Finishing my 401 need cam help

[letchcoreCJ7]

I am finally going to put in my 401 in the next week or so. The 360 started geting some blow by and now I have it down to the frame for paint so nows the time.

Here are my specs.

-AMC 401 bored .030 over to 4.195
-Crank turned .010
-Fel Pro Gassket thickness .050
-Deck cleareance .002
-Stock Cylinder heads 58cc
-Forged Speed Pro pistons L2380F Forged .030 over and 9.8-1 compression with my heads.
-Holly Truck Avenger 670 CFM offroad carb
-Edelbrock Performer intake
-Stock Rods
-Stock rockers

I dont have a cam, or new timming cover yet and that is the last piece of my build. I have an almost new Edelbrock Perfomer cam for the AMC's for idle to 4500rpm. But the ABDC is 42deg. It puts my DCR at near 8.8. I want to run on no higher then 91 octane.

Do I need to go to a higher ABDC to get my DCR lower? What is the max or near max Dynamic Compression ratio I can run on 91 or lower octane?

thanks,
Mike

What heads are you using (casting #) and what application is the motor intended for?

you need to find a cam that will work with your performer so I would look for a cam that works in the 1000-5000rpm range any bigger and your intake is going to be holding you back. Call up a good cam grinder like Engle racing and see what they recommend. tell them what you have and what you wanna do with it and they will help you pick a cam or even grind you a completely custom one if you want :lo1l:

K8600 works extremely well with the Edelbrock 600cfm carb and performer intake for a jeep.
