| Post subject: | Slant 6 / Small Block V-8 Parts Interchange |
I looked in the obvious location and did not see this listed so I'll ask the question; "what parts on a Slant 6 will interchange with those on a Mopar Small Block V-8?" I understand that starters are interchangeable but I wondered about distributors too. I also see 340 valve springs being used but I'm not sure if this requires mods or not. I don't expect that there are many pieces that interchange but wanted to know. Thanks, - EM |

Small block parts that can be adapted to a slant include solid lifters, valve springs (check installed height), rod bolts, main bearing bolts (make sure they don't block oil passages). The crank snout is the same size as a small block or a big block so balancers can be adapted but may require some machining. The lower timing sprocket is the same as a big block as is the timing chain. The cam sprocket looks similar but has a different offset. A big block Chev also has the same distance between the cam and crank so it is possible to adapt a gear drive from a big Chevy. I have never tried it but have been told that it is possible to adapt main bearing caps from a big block Chev. There are probably more but these are the ones I can think of now. |

Alternators interchange, and the 318 BBD can be made to work OK on a slant. Various bolts will interchange. Distributor housings will not interchange, but distributor internals will. |

Thanks Exner, Reed. Yes, I meant to exclude external pieces like alternators, etc.Sorry, I'm not familiar with your acronym "BBD". |

Carter BBD (Bald and Ball Double) carburetor. It is an external piece, so it doesn't answer your question. Oil interchanges, as does radiator fluid, and I think thermostats, too. |

The oil pressure-relief spring from the big-block is the same. Small block thermostat is the same. The 413,426,440 has the same main bearing journal diameter as the Slant, although I don't know if bearings will interchange. And the starter in my '65 D200 crewcab is the same direct-drive starter used on the 426 Hemi/4-spd cars. |

Starter swaps. Is this for the Poly? PCV valve! Ball and Ball dual |
