408 Stroker

I want to thank everyone for all the great information. Car is a bone stock appearing '70 Swinger 340 with factory A/C. Book says it should weigh about 3100 lbs, add 200(Really!) for me.
I bet it weighs a good bit more. Weigh it if you can.
I'm leaning towards a set of 3.55's for my 741 8 3/4 with some type of SG.
IDK if your going to get all the lRs for a 741. I never really looked. Doctor Diff has brand new set ups that include everything & everything is new, case included.

Thanks to all for their sound advice.
Your welcome.

If the cam stays small.... a rpm w/a 1/2 spacer would be very good IMO.
Carb or FI is your call.
