My car has not been on the road since 2011. It will be soon! i rebuilt the engine last year and trying to trace a vacuum leak.. i suspect its the 24 year old stage 1 kit inlet manifold not being flat anymore.. anyhow the idle is up and down, slowly hunting.
-- on my hif44 if i put my finger on the vent tube it stalls immediately and if i spray brake cleaner down it the rpm rises. As its a 'vent' tube this should be venting to atmosphere only?
- also on the look out for a large bore inlet manifold to match the ports in the big valve head! is the maniflow one the only one available?
