Default 2400 vs 2800 converter

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.

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

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