You may want to start your own thread. 2.5 BTDC ignition timing? Throw the book away if that's what you are using. Set it either by starter kickback or max vacuum.

For the OP, I wouldn't run anything bigger than the old 214/224 441-465 camshaft.

thanks,will give your suggestions a try and let you know how it goes. The 1970 motors manual said 2 1/2 ATDC.
