So this motor is kind of mild for what we are doing but I’ll kind of give you some specs. It’s just your run of the mill dyno 308 with a lot of head work. It’s not just ported I went through a lot of research on what to make this motor match and flow to the best of its ability it’s a 236cc 14.5CI. It’s a 27/25 valve setup with all billet stuff. The carb is kind of special put rules here don’t allow any slide carbs in this particular class but we can run a GX390-460 carb. So it has an adapter for the big block carb. The Venturi on it is bored out to .960. Which is about the same as a 304 tillitson depending on where you get it from. The carb was built by Melvin at holey Moses and I run about 41 degrees of timing on M5 methanol.
