On the 195 eliminators, based on chamber design and thermal properties, what is a target DCR you like to attempt to achieve? And, do you normally use the IVC at .050" + 15 method to calc DCR, or do you go by the advertised IVC (at .006" or whatever the cam mfg sets it at) ? Cam I'm looking at has 44 on the IVC at .050", so add 15 that gives 59 - using the KB calculator static is 10.16 and dynamic is 8.5, using advertised IVC of 63 and we get a dynamic of 8.2. Both of which seem kinda lame for an alum head combo. Camquest seems to think the combo will be 530 or so hp, and the same torque (afr heads, 412, solid roller 236/242 that you and I discussed). Some of the guys seem to be running DCR's in the low 9s with the AFR 195s.. What do you think, tony? Keep in mind, this is going to be running 93 octane. I have absolutely ZERO desire to mix additives and become a chemist. Also, my pistons are down .010" in the hole. I had assumed I could get a .030-.035" head gasket in a 4.200" bore, which as a poor assumption. I didn't realize all the thin gaskets are only 4.166" and smaller bore, so I might be screwed on quench..  See attached. -- Joe |
