Speed Demon 650cfm Carburetor

Description

Speed Demon 650cfm Carburetor, by Barry Grant Fuel Systems.
This is one of the early carbs before Holley bought him out. It has the Drop-Leg annular boosters, Vacuum Secondary and Electric choke. This carb came off a 9:1 454 Big Block Chevy. It is jetted for 6000' elevation here in Colorado. It just isn't quite enough cfm for my monster motor. It currently has #58 Jets on primary and #68 jets on secondary and the silver plain spring in the vacuum can. It uses all the same parts, jets, springs, gasket sets that work on Holley carbs.
I do have a few sets of jets and the remainder of the vacuum spring kit to go with.
