Well it's almost 2 years later and I finally have enough to start the Valiant:cheers::cheers:. I will be pulling the /six this weekend, i will be rebuilding from the block up, here's what i have planned for it, a holly 350 2barrel sitting on a cast 2 barrel intake, a comp cams 264s with 440 lift and 264 duration, electronic ignition from a 73 dart /six with a pertronix ignitor coil , oversize valve's 1.70" intake and 1.44" exhaust, and an electric fan. I would like to run a dual exhaust setup and a 10.0:1 CR . witch bring's me to my to a couple of question's is any one running headers on /six in 63, 64, or 65 valiant ? the next we have seen here a few thousand times before and no doubt will see again. Yes i have tried search function as well as tried asking at slant six.org but i still get so many conflicting responses my head feel's like exploding. Here's what i know so far minimum head volume is around 54cc and i need to remove roughly 0066" to reduce the volume by 1cc and i am told i can remove 090" any more and i need to shorten push rod's notch piston's so on, and then some say i can remove up to 110. my question is with a head gasket of .020" how much i shave to acheive a 10.0:1CR okay enough. as for the rest of the Valiant i am planning on leaving the stock a904 with fresh rebuild kit. inside bucket seat's and console from a coke bottle charger with floor shift interior color scheme red and white to match a red on white paint. with pic's as i go starting this weekend.
