Fivepoint, back in 62 I had a 57 Chev 210 with a 283 hp 283 and 2.2 T10 with 5.38 .. We ran 105-106 but only 14 flat. This was before the Casler and M&H slicks. We just had Atlas Bucrons....street tires of the day. 6800 was about it due to stock valve springs.
Sure would like to have one of those FI today. We sold ours for $125 in 64. Dunb dumb.
