Cam For NA 945 - A or B?

Wanting to swap a cam into my NA 94 945 auto.

I put an IPD VX in another automatic 945 I have and it seems OK. Can feel a difference, but not the same as running a manual tranny (where you can control the rpm more).

Thinking of an "A" cam or "B" cam for the other 945.

Anybody run either the "A" or "B" in a 940 automatic? Impressions?

Thanks for any input.
 
Get the A since you'll need it to have a slot, unless you're running the block mount distributer or coil packs. They're really so close that I doubt you'll know the difference other than on a dyno.
 
The B cam is just a bit better than the A cam on almost every area. I'd just go with the B cam if you can get one for a good price, and if your engine accepts it.
 
Thanks for all the responses.

Interesting about a "T" cam in an auto NA... I was mainly wondering about cam choice with the auto tranny, and trying to get good power/torque inside the auto RPM range.

Reed, how is climbing hills with the "A" cam?

I have come to like the auto tranny in ways, but what I find frustrating is going up hills and not really being able to match rpms and gear to get a good "pull". Uphill the auto tranny always seems to be in either too low or too high a gear. ??? With a strong motor (V15 or VX cam) and 5-speed I could climb hills much better.

And yes, you can go quick in Brooklyn. Maybe not 100mph easily. I've gone pretty quick more than once on the BQE. But I mostly use my brick to go on road trips out of NYC.
 
I do t cam advance 4* with cam gear on an autotragic. It's the only way to get smilepower from buttdyno.

I also like to pull treestumps on the 3.73 rear
 
With my A cam I have the ipd adjustable gear at 2.5 degs advanced. I’m running 208cc yellow injectors out of a 960. On 89 octane I’m making 90whp and 100wtq with afr 14.7 all the way across the rpm. I’m working on trying to richen my afr to 12.5-12.8. I’m also running the eBay 2.5 turbo exhaust welded to my stock na downpipe. 4.10 rear and Pegasus 17” wheels
 
If you send me a picture of the Regina control unit I may be able to tell you if it has had the factory software upgrade. If not it makes a huge difference in drivability. I can do the upgrade for you also.

I wish I'd known about your shop last year, I came down and camped at hickory knob state park for the eclipse. I would stopped by to shoot the breeze.
 
Put the t cam in a 245 wagon, na, auto. Would maintain 110km/hr up most hills with 4 passengers, I was impressed. That's it tho, not much point in revving it out or trying to go much faster...it got a m46 and a k cam shortly after.
