Finally got the heads cc'ed and 3 ports came out to 58 1/3cc and the rest were 58cc. If 11.54:1 is too much than i'll go with a 0.049 gasket and that should put it at 11.25:1 which i know it can handle.

The cam will be either a

230/244 .544/.574 112 LSA

or

234/242 .548/.558 110 LSA

 

Could someone help me find the ABDC of these two cams so I can calculate my dynamic? Thanks.

 

Im at 11.4 with 93 octane. Ive been running some octane booster just incase but i havent heard any pinging.

 

whats the intake centerline and advertised durations on those cams? You can get IVC times from that. Is this on the stock shortblock?

 

I don't have a cam card for either =/. I just have the .50 duration and lift numbers. Stock block with .030 over and 3.750 crank.

 

the first cam is the cc306, you can find that info on comp's website

The other im not sure about.

 

Already looked, only has the .50 duration in their online catalog.

 

if only i didnt lose that cam card... :doh:

You should be fine with 11.54 with that cam. I ran 11:1 in texas heat with that cam.

Thar she blows...

Fire up that DCR calculator.

what is your quench height? what kinda pistons are you running (cc of the dish/flattop?)?

 

.039, -3.4cc

 

I got 8.52 :1 with the cc306 and my setup with 11.54:1 compression ratio. Now what about the other cam. I don't have desktop dyno here so can't find the ABDC of that second cam.

 

What calculator are you guys using? I went to two websites. One asks for cam timing abdc (which is 55) and the other asks for cam timing abdc +15 degrees (which is 70) anybody?

 

I got 8.46 DCR with the CC306 and cant seem to find any info on the other lobes. Either they are not Comp or Comp does not list them.

 

Somebody wanna do mine?
