Built 273, what sure grip ratio with a A833 3.09 first gear

I agree ! I have a pair g78x14 26" tall, Snow tires I'm going to install this spring and see how they hook . heard rumors that snow tires hook fairly well on the street or track. They have been in my basement for 50 years and still look like new , nice and soft still. should be interesting. I just want to burn m up !
G's eh? I haven't seen those since about 71/72. They didn't hook on my 1970 340 Swinger340/4speed/3.55......... That car went 98@3310#, in the qtr which,is 245hp, IIRC.That was 1971.
