I like as much stall as possible. I ran a very similar combination with a 3000 and it worked very well. :shock:

Dennis, did you have an auxillary trans fluid cooler with that converter (or any high stall converter really)? I know my truck barely turns 3000 rpm at 75 mph with 2.76 gearing (and small tires, works out to about a 3.00:1 effective rear ratio). Seems like that 'loose' of a converter would build a lot of heat on the street. Just curious. :?:

For comparison on my stock 64, I stomped on the brakes and floored it...........


The converter stalled at 1750 rpm.

Contrary to what many would like you to believe, a loose converter will not necessarily be slipping going down the road. I have had daily drivers with converters as loose as 3800 with no troubles. Yes, I aslways run an auxillary cooler. :shock:
