well im not real sure on the 66 i know the super b is something like an hx40 so its a bit smaller than a 66 i believe but if you can weld and fabricate then your good to go in fact some of my stuff was used from semis

if u dont mind, u got any pics of your setup? how does it run?

You need studs if you want to start packing more air in there.

well now i got more issues again. I CRACKED the head! #1 cylinder top exhuast ear is breaking off the head. i think the exhaust manifold is warping and shrinking and then breaking it off. im gonna try to get it welded to hold me over, then i am p-pumping a 24v and putting that in it.

I got shitty luck.

Run an .022 -.025" shoulder on your DV. Running a full or lazer cut with no shoulder will mess with duration and ruin your injection. Unless you are spinning really high RPM, you are really just hurting yourself. I wouldn't run them unless you were able to sit and spool it on the line, like sled pulling or racing. Also running higher timing like stated above will help tremendously, however the right supporting mods need to be done to allow it. I would run closer to 28-32 degrees with that set up. Maybe add a cam too.
