Locally there was a 70 or 71 Duster sitting outside of a body shop for years. It was orange with some goofy *** stripes down the side and a big hood scoop. It was a 340 with W2 heads and nitrous.
Car disappeared then years later came up for sale so, a couple buddies and I went to check it out...
So, my cousin is going through something similar right now. He has been getting shots in his eye once a week for a few weeks and he is almost back to normal. He told me the other day he thinks this next shot will put his vision back to what it was before. Hopefully this is the case for you also...
I have 2 Proform 67013 fans in a shroud with adjustable Proform controller. This set up runs off a probe that goes in the fins of the radiator but, I have a harness to allow them to run off a switch in the block also. I have all the paper work for the fans and controller. This fits a 26"...
Your all good!! Most everybody here are super cool and some great knowledge. I'm grandfathered in because besides my Challenger i also have an A body..lol
I'm really not sure what all was done to the heads. The intake has some porting done and the divider milled down about 1/2 ". Peak torque was 4700 rpm and peak horsepower at 5900. Carb is a Holley 850 DP.
The 512 in my 71 Challenger is not as built as your wanting to go and I can tell you, it keeps up with Hellcats as is. It has a 251 at .050 Lunati hydraulic roller cam. Mine has about the same compression as your talking about and an Edelbrock RPM intake. It also only has the 440 source stealth...
