has anyone ever tried a 28p on a 271 fastech with 502 mag???? if so whats the top speed numbers

I ran a 28p Bravo one on my fastech 271 when it had the 502 mag. I could get 66 GPS out of it on a good day with light fuel. You could not spin it past 4800 rpm or so. The best thing would be to get a labbed 28 pitch. Jeff Wurl
