I am running a 71 318 with stock crank and rods, new balancer for a 318. Build will be like the Hot Rod mag. "Junkyard Jewel" but with retro roller cam and aluminum heads.
My friend is running a 73 340, external balanced with original harmonic balancer and I believe a B & M flex plate. He said it has a neutral balanced converter so his flex plate must be externally balanced to his combo then (he didn't build it, just recently bought the car).
The reason I am asking is because we are both going to do the 8hp70 behind our small blocks and I making sure we have all the info we need. I thank you guys for supplying that info.
Some other stuff I need to know: stock 8hp70 flex plate and torque converter - are they neutral balanced or external balanced? Can I tell by looking at them? I have one on the way to me now, be a little while before I get it to look at the parts.
