Little bit of a rant about Mopar heads...
I think in order to use the later block you have to run GT... don't you?
My understanding is that block is OK, but I do have to run a flat tappet camshaft.
I've dealt with this sort of thing before running NMRA and NMCA. Thing is I don't even know if the engine will be installed in a car in SE trim. The plan was to build it up without the crazy stupid parts (well, I'll have a real expensive 2 bbl carb), dyno it, and see if I think it has potential from there. If not, then I'll dump in the hydraulic roller cam, 4bbl intake, RHS heads, and turn it into an expensive bracket shortblock - LOL.
Yeah, getting the car down to class weight will be a challenge, much less a weight where I can have some ballast to move around. The index is low 13s.
Of course, I can't even get a set of heads, so I'm a long long way from worrying about any of that.
If anyone needs some good hydraulic roller 360 shortblocks, send them my way! hahahaha
