170 for 225 SWAP - '62 VALIANT
VDART, yeah, that's exactly what I'll be doing, if I manage to get that Signet this weekend.
CHARRLIE, back alleys around here are littered with rusty '63 to '66 Valiants (Darts, really), so finding an A-body 225 won't be a problem. I would count on doing a minor engine rebuild anyway - rings, bearing shells, valves, and maybe the camshaft. As long as the block isn't cracked from no antifreeze, condition won't be that important.
