This winter I plan on taking out the engine of my 1973 Opel GT. I also am going to have a Getrag 5-speed so I'll put that in at the same time. I'm going to bore my engine out then port and polish the exhaust manifold. While all of that is going on hopefully I'll also install a Weber 32/36 carb. I need help on finding a good cam to go with all of these accessories. I was looking at the Opel GT source Torquer with .407 lift and 256 duration with hydraulic lifters. Or would it be okay for me to use the Combination with .430 lift and 268 duration? Which one would be better?
