I don't understand the complete mechanics of what the stall rpm does but I suspect it's a true 1:1 spin ratio, at a higher rpm.
your current C4 and converter will handle aything you throw at it. it won't hurt it. the only things you need to worry about is the proper vacuum signal and the converter we can help you find the right one. that is why it's suggested to stick with a 112 lobe center to keep as much vacuum as possible for ur stock C4.
I think your C4 will be perfectly capable of handling ANY naturally inspired mods you throw at it. and IMO I believe the stock converter to be fine withur choice of (264/274 112* .450)* cam.
*might be a little lumpy but should idle decently 650-800 rpm
Thank you MPG. The reason I was considering the 110 LC was because of the idle. I wanted a slight lope.
Why you ask??
I’m sitting at the stoplight; my engine has a smooth normal idle. A v8 Corvette stops along side and notices a neat FB Mustang. He thinks hummm cool and drives on..
I’m sitting at the stoplight; my engine has a lope at idle. A v8 Corvette stops along side and notices a cool FB Mustang with the sound of muscle. He thinks hummmm, wonder what’s under the hood. Let me find out when the light turns green. The light turns green, he burns rubber and I just calmly drive off.
I pass him 3 blocks down the road parked getting a speeding ticket….
All kidding aside, that was the only reason. I have no vacuum assist accessories other than timing. Not knowing what causes idle lope I just assumed it would be the LC’s.
Now I believe the cam picture is a lot clearer to me.
As I understand now the 264/264-112* will have smooth idle and max vacuum.
The 264/274 112* .450 will have a slight lope and still have good vacuum.
That is all I wanted… every thing else is eye candy..
Now that I have unrestricted access I’m thinking for $360
it might be a good idea to replace the converter with one that has a stall at 3300 rpm.
