Cam for 418
Attention cam gurus. I have a 418 stroker that is being put togather. Undecided on heads. Have 823's and 243's currently leaning towards 823's cause I figure the cubes and a proper cam can make up for lack of low end from the 823's. Feel free to comment on that. 3.73 gears, would be racing @rpms between 1500-4500 most of the time but occasionally 3500-6800? So all in all needs to make power from 1500-6800, or some where in there. It will probably be a smaller cam. I know cam grinders/manufacturers have an "operating rpm" but they seem all over the place from similar grind-grind.
thanks for any reply

this particular car is 3100 w/o driver. Second gen camaro 3.73 gen. 6 speed. Car is 90%track 10%street. Dont really care about peak power. Tire height and gearing suggest the the rpms I listed and will be in for the speeds I will need for autox and road race. Glad you chimed in Summit. I was looking at a Summit truck cam 8719

The 8719 would certainly do the job, but our Stage 3 truck 222//231 112 + 5 .550/.550 would be an absolute bruiser. We close the intake valve at 38 degrees, so it's going to make a lot of power in the low and midrange. We rate it at 2200-6500 with a 5.7 and your cubes are going to use up that air earlier. The seat timing is pretty tight so it behaves like a 218 cam but makes more power everywhere.

Pay the fee that PAT.G charges ( roughly $50-$100) and get it custom. Pat G has stellar results with cam ing rect. port setups. Cam Motion can do a custom spec'd for free too. Either way, Cam Motion would be the cam supplier hands down.

All my options are open. Trying to understand how and why a cam operates in certain areas better than the next cam. I like to know how clocks work not just tell time. I understand duration lsa and advancement determine valve events. Which determines overlap. I take it PAT. G uses cam motion for grind?
