About the cam, if I had my druthers back, I'd go with a plit duration, with more on the exaust. What are the spec's of cam, call and askk for intake and exhaust lft, int and exh dur, and lobe seperation angles, valve overlap degrees. I'm curious
Yes it is best to match the torque converter.
You can call TCI, or Art Carr They will make one for you. Highly recommended.
Last I tried, B&M couldn't, but if they can it will probably save money.
Also, you might try Coan. I sold my stock one to a member on this site, "enyago"
They were going to disect it and build to his spec's
My Art Carr converter is great. Put it in D and go, no excess brake pressure holding at idle, shifts from park real smooth, and launches like a horse.
Keep us posted
