cam/converter selection

good comprehensive info! much appreciated. the current eng was in a later dart & my racing buddy that does the driving (so far) wrecked it after several laps so I put that eng in the up & coming 63 dart. we tried to dyno it but it was too lean to do any WOT pulls & at that time I was not able to rejet it. the trans is a "regular" 904 running in third. I can call Howards & see if I can exchange/refund this unopened cam for one with 106 LSA & .050" more duration. yes I had read that the rear should be in the 5's & I have some 4.11's. I will call cope & see if I can exchange the converter (it's new) for a lower stall. & if not then send it in to someone to open it up when I find out where it needs to be at. CR limit is 9-1 static & I was very close to that. it is unported genuine EQ iron heads. I just bought a high dollar modified 2bbl & the venturis were the max allowed which was 1&3/8 iirc. dont have any info on the RPM coming out of the corner or RPM at the end of the straights but I have noted that & will find out and I will do a compression test.
