Looking back through old road tests in car magazines finds the high output Pontiac OHC 6 with a 4 speed runs zero to 60 in about 10 seconds. With the better tires today,it might run a half second faster.The HP was listed as 207 in most articles.The 67 Firebird probably weighs a little less than an AD truck ,so,better watch out for those kids in their 4 year old Neons,lol.
