i have a 67 chevelle that i'm building a 406 sb for. I plan on putting in the comp xe 284 cam. I currently have a TH350 with a b&m holeshot 2400 hundred stall. The catalog recommends a 2800 + stall. will i really see that much difference switching to a stall 400 rpm higher?. or should i save my money, what do u guys think?? thanks

With a cam that large, 240°/246° @ .050", I'd go to a 4000 stall converter and not mess around. I run a 3500 stall Vigilante in my 67 Nova, and it's really well matched to the 228° Erson Cam.

I'm running a similar cam in my 406.I purchased a 10" ATI treemaster...For all out racing you should go with the 4000 stall. For my street-strip application I had them tighten it up a little to a 3500? flash stall. Ive got a question mark next to the stall because I have'nt installed it yet. What gears,tire size,and transmission are you using?

you need to go with a 10" converter with that cam. what gears are you running? I run a comp XE274-h with a 11" 2400 stall and
3.73 gears. works great.

thanks for the info guys, i'm running the new trickflow 23 degree heads and about 10.5 compression. my rear gears are 3.55's. i wil be runnng BFG radials, this setup will be a weekend streetdriver, so streetability isnt really an issueit will see occasion strip use, but not much.

I personally wouldn't buy anything from TCI. I had one of those converters in my 81 El Camino, nice tourqe converter but I had so many problems with their transmissions I'll never buy anything else from them.

I also have heard of some negative comments about the TCI converters. ATI seems to have a good reputation with the racers I know.
I think this is one place that you truely get what you pay for.

Since you are going to run radials, keep the 2400 converter that you have. Traction will be a problem. If you go with a 3000 or especially 3500 your car will be slower cause you will never hook up. If you were running DOT's or slicks, I would say 3000 stall, but since you already have the 2400, you might as well try it and save some money. You can always change it later if your car dogs out of the hole, but it won't.

Just remember that when you have a lot of torque, it will push the stall speed higher.

I had the same setup as you, 406 / 350 trans /355 gears. I bought a 2600 stall convertor and with the torque of a 406 it push the stall to 2800 to 3000 rpm

Lonnie and I are on the same sheet of music, plus with a 3.55 rear gear you ABSOILUTELY do not want to run a 4000 stall. It will slip unless you cruise at 85mph. So going 55/65 will cause undue heat. Crazy. 3000 is tops for your app IMHO, but man, I run a stick, what the hell do I know.

I think you know a LOT, Gene!

I don't have experience with them, but I've read lots of good things about Coan converters (doesn't Ed use one of those?).
