SB2s are a canted valve head, and the valve-train is heavy, and the castings were beefy. Ive heard 8 to 10 lbs per head, loaded, not sure on validity of that thou.

I talked to a pretty well known racer that didnt like them because it made the car handle different, that weight being up higher in the car, but really liked the way they ran.

The new stuff 10 or 11 degree wide bore stuff, you would think it would as heavy or heavier than SB2s, but i dont know. T Mac video / call with Chaz said the new stuff was like 370 lbs, which is wild, thats crazy light compared to the older days.

More weight off the front end is a good thing !

arent the Vic Hill ROX engines sb2?

arent the Vic Hill ROX engines sb2?

I really had no idea, but after reading a little about them it seems so. I guess the weight doesnt bother these modern SLMs or they just ported them enought and lightened them to solve that problem.

Engine Builder Mag, Vic Hill talks about the differences etc, good article.

My info was based on the old days LOL, i forget how long ive been around these Dirt cars.
