Breathing new life into the 318 in the Scamp!
Maybe I missed it, but is it just the stock 318 cam for now? If so, any plan on swapping it?
Watching......
Yeah, this is just a factory cam. It sounds to me like your engine has been a little more prepped than the one I'm working on.
If I do swap the camshaft for anything, I'll go with something that is ground for good torque to keep the snappy throttle response, but I don't have any plans right now to change anything from stock.
You'll se a little more exhaust flow with your setup. I have a pair of A body headers that are good, but I decided to keep the manifolds, because this car is actually a driver, even though it's kept nice.
If you do decide to run headers, you might consider wrapping them for better thermal insulation and scavenging. What kind of exhaust are you running?
The more I look at this carburetor, the more I like how it was engineered. It has all of the properties of a ThermoQuad without the hangups and from what I can tell and from what I have seen online, on Youtube and in other applications, mopar and other alike, is a reasonable gain over the Edelbrock 1405/1406 in HP and TQ, but I guess these things are supposed to be brilliant in throttle response. I want to find out!
Just know that before you buy one, if you decide to, that they are boxed up smelling like gas and are tuned wet for sea level with .080" jets in all four corners, if you need to get rods and jets for where you live.
I may set up an O2 sensor at the exhaust by the manifold to get AFR on the dot, but even if I decide to skip that, I'll be tuning for max vacuum and document any changes that I have had to make to the carb before leaving it.
I have already changed primary jets and metering rods on the factory step up springs. I may go with one stage leaner springs for this altitude and I'm thinking more about dropping secondary jets from .080" to at least a .076" if not an .074", but I haven't touched them yet.
I've pulled the valves on the heads and the guides and stems check out within tolerances. The exhaust valves have a little more pitting than I would like and are wide in the seats, so I'm also debating on having the heads tanked and do a 3 angle on the seats. We'll see what kind of price I can get on a cut set of valves and shims before. They will seal with lapping, I'm sure, but I'm really tempted at this point to do them while I have them off of the car.
