The difference between LS9 and (L92/LS3) heads is the type of material. LS9 heads were designed to handle higher boost, because they used a different type of material. Can you install an LS9 head on LS1 block? No. The bore size is smaller on LS1 as compared to L92/LS3.


I do have a complete Harrop TVS2300 with Wegner accessory drive and all the accessories for sale, but it is for an L92/LS3/LS9 port. Yes, it work in 67-69 Camaro. I switched to LS9 Supercharger setup. The Wegner accessory drive has 2 different sizes of pulley. The small pulley is designed for engines that have custom forged pistons, crank, etc. I tested mine at 15psi in 2009. While the larger pulley is designed for stock engines. 8 psi.

Magnacharger did design an LS1 TVS2300 supercharger kiit. The kit is described as a Hybrid TVS2300, but Magnacharger must have modified the kit with different ports. That kit is only 6psi.... If you pulled this from another car, then it is better to build around a fresh engine.

Just a little fyi but Harrop does make the 1900 and 2300 TVS units for a cathedral port head. The only style TVS they make that doesn't work on that head design is the new FDFI style.
