Stepping up to a DPer?
750
You have rhs heads that flow great and a 360 in a dart.(a -body = light weight)
Sometimes a smaller carb helps, if you don't have the best combination of parts ,but in your case you have a great combo.
I run my 750 dp on my 318 because that"s what i had on the shelf and since it's in my cuda thats light weight, it works just fine.
If you know how to adjust a 750, it can almost run on anything with out any problems.In fact it run's great. :glasses8:
