Thanks guys for the information. I'll check these out. I'm planning to reproduce in 1/25 scale my 1976 Ford short w.b. E150 van. It had a 300-6, three speed manual trans. I used it as a personal vehicel, shop truck for my business and towed a drag race car around for years. Greta truck, the 300 was a great engine. Good torques, decent on gas and easy to work on in that chassis. I appreciate the help. Ron
