Here are a couple pictures of that mustang. 66, 332 stroker motor, solid roller cam, victor jr intake, afr heads, 750 mighty demon carb, 5 speed trans, 9" rear with Detroit locker, Bought it when I was 14, spent every penny I could earn on it. Was able to get it on the road shortly after 16th birthday, and was my daily driver for about 2 years. Sits in the garage 300 days of the year now. Took it to the strip couple years ago, got a 12.7 with street tires. It will run mid to high 11's with some tuning and slicks. Currently fuel line from tank is too small and it runs out of fuel in 3rd and 5th gear, making tuning a bit difficult.
Here is also my old jeep I use to have. You can see there the 5.0 i had in it. Kinda rough looking, but I did that in my drive way while i was away at college.
So there you go, now you can kinda see why I want to go 4.6 or 5.4. I want to take my time, and enjoy a new challenge.
