The Isky 231-TA Turbo Cycle A cam will most likely give you the best mileage between all the camshaft choices you posted.
HP wise, it will be one of the lowest. I think that turbo camshaft has been around since the 70's. old school turbo type specs. Split duration though. Again, not a fan really.
Need to know exactly what HP goal you would want to grow into & not change the camshaft during the process., if I am reading you correctly?
I am not a fan of a split duration camshaft for a turbo app. So I would not recommend one.
Use a camshaft with a wide lobe center of 116 & wider for a better way to go IMO, it will give you the mileage you are looking for & still be able to make good power.
Camshaft specs for drag racing will be different than what you are looking for.
HP & TQ dyno numbers are just numbers & just bragging rights. Lets post some ET & MPH numbers. The 65 Elky makes how much HP/TQ & what MPH & ET with the Comp Cam you are currently using? 292, turbocharged ,intercooled, EFI, 3:55's, 62-1 Turbo, SPA turbo manifold, Clifford intake, straight pipe exhaust, no muffler, what else does it have?
I always wondered why he has a Offy intake on it? After all the engine dyno testing proving the Clifford intake the better choice, (putting myths to rest about the intakes) made the most HP etc, etc, yet, install a lesser performing intake manifold? Never ever recommending an Offy intake for any application, he only recommends a Clifford. Does not make sense.
All I have ever said , each intake has there design purposes. This intake design looks much better than a Clifford.
