Re: What? oh okay.....this is why you run a big block!
Ok i didnt realize you had good heads with work done to them. My motor is the passenger car motor and the heads are 292 so they are decent oval ports and they are shaved .030 for a little more compression. I think it should do decent but probably not as well as that 454. Plus it will be in the heavy chevelle compared to a truck that is lighter in the rear.
