Yea, went catless with Kooks long tubes, Mini Bullet mid muffs and OE resos. Cam is a custom grind and 13:1 compression on pump gas. Built to be a daily driver and cruise machine believe it or not
Where do you find gasoline for that these days? Even with computer controlled ignition timing and fuel delivery that sounds like an engine that requires "race gas" to avoid being hobbled by retarded timing on pump gas.
By way of a comparison (yes I know you understand all this stuff but maybe not everyone reading will).....in a traditional set up like my old Corvette in the video just 10:1 compression requires premium pump gas and even at that the only reason I can get away with it safely is a long duration/high lift cam that limits the time in each compression stroke just enough to let an engine without the HIGH TECH knock sensors and computer controlled ignition timing to survive even this MODEST amount of "SQUEEZE".
Here in New Hampshire 93 Octane is what most Gas Stations carry so I'm a little safer than in a State where 91 is considered "Premium".........but we are a long way from the days of leaded gasoline and the over 100 octane fuel at the pump.
It's quite the testament to Modern Tech that 11:1 is pretty common today. Virtually nothing without a computer could make it's best power SAFELY on pump gas at 11:1.
10 years before my '79 Corvette was built there were lots factory delivered 11:1 motors in street cars, some higher than that......after the removal of lead and the subsequent drop in octane and tail pipe testing for emissions in the mid 1970s this Red Corvette in the video might still have been the RACIEST looking car of 1979 that you could buy.......and it's L82 350 was still a 4 bolt block..........BUT......you really got the "look" and no performance to back it up. It's weak HP figures and over-all dismal performance was in no small part due to it's flat as Montana cam profile, piss poor head design and the low compression ratio. I laugh today at the fact there are actually Corvette guys out there who'd prioritize the L82 option over the base model engine in these late 70s Corvettes. I figure that's CRAZY TALK......far better to focus on the condition of the car itself. The original engine should be considered a "throw away".
Given how VERY LOST Detroit's big 3 car makers were in this new era of "cleaner" tail pipe requirements........ if you'd ever told me that we'd eventually be able to buy base Camaros, Mustangs and Challengers with near 500HP and the premium power options in the 600-800HP range....... I'd have thought you were CRAZY!!
So this leads me to an obvious question.
You built your own 426 and that's pretty cool especially since Dodge has yet to see the wisdom and sales potential of offering up as "stock" option ........ any idea how much power you're making?
Is it "all motor" as I would hope for.......or have you done the super charging or turbo route? (still cool if you did but I just like the whole idea of a NA 426 in the image of the past)
