nice and can tow... don't need 7 to 1 in that....hhhmmmmm

    yah, the SM420 is awesome in the jeep but I don't think it would be of much use on the road. Then again the Sm465 really isn't that higher in 1st, probably pretty useless on road also.

    I have a 420 in my jeep and I am building a jeep for my wife that will have a 465 in it. If I didn't have 5 spare 420s I would probably go to a 465 in my jeep just for easier spare parts.

    The 420 case is also shorter than the 465 case.; 10.5" vs. 12" according to AA's page.
