Brian Hafliger OP master Joined: Jan 2003 Posts: 5,486 SoCal	I finally dyno tested this 505 cid (4.350x4.250) mopar with 440 source heads that I ported. 9.8:1 custom hyd. roller grind using new xfi lobe ported source heads MP dual plane intake 1000HP holley 1 7/8 headers Made 614TQ @3900rpm and 534HP @5200rpm. Idles nice at 850rpm. Here's a link to the porting post I started a few weeks ago and some pics.... https://board.moparts.org/ubbthreads/show...rue#Post4858551 4960265-dynographs001.jpg (450 downloads)

He has shumacher headers, so power will likely go down a bit over these. I think he plans on painting this thing like a stock engine so only tattle tale is the carb and intake but painted the intake won't be a quick give-a-way. I was really surprised at the TQ. And even the HP! I figured it might go 500HP but it went quite a bit over that. I just can't imagine how this DART is going to drive around with stock type tires Brian Hafliger

At the very top of this page, just above the first pic, there is a link to my post on porting those heads. I did not do a whole heck of alot of porting to them, rather just a mild street port job. No sand rolling, just re-did the valve job, slight chamber work, slight bowl work on intake and more on ex., and opened up the pushrod pinch on the intake side. That was it! Brian

Also going to put it on my website when I find time. I'm using the 3017 lobe for the intake, and 3317 for the exhaust. It's on a 113 lobe center too. Brian Hafliger

For example...if it were installed in a 1976 3/4 ton truck. That massive tq curve and small cam would allow you to keep your foot out of the throttle when towing up big grades.

Funny you should bring this up. Carl, my customer was joking about the "racing" carb I told him to run on this engine. He likes oem stuff so anyways...with some load on the engine at 2300rpm, fuel flow was pretty low. I would imagine your right, but it would depend on the rpm of the engine at your typical cruise speed as to just how much fuel the engine will consume. I can tell you with a smaller carb than this one, and tuned sharply, fuel mileage might not be so bad...but when you floor it....fogetaboutit
