A oil pan question
Hey Guys,
Haven't pestered the old pros for awhile but got a question. A friend of mine purchased a "good" B engine for his 31 with one catch. No oil pan. He has plenty of A oil pans but oh well. I seem to recall that someone had a show and tell on modifying an A oil pan to fit the B engine. Does any of you folks remember what link or publication this came from or am I just having a senior moment. Thanks for any help! Peter |

Re: A oil pan question
Hi Peter,
Just one (1) "simple" suggestion. 1. If your friend could find a spare A flywheel cover, first, just remove the B flywheel cover. 2. Then, install the A flywheel cover, which will easily fit a B engine with no absolutely modifications. 3. Next, with an A flywheel cover, your A pan(s) will absolutely fit both the B engine block and the A flywheel cover. 4. No cutting ..... no welding ..... no valuable time loss ..... no four (4) letter words. 5. Also, a B starter motor will also fit the A flywheel cover; and an A starter switch will fit a B starter. Hope this helps. |

Re: A oil pan question
The A pan can be enlarged to fit around the B rear main cap. Best done on the bench so you can see what you are doing. By using ARP 8-point nuts on the B rods, they will clear the sides of the A pan. PM me and I'll send you that chapter of my Banger book.

Re: A oil pan question
Thanks guys. Jim, what I neglected to say was that it has modified pistons (283's) and rods. It's the allen bolts on the rods that don't clear as you pointed out. I wonder if you can heat and possibly hammer out the bulges like on the B pan?? The enlarged rear main isn't a problem.

Check out my past posts for pictures, etc that you mentioned ! My B pan had been mutilated by past owners, till it was not usable. A buddy here and fine engineer type mind (ZZlegend), devised some rough tools from bits of steel. We used his ideas/tools and torch heat and small grinder to make bumps to mimic B pan bumps, and to enlarge rear main bearing area. It was done on an idea from Jim B book and came out GREAT and looking like factory made ! BTW..Do not overlook the suggestion to use the ARP 8 pt nuts ! I used them, as they grip with MORE threads than old stock nuts and are of modern hardened steel ! Last edited by hardtimes; 06-09-2016 at 01:40 PM. Reason: ........... |

Re: A oil pan question
Post number two suggests using a Model B starter with a Model A starter switch on the project. All the Model B starters I have seen use a three screw pattern to mount the switch vs the Model A starter using a 4 screw pattern. It is not a routine easy swap.
