Distributor recommendation - 1990 K3500 454 Manual

[jrhthrd]

Hi everyone - I recently bought a beautiful 1990 K3500 w/ 454 & 4 sp manual and 70,000 original miles. The previous owner used it to tow his race car, and added an RV cam, headers and edelbrock manifold under the stock EFI, otherwise it appears stock. It runs ok, but acceleration is not smooth, even after plugs, wires, cap & rotor. At this age/miles, and after a bit of reading, I'm inclined to replace the distributor, fuel pump/filter and the fuel injector itself. The 454 will eventually get new heads for better flow, but likely won't exceed 500HP or 5000RPM.

Looking for distributors, I see several with a coil in the cap. My truck has a separate coil. Are these interchangeable? Can anyone recommend a great distributor for this mild build?

Thanks for your thoughts/advice!
