Upgrades for 402 LS

[Steve1968LS2]

That's so pretty I'd be afraid it wouldn't like a cam change. Sure on paper a cam change should do better if spec'd correctly but that doesn't mean it will.

Steve, why didn't you have a "custom" cam spec'd when you had the 402 built? Comp lists the lobe numbers online. They did have them in the back of the master catalog for a long time. I used to laugh at all the people selling "custom" cams to customers for a huge mark up. They went through such secrecy to hide the cam info too. All they did was flip to the back of the catalog and order based on lobe numbers and told Comp what LSA they wanted it on. Truly custom would mean they spec'd the lobe design which very few really did.

We did have a custom cam in the old LS2.. when it died from an oil failure we had to rush an engine together.. at that time it was almost 2 weeks for a custom grind so we picked the best from thier "off the shelf" offerings. Not sure if the lobes were one-offed but the cam was designed by COMP and worked well, just no time to do it on the new engine.

And it's true that there are very few "truly custom" cams.. most are just a mix of existing lobes.
