Did some more work on the LQ9 today. finished the cam swap finally. Borrowed a puller and pulled the stock single timing chain. Came off real nice with the puller. I installed the new JP billet double roller in its place. Next put on the Melling 10295 hp oil pump. You Must use the supplied spacers with the JP timing chain to move the pump out for clearance. I also had to clearance the inside of the front cover to clear the pump. Installed the front cover with a new front seal and gasket. Best way to align the cover is to leave the bolts finger tight until the balancer and oil pan are install. I had no problem getting the final 140 deg with just a breaker bar when torquing the balancer on. now time to pull the heads for new LS9 head gaskets and a set of 243 or 799 heads... still looking for them I have a comp camps trunion upgrade and a set of double springs from Brian Tooley racing on order as well. It getting close to ready to put back in the car.
