[Propwash]

Thanks! I have a Lunati Bracketmaster in my Coronet and I like it....No issues. Good to hear they got such a Vet on the floor

I would definately consult the professionals (Comp Cams, Hughes, Cam Motion.....)on what it is you want out of the engine combination. My 440/512 is going to be a daily driver with the occassional 1320 venture. I called Comp Cams and they asked very specific questions about the vehicle and engine combination. I settled on a hydraulic roller with advertised duration of 281/287, @ .050 the duration is 230/236, and the lift with a 1.6 rocker will be 622/625. Other specs are 109 lobe centerline and 111 lobe separation. It comes down to what you want, like Burger King.

If you just gotta wuss out, here's what I would recommend.

Hay now, that is the cam I'm using in my 512 (ok its actually 505, only 0.030" over)
The 440 source kit with 17cc dished pistons, zero deck block, and 84cc head came out to 10.3:1 compression.
I am using 1.7:1 rocker arms, so valve lift is 0.617"/0.614", and I used the ISKY 8005A valve springs.
RPM intake and 770 cfm Holley. The intake/carb are only temporary till I can afford fuel injection.
The cam should make tuning the FI setup easier.
The small 1-7/8" TTI headers make fitment and changing spark plugs easier. I went with the TTI 2.5" "X" exhaust in case I want to goto a quieter muffler. I could not find any quiet 3" mufflers? The super turbo mufflers in the TTI kit sound good, but at 3,500+ RPM highway speed (4.10:1 rear gears) they get annoying. I will see if the 5-speed trans (Keisler 700SS) will help when I get it.
