Yeah I did mean the twin cam head. The intake I currently have is just a single side draft Weber with an adapter mounted on a modified tracker intake manifold. After many hours of tinkering it produces almost as much power as the throttle body did

and only about 2mpg less.
Gotta get some automatic diffs to get the rpms down a bit at speed.
It is a lot of fun and it will go up my driveway.
