351 windsor BUDGET build up
The build you describe will be very expensive. Better to do a good stock+ rebuild on the 351W and add some good heads and an intake with either a flat tappet or roller in the 230/240 intake range. You can get 351W H beams for about $500 if you like insurance.
Expensive items in your original idea include: offset grinding crank - big $$$ and balancing may be more expensive than normal, modifying Chevy rods to fit a Ford journal (chev is wider), modifying 351C-2V heads for W water flow and finding a Clevlor intake - $350~$500.
The new generation heads (like AFR) run rings around the 2V's. Mine are heavily ported and flow just a bit more than some of the Edelbrock RPM heads for a SBF.
If you want a stroker, just buy one of the kits from Flatlander, Speed-O-Motive, Scat, etc. Cheaper in the long run than spalling together questionable modified stock parts.
