Another Mopar Off My Bucket List - Barracuda Fastback
I guess the house is on hold for awhile. Before my son showed up I already had the new k-member and disc brakes assembled on the Charger so we immediately tore into the Roadrunner when he arrived.
First things first. We decided to make the change over to the Evans waterless coolant so we drained the engine and flushed the system with water. Then we spent an hour blowing all the passages, radiator, and heater core out until they were near dry. Despite the limited mileage on the motor there was already some rust and sludge in the water passages. The system has always had a 50/50 mix of high quality antifreeze. I'm glad we're going with the Evans.
The new ECU from FAST won't be here for a few more days so we're hoping to have the rest of the car done before it arrives. The first step was to disconnect the wiring and fuel lines. Then we pulled the intake and heads.
Because the engine only has a few thousand miles on it we didn't have concerns about cylinder wear. The bores are clean and still show a nice cross hatch pattern. We continued to blow out the water passages after the heads were removed.
I had cleaned up the combustion chambers and ports the best I could when the heads were slated for the Charger. It was about 10 hours of work with a Dremel tool and emery cloth.
There were a number of other components we'd picked up for the Charger that cannot be used for it now that we've made changes to our head selection. The COMP Ultra Pro Magnum roller rockers and matching pushrods needed a new home. If we'd sold them we'd probably had to take a loss on them so we chose to use them here instead. We'd also purchased a set of ARP head studs. Apparently they won't work with the Max Wedge heads so we decided to use them now too.
The tti headers have 2" primaries. Although we could have held them back for the Charger, the Roadrunner's stock exhaust needed to be upgraded. The header flanges would not clear the head studs without notching. - And even still, we had to use a few bolts to clear some of the primary tubes. We test fit each of the components for compatibility before installation.
