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
letchcoreCJ7 jeepsr4ever wroteWhat heads are you using (casting #) and what application is the motor intended for? Head Casting # 3231475-1. The 401 will be used in my 79CJ7 for offroad use. Thanks,
ironman_gq 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:
jeepsr4ever K8600 works extremely well with the Edelbrock 600cfm carb and performer intake for a jeep.
