I'm running a 402 w/ .5" roller cam in an '87. The HEI needs an advance curve and shim bac, so I'm diving in this evening. I'm planning on using the baseline advance kit from Mr. Gasket w/ 22degrees by 3000 RPM. The goal is 12 deg initial @750 rpm w/ 32 total (init + cent) by 3000 rpm. Feedback/recommendations? The existing curve is rediculous, it does not even start advancing until about 3K.
