So we where scrounging around pick and pull seeing what we could see. Lots of carburated SBC's to choose from, so I will be able to hopefully find one that will work. This weekend it is 75 bucks (you read it right) for a COMPLETE engine, from the air filter to the exhaust manifold!!!! So Looking around dad spotted what looked like a good 400 SBC (he said something about rare...) It was from a Impala, 70 or so. (anyone have any way of identifying it? engine code numbers? I couldnt find anything online..)
Anyways, my question was one of dads comments. He said that the 400's had a harmonic balancer. Would there be any reason why that harmonic balancer would make it NOT work? Oh While where in pick and pull, we'll be picking and pulling certain things from other engine's so that we have one "complete" engine. My dad said something about high performance ignition and dizzy... What cars would have that factory? What else should I "Swap"? Come on v8 guys I know your out there!! Andrew |

The 400 SBC will work. It is the same size as any other SBC. You must have the crank damper and flywheel from the unit, as Scott said, it is externally balanced.
For identification look for two things: 1.) The harmonic balancer will not be a round smooth circle. It will have a relief cut in it on the circumference about 1/3 of the way around. 2. The crank flange (where the flywheel/flexplate mounts will have a locating pin in it - the other do not and the flexplate has weights welded to it. A 400 SBC bored 0.030" with early "double humper heads - small valve (63 cc combustion chambers), flat top pistons and an ISKY 270 hydraulic cam will produce an honest 350 - 400 hp and TONS of torque. To mate the heads, you place a gasket on them and drill the steam relief holes in the head. You need a good cooling system. I know, I built this combination for my 16' jet boat and was able to blow off big blocks with a single 600 cfm double pumper mounted on a replica Z28 manifold. Stock they had 265 HP with a single 4 bbl. |
