Sounds like a nice easy way to move up!

Sounds like a nice package.

Ray does the exchange go for 8.1 for trucks too? I'm thinking of switching out the one in my dually...8.1 w/ allison and 115K miles.

Yes, we have actually put together a few truck 8.1's around the country. It does take headers, exhaust and some serious ECM reprogram to get the best results, but 500HP plus with awesome low end torque and better milage actually results.

Ray,
What do you have for a 500EFI??

I would also be interested in something for my 500EFI.

Hey Ray,
Welcome to the OSO community and good luck with your new exchange program.

Thanks guys! Guess we got to get busy on a new intake manifold for the 500EFI's and 525EFI's, with all the great heads, cams and such already on the market, thats all these motors need to really get them cranked up to that 600HP level.
I will put it on our development list, seems to be a lot of interest!
