I had a 318 built by a local performance shop and was to be a 300 HP motor. Well to say the least it hasn't impressed me at this point in time. The shop hasn't impressed me with their support for what ever reason. I think this is because they are more chevy and ford people as they don't have the stuff to dyno a mopar but do for the others. It smokes like a ***** after app.400 total miles. Oil is coming from somewhere. I took it in and they looked at it and told me it was the PCV and to put a new one in and drive it......that will be $90. Ain't doin that no more. It has M/T holley cast valve covers on it and they mention that they may not be baffled correctly. I think Holley has an idea what they are doing so i don't think that holds much water. I'll give you a brief discription of the motor for now and i'll go out to the shop tomorrow and get the specs on the cam and give more details. But for now it is as follows:
72 318 block 30 over
holley 650 DP/DF
360 J heads with 2.02 valves
340 crank
edelbrock performer DP alum intake/now i have to cxhange the throttle cable because the intake is higher.
340 HP exhaust thru flowmasters to the rear stock resonators.
3.23 sure grip 8 3/4
It runs at 60 psi oil pressure
I was running it without a pcv with vented valve cover caps as the builde said he has done alot then i went to a pcv vented to the bottom of the back side of carb. I may get a MSD dist. this weekend in St Louis. It's running a stock dist right now but that don't have any thging to do wioth the oil smoking. I'll get back with more details tomorrow but if you guys have any suggestions before i drive this ***** off a cliff speak up. I'll have brick man post a pic of the car. I know it can be fixed. Just have to stand back and through more money at it.
