Edelbrock 60899 is the heads i have and use (64cc), KB pistons that i use (KB135) have a -18cc dish that will make 9.71 in compression (well in the recommended area from the cam manufactuer: Comp cams) The block is milled 1 hundreds of a millimeter as well.
A have reason to believe (after some snooping around) that the dyno i tested doesn´t work probably with automatic transmission without lockup or that the numbers can`t be accurate (says enginebuilders i have talked to)
I will check if the secondaries opens as they should.
All under 6.27 litres is a starter.

08-13-2007 #22I have changed the secondary spring so that they open earlier at lesser vacuum.
The differance was noticeable but just that.All under 6.27 litres is a starter.
08-13-2007 #23How was the HP at both flywheel & the rear wheel determined? I am shocked that you could lose only 27hp through the driveline.
