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.
