I found a 65MM on here for 100.00 shipped i have a gt40 intake lower and upper should i get or just hold off and get a 70mm t/b
If your talking about my bbk 65mm for sale buy my buy my!! lol
Cant beat the deal instead of spending $200-$300 on a new 1 + shipping buy my just took it off only has 4k miles on it $100 shipped

perfect size for your setup to btw, I only went to a bigger 1 due to my bult 306 h/c/i along with aftemarekt trickflow intake thats also ported with a 75mm opening so I stepped up to a larger 75mm, so 65mm would be perfect for yours being I think stock on are cars is a 56-60mm on gt's and cobras.
