Inline 6 vs V6
I would think an inline engine of the same size as a V would be more expensive and heavier? I'm thinking of the 4.0 DOHC straight 6 in our Jags, versus something like the 4.0 V8 in the X308? For example, how stout the engine block, crank, and other parts in an inline engine would have to be stronger than a similar size in a V configuration, due to it's bigger size? Doesn't a 350 Chevy small block weigh considerably less than the 4.0 Jag straight 6, and that's a 5.7 liter versus the 4.0?
Most Chevrolet/GM V8 engines are of a pushrod design and made from cast iron so they weigh more. The newer GM engines, although still using the archaic pushrod layout, are made from aluminium and are thus lighter than the earlier cast iron versions. Most pushrod design engines produce good torque, but do not have a broad rpm range due to all the moving valve train components.
My old 76 Firebird had an I6, 250 CI, and it looked like heavy lump. Why a 6 cylinder in a Firebird, I'll never understand. At that time, you could get up to a 440 CI...LOL
