They Say All Good Things Come To Those Who Wait. We Didn't Want To Jump Into The LS Retro Market Until We Had The Biggest And Baddest 454 LS "Pump Gas" Engine On The Planet. Not Only Pushing 765 HP At A Mild 6400 RPM This Hydraulic Roller Engine Delivers A Torque Curve So Broad And Powerful That You'd Swear You Were Running An Engine With A Blower On Top! This Is The Best Torque Curve I've Seen In A Normally Aspirated Engine In All My Years Of Engine Building.

Why Buy A Carburetor From Us?

Yes, you can certainly purchase a stock carb from the big mail order companies but we've seen carbs out of the box down on power as much as 40HP and between 15-20HP is common. That's why we disassemble and blueprint EVERY carburetor before we ever bolt it on your engine. We then tune, adjust and jet your carb on your engine so you get every ounce of power that you paid for.

Even if you're considering one of our Engine Kits or simply looking for a replacement carb, the same blueprint work is done and we dyno test it on a comparable engine to yours before it ships!
