I don't think the length is going to be your problem (if you have any problem at all). The width could be tricky because you have your linkage to add in. My TP was custom fabbed for me, so it might not even be "stock" but you can see the additional room I have even with the Holley 3310 in it (which only has one block). If it were me, I'd just order the carb you want from Summit and if it doesn't fit just ship it back to them.
