What is ERL? Is that a company?
When you say people have issues with the 4.1 inch stroke on the stock LS3, does that mean that it doesn't develop enought torque and by making it less square the engine is a better torque performer?
Who can do this kind of work? Are we talking Hennessey, Ligenfelter, SLP?
Relative to the comment from willhe64, I quoted $15000 for a complete LSX 454. Thats what I thought I saw in one of Chevy performance books. It is rated I believe at 740 hP.
I'll check and get back to you guys.
