Will a Holley 5200 off Ford Pinto fit 2.3 Isuzu engine?
No, a Holley 5200 carburetor designed for a Ford Pinto will almost certainly not fit a 2.3L Isuzu engine. These carburetors are designed for specific intake manifold bolt patterns and throttle linkage configurations. The Ford Pinto and the Isuzu 2.3L engines have different intake manifolds, making the Holley 5200 incompatible. You'd need a carburetor specifically designed and sized for the Isuzu 2.3L engine.
