Thanks for the reply's guys. Yeah while it's down I'll throw some new engine mounts in, I was looking at these http://www.ebay.com.au/itm/261473255901 Putting a 12psi actuator in, is there a noticeable difference in getting the flapper mod done compared to stock? Also getting 3.5" dumpy, hi flo cat and injectors. Will I need valve springs?
