My mechanic at my home dealer, has just about convinced me to doing this kit. It comes with 10.5/1 forged Pistons, and 585 cams. Installed, the price will run me about $1,600. His dyno sheets, on prior builds, shows 100+ hp, and 121+ tq. Anyone have any experience with this setup? I already have the STP. He also wants me to buy the adjustable pushrods and S&S lifters( I think lifters). This will put me right at $2000. The kicker is, I have an extended warranty. The dealer said he will back his work, and will honor the warranty, if needed. I saw the power band on his dyno sheet. It basically mirrors my power band I have now, but at a higher rate. The kit comes with perfect fit pushrods, and I would just use my stock lifters. The sales manager and the mechanic both say if I don't do the extra parts, I'll be back later, to have it fixed. I actually trust these guys. Is there a better way to spend $2000?
