OEM lift which is 390/410 for the 327's, any duration. Look at the blueprint spec's for 1968 and it will show all carbs, heads, intakes, ect. for those combos...some parts may be superseded and aftermarket allowed. Any transmission with a maximum of three forward speeds allowed, same manufacturer as car. Between the rulebook, blueprint guides and aftermarket approved products you should be able to get a good grasp of what is needed. Plenty of folks here will be glad to answer questions as they come up I'm sure.
