well there are other builders who can do what u want for much less..drag porting generally runs around 500 to 600 bucks. a 4mm crank will run about 500 bucks. where is the extra 1000-1100 bucks going? takin the motor out and puttin it back in?? even at a shop rate of 50 or 60 bucks an hour you are still paying entirely too much. taking a motor out takes about 30 mins TOPS... i know of one builder who charges 100 bucks to put a motor together. so i guess i dont see where you are putting 1000 bucks of ur money. if you go elsewhere i can guarantee you will get MUCH more for your money. whether it be ssr, packard, a&s, fast, passion, redline, and so on you will get a lot more for 2200 bucks...
and by the way, you can most def run t5s on cubs. sure you wont get the most potential out of the motor but its gonna run as good and in some cases better than most stock cylinder motors..
