Must be getting old so here is an update to what has happened to the old bus.
Got rid of the triple 45's / Wasn't happy with them as a road car and got sick of the carter pump groaning away and annoying crap out of me.
Went back to the Holly but couldn't stop it from fouling plugs.
Purchased a set of brand new 1 3/4 SU carbies, Scorcher ignition system, new leads and plugs. Fitted a o2 sensor port in headers for tuning. Car now goes beautiful after being tuned by a good mate who knows what he is doing.
Fitted new Koni yellow shocks and King standard springs/getting too old for low. LOL.
Now have a very enjoyable Z to drive.
Also have some fluted vent panels from Skillard.
