Hello guys. Just bought a "71 SS with a '68 396 in it. I don't know much aabout big blocks - I was never lucky enough to have one in my younger days. Got a few questions. I don't have the car in my possession yet - have to go get it with a trailer this weekend - so I can't go look at the engine numbers yet.....BUT - when I drove it, it tachs about 3000 rpms at 55 mph. TH 400 tranny and a 4.11 rear. Does this sound right? If so - what is the approximate redline of a warmed-up 396?? The cam card says it is a .625 lift. How radical is this in a big block? Would a '68 396 have solid or hydraulic lifters? Where would I find specs for a '68 396 so that I can find out how much oil it takes, what plugs, misc parts, oil filter, etc.? I get a new 3.42 rear gear with the car. Anyone know if I switched to that what the rpms would be at say 65mph? What about going to a 700R4 tranny? Any help is appreciated. I am experienced in forum use (over 500 posts on a Dodge forum I belong to with my truck) - It's just been a long time since I had a muscle car. I hope to learn about it from you guys - and be around the forums to help out others after I learn. Thanks for any help!
