I have this cam in my '68. It's got a TH400 and 3.55s, a Continental 13" stall, #16 heads and dished pistons. Runs about 3k at 70mph. I've often thought about putting a 700R4 in it. It's really docile around town, but it will wake up when you get on it. I still have to watch the timing on 91 octane, it will still ping a little if I get on it in the Summer unless I dial it back a few degrees or mix it with 100. Wasn't a problem with the Crower I had in it before, but I think this cam has more dynamic compression.

Cool and good to know.
My block has been bored 40 over and the seller provided me new pistons and rings that are ready for assembly except for the final cylinder hone. They are dished Keith Black 346.
I'm not familiar with these engines a lot so I don't know how #16 heads compare with the stock 350HP heads I have. The seller had those redone and ready for installing and figure with the dished pistons it would be about 9.0 to 1 compression.
91 octane is the best I can get where I live but it will be easy for me to control the timing as I'm planning on installing an Edelbrock Pro Flo 4 mpfi setup.
