383 or 400 ?

A 400 with a .020 overbore is the same as a standard bore 440. If I had both a 383 AND a 400 I would put the 383 crank (forged) and rods in the 400 with forged lightweight magnum pistons from a .020" or .030" 440. TRW makes them. This yields 406" with a .020" over or 410-411" with a .030" over. It's much easier to install a low deck 383/400 in an a-body than a 440. Advantages abound. Later, Tom:cheers:

Excuse me? Lets clear this up once and for all. A standard 400 bore is 4.342". A standard 440 bore is 4.320". So, how in the hell can a .020 over 400 have the same bore as a standard 440 when it's already bigger to begin with? Some of yall really need math lessons. Bad. The 400 has the biggest bore of ALL the big blocks. Period.
