Typical gain with the 278mm are about .3 - .4 in the 1/4. The 245mm Pro Series is anywhere from .5 - 1.0 depending on how bad you needed a converter. I have sold a lot of 278 for DD F-Bodies with some very satisfied customers. It just depends on what you want.

Just ordered my second "4C" converter from Chris....this one being a little more loose than the first per my request
The last one I bought replaced a Yank SS3600 and I can tell you that the Circle D is HANDS DOWN a better converter for around town than the Yank was.....I won't buy one from anywhere else for an f-body

278MM Circle D !!! I purchased a 278 mm 3200 stall from Circle D and had my ace LS1 mechanic Bad Chad install it friday night. The car has been transformed from a Dawwggg in low gears to a screamer and it is most definately quicker all thru the gears. I was afraid to get toooooo much stall so I purchased the 278mm and it is perfect for a street car IMO. The laziness is completely gone from the stock drivetrain. IT Screams now and i haven't tuned on it or anything yet. It is tight but you very well know it is in there. Perfect for a DD or somebody who doesn't want a loose stall to ride around in. A transmission will probably be in my future because I have been running the heck out of it putting a big smile on my face every time I launch that thing in low. GM should have put that stall in the car from the factory. It is a night and day difference but not too much==Perfect I would say!!
I was hard headed and didn't listen to those who said do the convertor first but now I think they are right.....I KNOW a billet convertor would be quicker and better but honestly I didn't want more stall than this and after driving it I am happy with my decision mainly because it isn't a race car but a mostly stocker you can drive anywhere with good fuel economy,, good times radio playing with the A/C ice cold and run in the 11s.

Just a quick thanks to the LS1Tech members for all the converter orders. We have been very busy lately because of your support. Here are a few pics of what I am doing this weekend. I am making some more billet covers for the LS's. I am making single disk and multi disk. I can now make a multi disk for the 4L80 if it fits a LS style flex-plate. I will have a 4L80 6 lug direct replacent soon.
Chris
Here are the fronts and they have had 2 operations done already, there is a total of 5.
Same bench, different angle.
This is what the blanks for the billet pistons look like, they will be machined next week.
This is a multi disk halfway through the 3rd operation.

Here are a few pictures of the Billet Street Series - Stage I.
A cool layout of the converter.
This is inside of the billet front, You can see the bearing I add to properly support the turbine and setup clutch clearance. This is a Circle D upgrade, other billet converters have nothing here.
This is the outside of the billet front, this is the main difference between the Stage I and Stage II. The Stage II is a much stronger front cover, it has the re-enforcement spokes to handle the big power. This converter will safely handle 450 RWHP.

Here are some pictures of my new multi disk. It is a 3 disk clutch pack, 100 square inches for WOT Lock-Up capability. Billet front and piston of course. They will weigh 32.5lbs.
The shiny billet front, the splines grab the outside clutch teeth
This is the clutch pack installed in the front
The clutch pack separated
Clutch side of the apply piston, the castle teeth grab the inside clutches
The other side of the apply piston, reinforcement spokes for strength.
More pics if interested. LS1Tech Price $850
I will also be making a 4L80 version as well.

for all the doe we spend on our cars , $450 for a performance increase of atleast .2 - .3 seems like a bargain. i would guess theres no difference in normal driving the $400 3200 stall vs the $850 3600. im also curious if someone can explain why the billet converter is so much more efficient? thx
