Reversion on 502 with Quick and Quiet plus?
 

I'm putting together a 500 HP version 502 MPI.
Crane 168731 cam. Intake .587 Exhaust .610
Cam timing @.050 Intake duration 226 exhaust duration 236.
Card does not give LSA. I will be running CMI E tops with Corsa Quick & Quiet Plus diverters and GGB mufflers. The diverters look like they are jacketed and dump water right at the y-pipe connection.
Is this a safe combo or am I heading for trouble?

Your duration numbers are mild enough as long as you make sure your LSA on the cam is a minimum of 114, I would actually opt for a 116 Lsa and the motor will idle down farther and smoother with fuel injection and your Bravo will like you better to!

Good Luck with your project motor,

I believe the HP500efi uses a cam vary similar to the 731 with a 114°LSA.
The 731 has a 112°LSA...
