427 or 428 - How do I tell?

[joyridin']

Maybe you got a real good deal on the car, but if somebody told me it had a 427, and it had a 428, I'd be pretty upset. I would think a 427 car regardless of the brand would bring a pretty good buck...just for bragging rights if nothing else.

Oh wwell...I guess it is one of those "let the buyer beware" type of situations.

Not a lawyer but would think is seller tells you motor is a 427 and turns out to be a 428 or worse, I believe that you have a good case for a law suit. The buyer should know what he is buying , BUT also the seller better be careful of BS. It's too bad that in today's world TRUST and TRUTH has gone out the window with some people and would screw you for a nickle. I believe that Barrett/Jacksons has gone through this all ready for selling cars that are not what they claimed to be. Insurance is to protect them. Rick L.

Rawkkawler Mike If you are unhappy with the way the motor runs, some things need machine work to get them upto flow to match other parts. You said your intakes are not working. If they are stock out of the box, they will cost you about 10-20 hp in power and about 10-30 FT of torque. The 8 intake ports don't flow the same numbers and need to be cleaned up and to match the intake ports of the heads. How much work was done on the heads?? Full port job?? short radius of the valve short side? gasket match the intake and exhaust ports? The BIG killer is your exhaust system, running side pipes?? If yes, some systems cost from 10-40 HP and about the same in torque. The numbers you gave, are there from a chassic dyno or motor dyno? My numbers are off an motor dyno and you loss about 20% to drivetrain drain. This could be higher or lower depending on what tires you are running and wear numbers, Low wear numbers( soft tire compound) more drag. I can give you a guys number for fixiing the intake manifold. Cleaning up and porting it to have all ports within 3-4 cfm of each other and fixing the flow into each port for a better balance. This will also stop the lean cylinders. Mike there is alot more, send a P-M if you want to talk about this. Rick L.
