370's versus DD 1,2,3 Question

[DBR]

Question for those who have run both the 370 marine injectors and the DD1,2,or 3 injectors in their 12 valver. What were your experiences? I like the 370, but don't like the haze you get at low throttle input. I was curious if the DD injectors were cleaner at cruise and low throttle input. DBR

Hemi Dart has DD3's in his truck. It sounded like he was very happy with them. He went from 175's to 215's to the DD3's. IT sounded like he had a set of 370's, be sold them for the smoother running DD3's.



I'm sure he has better input.

I bought a set of dd3's & gov spring kit after getting dusted by a ratty old Furd p'up w/v8. He can't keep up now. The mileage is good the truck runs smooth. I would highly suggest getting the spring kit & crank it up otherwise you won't get the full benifit of the power,

I have run both the 370's and the dd3's.



The dd's make about 10 HP overall less than the 370's.

My dd3's added about 26HP over the 215's on the dyno with a number 11 plate and made no more smoke than the stock 215's did.

The 370's added about 9 more than the dd3's. The 370's smoke a little more than the dd3's in city driving because of the fuel sack in the 370's.



Fuel economy went up with the dd3's and the 370's went down just a bit.



370's are less expensive than the dd3's.



Personally I dont think you want to use a dd1 or a dd2. The increase would be little on the 2's and nill on the 1's.



I currently use the dd3's and have no complaints.
