Re: 77 c10 5.3ls turbo

I had not anticipated changing out the cam but after much debate I decided to. Ordered a trickflow cam tps30602001. .560 lift/216/220 duration with 114lsa with matching valve springs. The guy that will be tuning the car indicated that 80lbs injectors might be a bit big for the stock cam. Since i have a feeling this boost deal is going to be addictive i figure i might as well start off with a cam that can support 80lbs injectors. Dont want to have to do 60lbs now and then 80lbs in 12 months.

I have the wastegate, blow off valve, oil lines and a few other thing ready to go after I get the cam and springs installed. Also need to drop off hot side manifold and intercooler pupe to get some welding done.
