He was supposed to post pics, Yes the cruise control is very good, takes a little over one second to open the secondary after the primary is open full Bob Oldhead

If you changed any degrees how many RPM the maxium power RPM go up???? Oldhead

I was wondering if I added 6 more degrees or dropped 6 how much RPM would max. HP. would change? SBC-400 8 to 1 comp,300-235 heads,800 cfm carb,248-260 at .050 114 cl.,making 470 hp at 6250 rpm.Unblown of course...I WANT TO THANK THE GUYS THAT ANSWERED LAST TIME. OLDHEAD

oldhead

the only question i see that you asked is, will the rpm peak be higher with the smaller displacement engine given the same cam, and the answer is yes. based on your last post, i think youre looking for something else, but thats the answer for what was asked. You answered my question and I thank you...
