Would like to get some more oomph from my 318

Well AJ, there are plenty of street cars with 4000 stall converters. Sure they might not be for everybody but they are streetable enough for many of us. I have two cars that I switch off for daily driving duty. One is a 73 RR, mild 400, old MP 175 converter that flashes to about 2800 and 2.76 gears. Other car is a 68 Satellite, 440, 292 .501 Comp cam , old Torker, 750 DP, 3.23 gears. This car has a 9.5 inch Dynamic converter built for the car with the knowledge that it was going to be street driven. This converter flashes to about 4500. This converter might feel a little loose to some but I'm used to it. It has been in the car since about 2003 , gets driven a lot, both in town and on the highway, and hasn't burned up the tranny yet. Of course a good cooler is a must. One thing your calculations don't take into account is that a looser converter helps shift recovery. I typically shift at 5800 and it drops back to about 4500. converter stall rpm and shift recovery rpm..... | Unlawfl's Race & Engine Tech | Moparts Forums
