Boise Chall OP mopar B Joined: Jun 2009 Posts: 659 Boise Idaho	How can I ID a 73 Satellite/ Roadrunner Big block K frame. I have one Satellite that came with a 318 and was an all original car so I know that one is a small block K-frame but my parts car which is also a 73 Satellite Has a 440 in it but I think it was a factory small block car. Is there an easy way to tell a big block K-Frame from a small block K-frame. Pictures would help a lot thanks for the help.

I have a 73 that had a 440 in it but it originally had a 318 in it. I remember my dad telling me that he put a kmember out of a BB cordoba in it, but like I said, I had a guy tell me that didn't make sense because they should have been the same.

Without knowing what too look for I can't tell any difference between the K-frames. I did notice that the car with the 440 in it does not have an oil dipstick and I can't see behind the the motor mount to be able to tell why. Did all 440's have provisions for a dipstick on the driver's side of the block ? I hope so as I plan to use this motor in my car.

There is a difference in the K-frames in 73 and later BB vs. SB engines. Sorry I don't have pictures. One way to tell a BB car is the passenger side inner fender is different. The small blocks had a full inner fender and a small access hole for the UCA adjustment bolts about 6" across with a metal plate over it. The BB cars had much of the inner fender removed from front of the UCA area to the firewall and from about 1/2 way down to the bottom. It was covered with a large rubber mat.

Fast forward 5 years and the guys on Moparts tell me I did it wrong. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon

I used to have pictures saved a couple of computers ago. This topic seems to come up every so often, and theres always a debate over if there was a difference or not. Not to say you can't put a big block onto a small block k frame. However, when I tried it in high school, I had some alignment issues....

Looking at it, everything looked fine. My girlfriend (at the time) pointed out that the engine was crooked, and she was right. Not alot but enough to cause issues. My fix was to lop off the drives side mount and move it back about an inch to correct the problem. My understanding is that the pass side might is in a different spot too.

Another easy way if the car is still fairly intact is see of the passenger-side fender is solid, or has the rubber mat covering an opening in like in the picture above. Small block cars did not have the open fenderwell. Another way... do you have the VIN? The Blue Goose My instagram: Bossride

But if you don't know any better and just go ahead and do it will work fine. Sure you can do it but the trans won't bolt up in the crossmember that why there IS a BB and SB K-member. I tried 20 year ago and couldn't get the mounts to fall in and ended up plasma cutting the mounts off and welding BB ones on....Everything lined up fine then. I couldn't imagine getting one in and driving it with the tail shaft of the trans pointing towards shock... Oh and the easy way to tell whether the K-member is a BB or SB is that BB are straight across and the SB mounts are staggered in appearance when looking sideway at the K-member....

I hope to have this car back together for my son next summer and it hasn't had a motor in it for 20 years. Like I said, this is an original SB car and I remember we had a BB in it and I disticntly remember helping my dad change the k-member with the motor in. I guess things weren't lined up right and someone told him to get a kmember from a cordoba and we did. I have no idea what motor mounts to use or what they look like. 6349872-100_2249a.jpg (505 downloads)

If you are planning on running headers you will need to trim some of the inner engine pan on the RH for tube clearance atleast I had to with my hooker super comps....

What is funny is the guy that did the body work and paint fixed that exact spot as my dad had it all kinds of cut up holes punched and so forth. Bummer. Where in that pic should I cut it? Thanks a bunch and didn't mean to hijack this thread.
