I was going to put good parts in this, but back in 2000 I lost the motor in the wagon and everything I was going to spend on this went towards the wagon. Thus it is all stock, but fresh. Fully prepped, blueprinted and such, but stock with new rod bolts and the cam I had running stock adj rockers.. It likely has too much overlap for a blower, but, it works. I'd like to get a 445 kit for it and turn the wick up. Oh, someday, when I have the "extra" money=never.
I used to have an old race clutch in it, sintered iron. It was brutal to drive as it was really chattery. I finally wore it out and like I said, had the PP and used it with a new DF disc. A bit easier to drive, bit heavier pedal, but not as chattery.
It started with 600's off my pickup motor(428), then I found a pair of 660's. I went through them but still have not got them tuned perfect. Need to work out a bad mid range bog. That big alum box takes a lot of fuel to keep happy. I don't beat on it much, as I don't want to hurt it. It's a cruiser for the most part. Only took me 18 yrs to finally put a Unilite conversion in the stock distributor with an MSD. Starts easier, runs better now the points don't jump.
I've contemplated a twin turbo on my '69 F100. Kinda sneaky and would be a blast to drive. The black car is a PITA with that huge barn in your vision 24/7. I could make up a set of shorty headers turned upside down and mount the turbos over them and plumb them into each carb. Ya, sounds like a tuning nightmare
As for Wallace numbers? Hard to say how accurate. I only go by the MPH basically. I know the wagon made 550 hp back when and ran 116~ mph at mid 11's. Now it makes 625(dyno) and goes 123 mph(good day), 120(warm day) at 10.9.
