I would REALLY like the TF 240, But the price after buying the extras would probably just be beyond what i am willing to spend..Now if they can use the stock shafts and rockers then maybe, but then there is the pushrod length issue i would need to figure out..Never dealt with that before and would have to figure out how to figure the length needed and all. The RPM's are probably the ones i end up with, just hope im happy with the improvement over what i got now.
