Do supercharged engines suffer equally from exhaust reversion like an NA engine with a larger overlapping camshaft? Does supercharging have a mitigating effect on reversion? I ask because i am currently working on a supercharged/intercooled combination for a 21ft Placecraft and i am considering running a crane roller camshaft that i have on the shelf. I intend to run lightning jacketed tubular headers with a long collector and water/exhaust mixing as far from the exhaust port as possible (with some consideration to the noise levels). The proposed camshaft has the following specs: 260/270 I/E duration, 110 lobe center, .663/.638 I/E lift. I ran this camshaft and solid roller lifters in a previous blown engine (mild setup) with success. If the proposed camshaft makes sense for my new project I would want to run hydraulic rollers this time.

Please let me know what you think.
Thanks in advance. CK
