Re: Point/Counterpoint: DOHC v OHV
Wasn't there both a 396 BB and a 396 SB as well?

But in my opinion 396 is the same as 400 cubic inches especially since i qualified my statement with the word 'about' haha... The 402 BB was a 396 with a taller deck height for trucks as i seem to recall. The conversation wouldnt be complete if we didnt talk about the BBC canted valve angles and better rocker ratios, but like the LT5, weight and packaging were a big part of its demise. |

Re: Point/Counterpoint: DOHC v OHV
Isnt engine size and handgun caliber sayings similar? Your choice should start with a '4'.

Re: Point/Counterpoint: DOHC v OHV
It was meant to be a bit of a catchcan for the way other threads "evolve" or "devolve" depending on your point of view.

True big blocks are designed differently. They have a lot of cylinder material. The LS7 engine has almost paper thin cylinder walls. There is no service life in that engine.

The LS7's (part of the small block engine family Gen. III & IV) are modern day monsters that are clean from a emissions view and get decent fuel mileage . The cylinder walls are very easily replaced. The service life of an LS engine is an extremely long one.

Re: Point/Counterpoint: DOHC v OHV
Chevrolet BB's were produced until 2007 as Vortec L18 truck engines.
Mark IV which were the performance engines stopped production in Tonnawanda NY in 72.
