Care for some numbers anyone?
560 hp, 630 ft/lbs torque :cool: , slapped the carbs and intake on from the old motor, threw in the old distributor and not much for tuning. In the last couple of months I swapped in ProMax metering blocks in and a Pertonix Ignitor under the cap so those things were well tested and swapped over without any issue.
Can't wait to do a big smokey burnout....
dstryr said:Just got back from my lunch break. Will put my 2" Doug's Headers on in place of the 1-7/8" fenderwell headers he used to break it in and do some initial tuning.
Jetted at 66s in the center and 84s in the outboards and my headers made 598hp and 652lbs/ft of torque :loco: , so we're done screwing with it. Don't know if I will get it into the car with the cooler weather, but you never know. :jester:
dstryr said:Here are the basics:
I bought the block and started working on a wish list in early 2006 and being the first engine I had ever had built I wanted to be sure it would be streetable on pump gas. After a few PMs with Cab Burge on Moparts I started down the road of building a solid lifter motor. Dwayne Porter supplied the Comp Cams and Harland-Sharp items and Ron(Firefighter3931) and a few others on dodgecharger.com provided a fair amount of insight as it was going together.
Ag & Industrial fired it for the first time last Tuesday before Thanksgiving, ran it for 20 minutes and changed oil. Will opened the filter and saw no issues so he changed the oil, let it cool overnight and ran it another 20 minutes on Wednesday. I stopped in after work that day and it was almost cooled off from the earlier run. He fired it for me and I was damn glad to hear it run. :banana:
We are having some issues in that the outboards are not coming open with the engine vacuum alone and the pulls he made were with a bolt through the slide on the center carb linkage to open the outboards manually. Vacuum is good, connections are tight so we will experiment with springs in the pods.
Center carb is jetted 66s and outboards are 84s.

I'll post a dyno printout as soon as I can get a copy. Hopefully we can tune a few more HP into it.
