What I am asking here, is how well a 2350-2650 converter (behind a 383) or 2250 - 2450 converter (behind a 340) would fare behind a XR274 cam for a street driven stroker vehicle wanting to hit in the 13s with the specs above.
You obviously aren't looking for performance. So stick with manifolds, stock converter and the xr274... It will probably still run better than 13's at sea level. But with the heads, cam and combo that engine is being choked to death.
