Model A 3.25 vs 3.54 Gear
 

Question,
I know what I prefer on a V-8 but I am curious on a Model A. I am building a inserted A motor for my Victoria (.125" over and a stipes 340 cam). We stock and sell both the 3.25 and 3.54 gears. I was intending to install the 3.25 gears, but will I regret it? We live near some hills but nothing to big.

Thanks

Mike, the only thing I would suggest is that cam may be giving up a little low-end torque when compared to the IB330. You might want to talk with Bill or Tony in that regard if you want to use the 3.27. Outside of that, I have installed them in customer's Fordors and they have toured well in our area. Most of those engines were 6:1, oversized intake valves, bowls opened up, and a IB330 cam. I think you will be happy with the 3.27. While you may not be able to pull that mountain over by Sewanee University in high gear, it should go up it in 2nd with no big deal.

On a side note, did your guests from Mass make it to your place yesterday afternoon??

Brent,
Thanks! So you'd prefer a 3.25 over a 3.54 in my situation?

Guests you are refering to did stop in briefly yesterday.. I don't have near the opoeration in which you do LOL

So, what is the difference between a stipes 330 vs a IB330 cam?

Curious minds want to know.:confused:

IB330 is a Stipes cam.

I have installed both rear end gear ratios. In our 1929 two door sedan and our 1930 Pick up. Climbing hills, the 3.25 ratio will work great when there are only two people in your Victoria. With four people, it will be a little more sluggish in the hills. In our Pacific North West, we have 10,000 ft high mountains and with two people aboard, it is no challenge at all for our 3.25 ration in climbing. The 3.54 ratio in our 1929 Tudor is just fine for hauling 4 passengers up a mountain. I have well tuned stock engines.

Fortunately we don't have the 10,000 ft elevation to contend with! But in all fairness to a Model-A engine, if you figure a Vicky weighs about 2900 pounds with 2 passengers aboard, -and when you add 2 additional passengers, you are increasing the total weight by about 15%. I would think that is a justifiable reason for it to be a little more sluggish. :D http://www.model-a-ford.com/LOL.gif
