Thanks for the reply! Yes the Ottawa valley area is basically at sea level, actually our average barometer is pretty high most of the time! The heads are the 302 closed chamber style and stock valves, I milled them .015 and the chambers came in at exactly 60cc. I haven't decked the block yet but my intention was to peel off .020, currently the pistons are down .056 in the hole, I found a .002 dip in between a bore on the deck that has me concerned hence the reason to mill the deck. We bought Mr gasket 1121 head gaskets that compress to .028 or an advertised 6.177cc volume. If I left it all alone (not milling the block deck .020) the Speedmaster comp calculator shows 9.43:1, also my quench space would be .084. Decking the block .020 brings the comp upto 9.89 but will bring the quench to .064. I picked the cam based on the quick rate and being exhaust biased but I figured the cylinder pressures would start to approach street fuel limits. Perhaps I should leave the block deck alone and be happy with the lower 9.43 comp ratio. I thought that having the cam centerlining at a tick over 110 as opposed to the recommended 108 ICL would help bleed off some lower end pressure but the folks at Lunati recommend bringing it to 108 period. Many years ago ( I've been out of the loop for a while raising a family and all of that!) I had run the old Ultradyne "tight lash" mechanical flat tappet cam in the past on a B block stroker combo and it just worked great. These voodoo cams (although hydraulic) remind me of really taking advantage of the larger lifter. We bought the Lunati cam complete kit, however, it comes with the three keyway crank sprocket and the advance keyway is too much. Might have to break the budget and get the 9 keyway setup. Or I can machine up an offset woodruff key for the cam if I can figure out the offset for 2 degrees.
