    368 heads

    I have a set of 368 heads that has just been redone and i bolted them up to a 76 500 .What problems will i run into by doing this . motor is not in car yet whaiting for headers to come in mail . I have found out that if you run 472 heads on a 500 you dont have to buy racing gas just add 1 can octane booster to every 5 gals of gas a buddy of mine runs his 500 this way with no problems at all.

    Re: 368 heads

    Find some 472/500 heads. Those 368 heads will not work. I offered some 120cc heads in a previous post but you did not reply. My trip to Ohio was posponed but I will be going to New Madison, OH as soon as this comming weekend if your interested. Email me if your interested. FYI, 368 parts are only good for a 368. Try to sell them if you can.
