Yes, you would think the larger banshee motor would beat a ported BBK blaster but i seen the truth many times to me as well as others at the drag strip. Hate to say it but your leaving tons of power on the table by going unported. I dont know about reliability but i chose the 421 cheetah cub combo for the awsome kick in the pants power but i will say a set of stock flotek ported cylinders will run right with me, seen it done.
My 4mill cub is not ported but i chose going unported to keep some bottom end power and still have that awsome top end. 421 cub should put about 80HP on the table and thats more than enough for now, but i might choose to lose that bottom end power and go ported in the future.
There is stroked and ported BBK kits owned by members on here that will kill my 421 in 300 foot drag . Never underestimate a blaster motor.
Well damn....guess ill be getting ahold of ken next winter to port my banshee jugs.
So you think with the current setup ill be disappointed going from my blaster to the banshee?
