IMHO ... you need to decide ... street car or track car ...

I believe the 3800 stall can be a bit much in a street car ... a heavy street car at that. Powerglides work great at the track ... but at less than satisfactory in a high horsepower cruiser. They lack a low enough gear in first to work good without a lot of rear gear ratio ... and a lot of gear gear hurts cruising without a lot of high RPMS. Then you are adding a limiting factor of small tires ... to the equation.

I completely agree with Deuce.

A 3400 stall is fine if your car is going to spend 90% of its time at the track. Otherwise forget it. Also forget the powerglide. A built TH-350 or 400 would be MUCH better for the street.

Street car or race car, your choice.

66 chevelle trans and rear end

i,m in agreement with you on both counts,i have a 400 trans,with this,what rear ratio and convertor stall would be compatable for the odd quater run and more inclined for street use,thanks for the response,can you run some numbers on this one,i figured a max of 355 for the power-glide and 373 with a 400 transmission,we have a 20.00 friday night special at the local track,you can run all you want in the brackets,have a great day,paul
