What about in the Comp Cam range,being overseas freight is a killer,i have to buy most of my parts from Classics it just makes it easier as i am buying other parts to combine . Not sure if i will replace the rear gears,are they good for cruizing? Std converter,not sure of compression ratio,i bought the engine separately from the car,the heads are off so i can check size of valves,bores etc... Whats the std size of the bores? Thanx Chris
