Can I put a b cam in an A block?
Is there any problem with this? I have a reground B cam and want to put it in my rebuilt A engine. It looks the same except for the fuel pump lobe. This is my first experience opening one of these up and I didn't notice the lobe until I pulled it apart.

Sure, It will fit just like an A cam.

The fuel pump lobe won't be a problem. You will need to use adjustable lifters. The stock model A lifters won't be long enough. The best lifters are the self locking or sometimes called single lock. The self locking lifters have a larger base where the cam meets the lifter and is very important. I use lifters from Bratton. Page 42 part number 9160 price $71.00 for a set of 8 .

Re: Can I put a b cam in an A block?
The original stock Model "B" cam used a larger diameter lifter than the "A" cam, but with a regrind follow the reccomendation of the cam grinder
I have a stock (not reground) "B" cam in my car, still sounds the same, still same low end power, better fuel mileage and top speed How good a reground cam comes out depends on the regrinder and what the condition of the cam core started with was. |

Re: Can I put a b cam in an A block?
Also does anyone have any input on bronze vs aluminum timing gears? I am going to need to order one as my fiber one is +3.

Get the gears as a set--cam and crank, I have had the alum gear for 40 years, crank gear new at same time, no noise

Re: Can I put a b cam in an A block?
I'm worried about getting the crank gear off. How hard are they to do? I'd be worried about heat near the babbit.

Re: Can I put a b cam in an A block?
Pictures can be deceptive, it's the first car I painted, now after 40+ years the paint is starting to come off the fenders
The crank gear can be quite tight, I have had to drill a row of holes to weaken the gear, then wacked the area with the holes with a chisel to pop it loose---off the car I have a 40 ton press |

Hitch if your installing a Winfield grind even the new single lock lifters may not have a large enough base they were ground for B lifters which were bigger again

I'm running a Winfield super street 3/4 race cam in my roadster and use the self locking lifters from Bratton. It runs good and has for the past seven years.

I've read a few places that the SU-1a is mild enough to be okay.

It is a 280 degree cam. It is designed to run with a 1 inch diameter lifter so you should be ok on that count. A lot of those grinds are running on the street but the gas mileage and the low end performance sure isn't what it could be. |

Depends on who ground the cam
Check by putting Prussian blue on the lifter base and turn the engine over a few times remove and check you must not have contact near the edge of the lifter base |

My engine is counterbalanced and has a lightened flywheel. I have a 6.3:1 head super winfield head and am messing with a bb winfield or a stromberg 97 for carburetor.

The SU1R is slightly less timing at 272. Still too much for street use. (unless you do several other mods) A good grind that will give good street performance and mileage is a 77B. Originally it was ground for the flathead Ford V8. In the 50's it was found to work very well in a mildly modified A or B. It has a stock idle and noticeable improvement in performance.

In any case it would be a good idea to degree it in the block you will run it in. Then you will know what you have. Info on degreeing a cam can be found with a Google search |
