i am looking for someone that has or is, running the p600 set up. i have the intake, and the carbs done. gonna use holley 94's. extended throttle shafts, idle circuits plugged on inboard and outboard, WW II era carbs, model 21-29's w/ "ford" logo's. the power valve used are 6.5 not 5.5 as previously stated. was looking at a progressive linkage from vintage speed, or a cheeper one from offenhauser. vintages is all stainless w/ ball bushings, $135, offys is $69 but arms are aluminum, and cad plated steel rods, and not ball bushing type. my real question lies w/ drivability and reliability w/ this set up. most mopar guys i talk to think its a pipe dream, and a waste of money. my own dad had used this set up w/ a poly he put in a bullet nose studebaker, and said he never could get it dialed in w/ a progressive set up. and ended up having them all open together. so who has experience w/ them? has anyone dialed one in and driven one for an extended period of time?, does anyone know someone who has? i know i need to keep fuel pressure very low, since these things leak like sivs, but other than that, no one has any decent advice for me. i dont want to spend another dime until i'm more comfortable w/ what the final outcome is going to be. i'd like to get a cam soon, .450ish lift, but i need to know i have the induction it will need first. (i have spitfire headers too) this is my daily driver to and from work, store etc. would rather leave it stock than lose reliability. i was also thinking that maybe the power valves should be lower rating (4.5 to 5.5) also, but i'm not sure. and changing them on the car will be a mess, kinda want to have all my ducks in a row before i start, for less trouble shooting. but thats what the guy that built them thought i needed. sure he knows more than i do. anyways this e-mail has gotten way longer than i intended. sorry about that.
