In stock form, these engines are decent performers but they have much more to offer. And now with the Thumpr GM LS Cams you can have all the efficiencies delivered by this modern engine platform with a head turning ?old school? hot rod sound and serious performance to back it up. The new Thumpr GM LS Cams are compatible with both arbureted and re-tuned electronic fuel injection (EFI) engines and do not sacrifice anything in durability or street manners.
