Better for towing? 396, 402, 427 (closed chamber) vs. 454 (open chamber)
Does anyone know if a 402bb or a 454bb is better for towing and pulling on a 1972 Chevy 3/4 ton 4x4? I think the 396, 402, & 427 had closed chamber heads for higher compression but the 454 had open chamber heads for lower compression. What are your opinions and/or experiences?
