Q i want to make 1,000+ hp ! what is needed with this kit to make is happen ? i'm running a whipple 2.9 sc , what compression and what cam do you recommend ?
Asked by william grier on February 7, 2021 8:45 amA We would start with a totally different rotating assembly, look more at the Callies rods, crank, custom set of Diamond pistons. Shoot us an email firstname.lastname@example.org with specifics of what you are wanting to do, what supporting mods. As many details as you can think.
Q With the SS4 cam and stock GPI ported LS3 heads is will there be enough compression to run e85 with these pistons?
Asked by W on December 7, 2020 12:23 amA Yes, will do well on E85, can always mill the heads or run a little thinner head gasket to bump the compression some.
