Motor is a 512 Stroker, 10.5:1 compression, Edelbrock Victor heads, dual eddy 1407's on a cross ram. Lunati solid flat tappet cam. .600/.600 lift, 276 @ .050. I recently installed a new MSD 6al box, new pro-billet distributor, and new Master Blaster coil. I was not happy with the timing curve I could put in the distributor. The motor wanted far to much initial timing to be happy, so total timing was too far advanced, and I could not tune. The motor was only happy at start and idle with 27* of initial. With the 10* bushing, I could get total timing at 37*, but was stuck there. Over the weekend, I locked out the distributor and installed a MSD start retard box (5* retard at start up). Now the car starts and idles perfectly and runs great at 33* locked out timing. However, it has developed a high rpm (over 4,000) misfire (feels like it is hitting a rev limiter). This did not exist before I locked out the distributor. Do I need to dial in a couple more degrees of timing?
