Yet again more W2 360 talk

There is NO flat tappet cam that will outperform a modern, aggressive, high lift roller cam. But there are consequences such as more stress on the valve train & since roller cam valvetrains have more component parts, more chance of failures....
A FT cam ground for Mopar's larger 904 lifter size allows for a more aggressive profile & narrows the gap between it & a roller cam. Cheaper too. Depends on budget & ultimate goal.
