I'm working on my 65 Mustang...my rebuilt 302/306 engine is almost done (aluminum heads, RPM intake, and other goodies)...but I need info on these stall converters.

I'm going with my stock Ford-302 cam, will have a 3:27 gears installed pretty soon.

I have been googling the net...so I don't have to bother you guys, but I'm still confused...as I'm a rookie in terms of mechanics (a friend is helping me).

My questions:

1. Which converter will give me more acceleration off the block?

2. Which converter will be a bit slower off the block, but will give me a smoother highway ride (like a fourth gear), and perhaps even save me a couple of miles per hour of gas?


I'm looking at these two from Summit Racing:

I'd appreciate a bone thrown at me, I'll eat it, lol.

My engine is a mildly warmed over 351W, probably about 325-350 hp according to my butt-o-meter and when I had my C6 transmission rebuilt I went with a 2400 stall converter. This is about the size that Ford put in from the factory when they wanted a bit more grunt off the line from their factory performance small blocks but still have good road manners.

When you're doing a stock rebuild, it's tough to beat what the factory did originally.

When I started doing my rebuild, I studied what FoMoCo installed in their factory offerings and tried to ape them where I could. Build it like Ford did and it'll be as reliable as an anvil for a long, long time.

 

With a stock camshaft, stick with the stock converter. Rule of thumb is to determine the power range of the camshaft being used, then use a stall converter that will just fit into the range. If, for example, your camshaft has a power range of 2200-5800 rpm, use a stall converter just larger than the 2200 number. Anything other than a standard stall converter is going to compromise your economy and won't really give you any more grunt.

As for the rear gears, I don't know of anything in the 3.27 ratio that will fit your rear axle unless, perhaps you have installed a later model 8.8" rear end. You will have 2.79, 2.80, 3.00, 3.25, 3.40, 3.50, etc.

 

the power you are making is actually gonna determine the actual stall...

 

340 HP.

Thanks for repying guys, keep them coming!

 

If you fill out a short questionnaire, TCI transmissions will help you make the correct choice.

Thank you, I'll look into it.

 

Yeah, don't put a high stall on a low rpm cam...I bet the stock cam runs out by 4800.

 

We are in the process of solving the problem, thanks guys.
