My V10 performance top end "swap"

thanks for the info. We decided to not swap the cam. Doing a mild port and polish, gasket matching, valve lapping, new springs and lifters. Upgraded fuel injectors, headers, and throttle body upgrade.

Used Manley stainless valves. Gorgeous pieces, radius exhaust, machinist back cut intakes.
Be aware, Viper exhaust valves slightly smaller, new seats in order.
Installed spring height greater, decide if that matters to you.

Here it is, the long awaited Dyno test. A little disappointing on HP but torque was great. Now the test was not idea. We had no fan setup, it was really humid (had a severe T-storm an hour later), and these are just raw values no correction. There is a minimum 20% loss but probably closer to 30% with the 10ply 35s and auto. At 30% it made 330hp and 500ft lbs. It made over 450ft lbs at 2200rpm. This was on a conservative 87 tune.
