Thread: What rockers should I run?

Hello guys, I'm Neal Hanson and have been working on my natural aspired 3800. I have some questions for you. So far what have done is had the block bored to 20000 thoudnds over and put in JE Forged pistons (flat top) and rings. H-Beam connecting rods. Crank ground and hardened. X-P Hot cam. Removed the balance shaft and filled the gullys Put on double timing chain set. New oil pump with machined cover. New timing cover. I have ZZP heads stage 3 with the multi layer metal head gasket to put on. What kind of rockers should I use? LS7 lifters. L36 supercharger kit. would the 33# injectors be right for this set up? ZZP Headers with egr delete. What size down pipe should i use? No cat but what would be good to use for exhaust after the down pipe? Should i run an inner cooler? What kind of spark plugs should i run? The super charger has the 3.8 pully can i go smaller and how much? What are your thoughts on this build any concerns? Any tips or suggestions?
Thanks again.

Thanks again.

you are asking a lot of different questions here and need to learn some engine theory. a good place to start is by reading the safely modding your 3800.
