62 413 build

[midnightrider1818]

I have a 62 413 I want to put back together, going to run the original 324 heads but gonna clean up the bowls and ports just a little bit, planning on buying a set of pistons from hughes, just flat top pistons and probably running a .020 steel head gasket depending on compression ratio I calculate up, I have this cam out of my 440 I took out cause my 440 is a low compression late model engine and it was just to much for it, but now I'm thinking about running it in my 413, what you guys think, trying to build my engine around my cam

I completely understand working with what you have.
Others with more experience will chime in.
Myself , if i was going to buy pistons I would get a set for the low compression 440 and do the head work to it also
( prob 452s) ?
With that cam and a decent gear should be a good starting point.

Hughes offers 413 pistons? I checked and looks like all they have for RB's was for 440's. Silv-o-lite offers cast and I believe speed pro offers some flat-top hypereutectic ones, but there's lead times on those being made. Be prepared to do quite a bit of work to those old heads to get them to flow respectably with the small valves, but it's do-able. That cam is fairly rowdy for a street 413, even with a bit higher compressions than the 440, however you're going to need some deeper gears and a stall or manual to get most of the juice out of the combo your putting together. I hope others with more experience will chime in, but as @1967coronet indicated above, if you're already replacing pistons, then why not go with the 440 and the larger bore it already offers?

What gear and converter will you be running? Street driving or more track ? Do you want rumpity rump or friendly driver?

Will that came work? Sure. Will it be fun to drive ? Depends on how tolerant you are.

One size smaller would be a much better "street" cam IMO.

The XE284 likes 10.-1 compression with good flowing heads to shine.
