If i had a 12a rex, with header, mid pipe, and flowmaster, then K&N, and a 50 shot of NOS, what times could I run in the 1/4??? What trap speed? Any one have a combo similar to this? Could the stock 12a take a 75 shot???? hehehhe, POWER!!!! Thanks for all the replies, Oh ya, please at least post your 12a 1/4 mile time and combo. No 13b's, i wanna see what the 12a's are all about.
