408 Magnum Stroker Build...cam selection

Hi everyone,

These place has always been a superb wealth of information. I thought I would also ask you guys for advice again. I'd like to confirm one last thing: Cam + converter. I am hoping to reuse my factory 1970 "high stall" converter from my 340. The specs in the FSM shows that it has a stall speed of 2250-2450 behind the 340 motor. The same converter (apparently) will have a stall speed of 2350-2650 put behind a 383.

I've recently *mostly* decided on the Comp XE274 roller rocker cam. My builder was questioning if the XE280 would work, but some of the advice I've been getting from some is that the XE274 should be seen as the biggest. Specs:

Magnum 360 -> 408, internally balanced, forged pistons, cast crank
EQ Ported heads with 1.94/1.6 valves. 1.6 ratio rockers
LD340 intake
Carter 440 AVS carb
Factory 340 Hipo manifolds (ceramic coated in OE grey)
TTI 2.5" exhaust w/ super turbos
3.73 Eaton rear end
Factory air cleaner

The goal obviously is to create an identical looking 340 (minus the LD340 and the EQ heads) while the original 340 gets refurbished and safely stored.

So with this combo, what do you guys think about the XE274 w/ factory Hi Performance converter in a 3500lb e-body? Hot street is really what I'm going for. It may see the track once in awhile, but just a good street driver is what I'm aiming for.
