I'm having a very similar build done and have been waiting for almost a year for the build to be done. We are waiting for the transmission to be finished, but don't know when it will be completed due to supply issues. The transmission is a Tremec T-56 and only one part is holding it up.
Anyway, the engine is quite similar to the OP's build. Differences I see are minimal. Mine will be a 461 with a fully forged rotating assembly. Compression will be 9.9 to 1. Same type of heads as the OP's.
The cam seems to be up in the air at this point with my engine builder. I gave him the Butler RAIV roller cam I bought. I also have a cam with the same specs as previously suggested. It is a roller from Butler with the 236/242/112 specs. My engine builder thinks it is too radical for the build and would like me to go with the HR RAIV cam. I think the slightly bigger cam would be fine. Here are the cam cards. Also, going with Harland sharp roller rockers 1.65 with either cam.
I'm running two other 461's with 87CC Edelbrock aium. heads. The same builder went with the off the shelf Comp XR288HR cam. 236/242/110 and both are run with Doug's headers. Doesn't make any sense to me.
The 110 LSA is with the headers and the 112 LSA is for the RA manifolds.
