Do a little more research. I'd stay away from the SP2P and look for a LD4B intake. It's generally regarded to be the best intake period for 318's. They can be a little pricey. Here's one on eBay with a couple of days to go still.

I'd put a used 600 cfm Edelbrock on it with some dual exhaust and see how you like it? If you're trying to increase MPG you're going the wrong way. Once you put a four barrel on there, you won't be able to keep your foot out of it.

Edit: On your cold start video, always pump the gas at least once on a cold engine to set the choke and prime the engine with a shot of gas.

Thanks, mostly looking for highway mpg. I'll be adding cruise to it for sure. Good to know on the LD4B, I'll look into it. WIth the 2 bbl carb fixed and timing all dialed in now it's hard enough to keep my foot out of it. It just sounds so restricted with the current setup, she needs to breathe :)

I'm looking at financing this portion by selling my touring scooter, so I have time to look around for a deal.

I was hoping it would run from a no pedal cold situation. But of course you are right, it needs that pump to set the cold idle speed too.
