while we are happy to have you here you should be on Toymods. There is a massive thread on toymods about the 18rg which is the twin cam version of your engine. Before posting make sure you do a search there, you will need to register first. Keep in mind they are often a nostalgic bunch and make emotional decisions about keeping old engines because it feels right or something. The 18R engines are old and finding people to do a good job tuning those carbs can be an issue. Me personally I would want something more reliable, smoother and more fuel efficient. In your car I think a 3sge beams engine would be a total win. Kaizen workshop on here sometimes gets them in, check out the sponsors section.
