1/2 Rhoads???

I've been contemplating using a magnum 292 cam that I've had for sometime in a 383 build. My compression will be a little low for this cam at 9.45 and I was considering using a half set of Rhoads or Crane High Intensity lifters to help with cylinder pressure. Has anyone experimented with using just a half set on a single pattern cam?

I once used a set of rhoades lifters before, but my oil pressure was so high that they didn't bleed off at all and ended up lashing the rockers,

I assume you're thinking of using a set on the intake lobes only? There's no reason to worry about it- BUT with that being said Rhoads lifters are hard to predict and their action and noise is very application dependent- cam, springs, oil pressure, and oil are the main factors valve train weight can also play a role too though.

IMO I'f just get a more appropriate "white box" cam the cost is nearly the same and the results will be much better.

I have done this on a Pontiac 455, intake side. Worked fine. When I did the Pontiac, the cam and lifters were going to be replaced but that never happened because it ran fine as-is.

However, there's a lot to be said for choosing the correct cam from the get-go, and that would be my recommendation.
