I have a 72 goon and have built a motor for it a couple years ago but I'm anxious to build another one. I currently have an l20b bored 1mm over,280zx flat tops pistons, port and polished offenhauser intake manifold and port and polished u67 head, mild rv 2 cam, matchbox dizzy, crank scraper, 280zx turbo oil pump(better flow) aluminum 3 core radiator....fully adjustable coil overs all around and 4 linked. Like I said I want to build another motor with good power! I don't mind mixing race gas. I have a couple ideas so far but just looking for any suggestions. Thanks guys
