75sv1 Posted January 18 Share Posted January 18 I purchase a NOS Chevy LS 5.3 block off of E-Bay. It arrived yesterday. I am looking for ideas on components. I am thinking of a stock plus. Also, to upgrade the rods. Look for Hyper Eutectic pistons. This will be a built rig, XJ. I do want some sort of fuel mileage. I'd say my present plan: Scat 9000 crank if available (cast), Scat or Eagle I beam rods. I might go for H beam rods. 6.093, 6.100 or 6.125? Also, that affects the piston selection. I do see some Forged pistons from Hyper Eutectic alloy. ??? Rings molly of some brand. I did use Hastings on my two strokers. I'm looking to replace the stock cam bearings with Durabonds. King coated mains and rod bearings. I want a camshaft in the 800-5,800 RPM range. So, far its Compcam. There are some others that come close and are a bit cheaper. With aluminum heads, is about a 10.1-10.5 CR OK on say 88 octane? Quote Link to comment Share on other sites More sharing options...
