MY brother and I have been working on this car for the last six months. My brother bought it for $900, and it ran for two days. The care blew a head gasket, so we did what any respect full car enthusiast would do. We ordered a used Japanese motor from an independent motor company. We finally got it running about a month ago, and are now running in to some problems. The car gets terrible gas mileage and runs the worst when we time it. Any suggestions or Ideas.

P.S. I'm new to the site. I was refereed here by my friend who is building his 88' All-trac. Thanks for reading.
