Compare the 335 to the 210+. Like for like the 335 is more expensive.
If you're sending the 210 unit back anyway, surely you can do that with either upgrade?
The 335 will undoubtedly push too much boost at lower RPM for a stock block. You'll either need to run massive overlap (if even that works) or you'll bend rods. We already know the rods on these are a potential week point when you go bumping up low end cylinder pressures.
