What is the max lift and duration cam that can be installed in a base 383 Roadrunner engine?

I have read 484 to be safe in an early stock engine if you float a 509 the valves will hit. Take into consideration the duration and have fat head gaskets been installed. The later smog engine will take more lift but don't have the compression to make a big stick work. Its real easy to over cam a motor.What is the max lift and duration cam that can be installed in a base 383 Roadrunner engine?

have to agree after having mine done from the ground up recently. Machining the block was probably the longest part of the process, wouldnt trust my block with just anyone, and anyone worth their weight in salt wont have much free time.A suggestion: Unless you have an “in” at your local machine shoppe, IMHO you would be $ ahead to do a crate motor.
Everybody should build one, but the money involved in machine work will eat you alive. I’ll bet it would be way(!) over your anticipated budget
An option I like is get an assembled short block. You can then pick your own cam, cylinder heads, valvetrain, and ancillary stuff.
I believeyou’d be money and time ahead.
I must be lucky to have a good reasonable shop near me, I enjoy building them.
Me too. Best part of any build. Been best buddies with my machinist since 1981. If you see me buy a crate motor you'll know that an "Invasion of the Body Snatchers" type of event has taken place.I enjoy building them.
