Well, I thought I had made enough of a sacrifice to the convertible when I bought the new steering wheel, but I was wrong. Took her out for a cruise and when I got off the freeway I could hear a tick and a miss. Checked it out and I have a couple valves that aren't being moved by the cam very much anymore. I ad made the choice to reuse the Comp XE268H that came form the dead 451 and before that the 383 the car came with. Well now, that was a dumbass move on my part, even with the new lifters that were put in this 440. So, the Mopar guru helping me with this advised me to go with a roller cam this time. Checked out the various cams, and decided I wasn't going with Comp this time around. The Whiplash and the Voodoo cams have a good reputation and I talked with the folks and Lunati and settled on a Voodoo.

Should have it this week. Already got matching Lunati springs and roller lifters. Bought a set of Isky ductile iron rockers and sent them to Rocker Arms Unlimited to be bushed and refurbished. They will come back with new chromed rockers shafts, new hold downs and spacers and shims to eliminate the spring spacers they came with. Still trying to figure out the front cover/cam button drama that roller cams require but I'm getting there. I'm hoping this cam will wake up the 440 a bit more.
 
Search for my user name, i have made several reply posts to similar questions. I would recommend johnson lifters, i had problems with comp and morrel roller lifters. I currently have a custom straub cam, he ground using my cylinder flow data.

oops, I did not know that was a thing. I just deleted a few items in that in-box. My setup is as follows.

440 source 505/512 stroker kit ~ 10.25.1 ish to 10.5:1 ish compression.

440 source CNC stealth heads with thier rockers and shafts, smith brothers custom pushrods.

Custom Straub cam
Intake Exhaust
@.050 234 244
Lift .573 .563

Originally had a comp roller
xr280hr

4767 lbs

Quick fuel SS 830, Edelbrock performer RPM, full TTI exhaust

I had a .083 wall drive shaft with 1350 sized u-joints built at my local drivetrain shop, stock axle 3:23 ratio with detroit locker

Transgo TF2 shift kit and 2800 stall made by A1 converters. I believe its an 11" it is un-noticible in street driving. I only use the trans cooler built in the radiator (it is a true 4 core radiator) no fan shroud, stock fan that came without a fan clutch.

It has cal-tracs traction bars on stock springs

Thanks @MEV, what did you end up going with as far as ignition setup? Pertronix Ignitor? HEI dizzy?
 
I have ran the stock distributor with a pertronix HEI conversion
I have run a 4-seconds flat stock style distributor and control box.
Currently i have a billet distributor from them with their control box.

I'm running an FBO ignition myself.
