Not sure if it would run on 87 with Edelbrock 63cc heads and Felpro 1008's, Voodoo 60403 226 int./234 exh.





I have a 416 stroker with Edelbrock heads “63 cc” that we cc’d at 65 +/-1 cc. And 21cc Icon dish pistons with quench pad. Measured at 9.7:1 compression. It less than .035 quench. And has all chamber edges or potential hot spots deburred including chamber matched to bore. I have the older Comp 274-S cam with 236/241 @050 and .502/511”

I can’t run 87 octane. Maybe if I dialed timing way back.







Not questioning what you say, but it seems something might be off. Less than 10 to 1 with aluminum heads should be no problem with the cam you mentioned. What timing are you running? What is your AFR? Have you tried a colder plug? Also is your block an LA or Magnum?
