Good Morning, I'm switching to a 700R4 trans next spring and I'm not sure which intake and carb to use. I have a 57 two door belAir with a (1962) 283 and a powerglide which really runs well. I've put 11,000 miles on the car in the last 2 years with long trips to the mid west and Canada, I live in Md.. The hard shifting and low MPG are getting on my nerves. I was thinking of going to a small 380 Holley.
