Ford Model A & B Motors
Looking for some information on Ford A & B Motors.
1 -- Will a 1939 Ford top loader trans bolt direct to the A or B block? 2 -- Is an adapter needed for this setup? 3 -- Who sells rod & crank insert bearing mod kits for these motors? 4 -- Who sells HC flat top pistons for a hot rod motor build on A or B? 5 -- Does any one sell a HP kit for these motors? Thanks in advance, my first Ford A motor build |

Be sure to also ask these question in sister site to this one "H.A.M.B." if you have not already done so.

Re: Ford Model A & B Motors
#4 isn't really possible for the Model A and B, but a head will give you more compression and power.

Re: Ford Model A & B Motors
MikeK -- After reading your information it sounds like a HP flat head is called for. With the same piston setup and a HP Flat head what CR range would I be looking at?
I do not want the cost of an OHV setup. This is my first build of an A or B motor after 40 years of BBC front motor dragster fun. I am learning as I go. |

The first question you need to ask is how much HP do you want to make? While there are knowledgable people here, this site leans way towards the stock Model A. The absolute best place for your questions of HP, in my opinion, is the HAMB forum.

Re: Ford Model A & B Motors
Your off to a good start, maybe you can get one of Tod's new heads, search the threads
here. Also maybe a Stipe 330 or 340 camshaft. See what others chime in with. |

Re: Ford Model A & B Motors
Hey old28,
Regarding intake and exhaust valves. You can get benefit/improvement from enlarged INTAKE valves. However, you do not need to change the exhaust valves as they will do the needed work as is. So, save $ and leave exhaust valves as Ford made them. Last edited by hardtimes; 04-11-2016 at 12:50 AM. Reason: ............ |

Re: Ford Model A & B Motors
Dodge -- Do you know if a 330 or 340 camshaft will make 75+ HP? New to this forum, who is Tod"s Heads?
hardtimes -- That good news on the exhaust. Do you have a intake size in mind for my HP range. |

Re: Ford Model A & B Motors
What are your objectives here? You will be dissapointed in some aspects of a build like this simply because of the design of the engine.

In the attached picture of my latest new build, I've used a B block with 1.75" intake valves and stock exhaust valves. B blocks have distinct advantages, IMO, in some aspects and the A block has what is said to be a THICKER deck ...I'm not sure that this is accurate/true after 85 yrs of rust, wear, etc... Here is the BEST piece of info/tip that I can give you to start doing what you are saying that you want (i.e.-figure out what block to start with etc). Get and study a book written by a senior senior ...member here ! This is written information for beginners and for those familiar with the subject. It will answer many , if not all, of your inquiries. I used the guidance of this book to build the B that you see here. After getting the 'bugs' ironed out of it, it is a fine piece of equipment/history to listen to. Like Beet Hoven and CCR playing together, eh !! |

Re: Ford Model A & B Motors
Kurt in NJ ---Thanks for the Dyno Sheet tests. A lot of information and combinations. As I start moving forward on this project I feel like a motor in the 75-90 HP range will work well for my project. I am looking at running a 28 roadster with an A motor, 39 trans & a Banjo rear end in the TROG race on the beach at Pismo Beach, CA in 2017.
hardtimes -- What Cam, Bore, Pistons, Head & CR, Est HP in the B Motor? What is the name of the book you are talking about? Thanks for any help. |
