Nice job with the windshield. I did one with a friend about 50 years ago and they are not that easy to do. The 301 poly is a nice motor and makes pretty good power. Back in the sixties you could get a lot of speed parts for them. The 318 poly I had was the 2 four barrel version. I added an Isky cam and kit, Hedman headers and a Mallory dual point distributor. It was pretty quick. Your 57 is coming out nice and it is nice to see that it is not going to be turned into a 58 and be another "Christine" clone.
