Probably a Dumb 318 Question
Uh oh will the 112lsa cam profile not be roudy at all will it be embarrassing :)
A stock LSA is 114, at 112, it’ll still sound smooth, but not stock. Don’t worry about it, run it and have fun.
110 is the typical cam that has a chop sound to the idle.
The .500 lift is not Taking advantage of the cylinder heads air flow capabilities. You could port the 318 head, save money, out flow the SM heads and make more power.
The duration is fine. You’ll make power up to approximately 5500.
If you strip test it. Shift there and run again. Shift 300 rpm later. Check et & speeds. Try again and shift at 6K. Check et and speeds. Rinse and repeat at different rpm’s.
It’ll be a fun engine. Worry not.
Go to YouTube and search Charlie Servidio where he ports cylinder heads. He has done 318 heads and will show flow test results.
