ENGINE CUTS OUT AT HIGHER RPM'S

1976 Ford Maverick • V8 2WD Automatic • 150,000 miles

1976 Ford Maverick mileage: 150,000. I had a 6 cylinder put a (89) 302 in car. Holley carburetor and fuel pump. The engine will idle fine at mid to high rpm's, the engine starts cutting out like there’s a rev limiter in the ignition system, which is stock. The engine has 10 half to 1 compression, larger then factory cam.I was told it is many different problems!Fuel system, ignition system or valve train. Any input you can add could be a big help to me

Check the fuel pressure with the engine running and when the problem is occurring. You could be having insufficient fuel being supplied to the engine and may need to replace the fuel pump.

Checkyour distributor plate as they wear, the vacuum pin wears as well as the pivot. It may bethat. Anddo your regular ignition checks and fuel pressure as well as volume.
