I have a 408W all roller motor in my offroad truck, just ordered some new heads, the patriot performance SBF ones. It also has a Holley Commander 950 EFI TBI ( I know I shoulda got the MPI ) I'd like to ask and see if any of you guys are running this system witha motor like this and what are the tunes you are using. The motor is out of the truck now waiting for the heads so I cant go run it. This is what the motor goes in: http://www.4x4legend.com

Make sure you throughly check those heads when you get them, the quality has been showing to be quite lacking.

As far as your tune, it's an uncommon non-standard setup, so most likely you're gonna need some dyno time with a tuner. It's doubtful you'll find any type of canned tune for that setup that you can upload into the ECM and have it run properly. Without a custom tune you'll just be leaving a lot of power/mileage/performance on the table.

 

yeah it was doing that before. I'll check the heads well. Anyone know of a good dyno tuner in jacksonville florida?

 

thanks for the link on the patriot heads. very interesting. I'll call Gunnar monday and ask a few questions. I don't havethe money to go AFR's ( although I wish I did ) and I gotta get this thing running. I had World Windsor Sr heads on it but one got a nice crack in it. I'll probably end up with these anyways, I'll take some good pics and post em for you guys. I'm in no way an expert on motors but I'll try to analize them a bit post pics and let you guys finish up on them.

 

well, I found the money and I am going to do the AFR 185's the outlaw version. I'll get a set ordered thursday. Again thanks for theinformation.
