Stroker 340>416 Build Advice

a 416 with a decent head on it with a XE268H will make 450+. That's a DINKY camshaft and it will be out of steam rather low in the RPM range. Maybe 5500 at best. Seen a couple do just that. Was surprised by the results. I'd keep the compression in the mid 9 range or even 9.0 to run any pump swill available. The 4 inch arm will take care of the low end power.

Being a 4 speed you can run a bigger cam with the worry of in gear idle tuning issues that an auto may have.
