Heater core supplied by throttle body? - Pirate4x4.Com : 4x4 and Off-Road Forum

350 carb -> 454tbi swap.

It looks like the heater core is supplied by a large metal tube coming off the Throttle body. The tube is almost rusted through in spots. This sound right?

Also The thing has a external coil. External coils and mud trucks dont mix. Can it be converted to the kind with the coil in the dist. cap?

I used an early 80's corvette distributor which allowed me to use my HEI coil. Its a full size distributor cap but screws to the distributor instead of the push clips, but can use and old school top coil.

That tube coming out of the throttle body works much in the same way as a carb pre-heater.. Basically it just routs coolant through the throttle body to keep it from freezing up. Some people just by-pass it but thats up to you.
