One wire lock-up, 4 spd automatic w overdrive into A-body.
Well winter and spring have come and gone, and I realized I never posted any feedback on how the swap is performing, so here it is.
The Extreme Automatics transmission works flawlessly through all the gears and the 3000 rpm lock-up torque converter makes it feel like it has a 5 speed automatic when it is engaged on the highway. The install is undetectable with the only hint it's not a stock transmission being the shift pattern sticker on the aftermarket shifter.
I highly recommend this upgrade for those seeking both performance and comfort. It was a lot of work, but nothing was hard to do. Precision of New Hampton has the measurements for the torque converter when using the Reid Racing bellhousing if anyone is interested. I like the look of the bellhousing as opposed to the adapter plate, and am happy with the overall conversion.
I am running 3.91 rear-end gears, Nitto Drag Radials and an injected 408 Magnum that is putting out just south of 500 HP. I built and cammed it for torque and street-ability. This engine, trans and rear-end combo are nothing short of incredible, and are super fun on the street. The car nearly dead hooks out of the hole when the tires are warm, and the gear ratios are awesome for both daily driving and drag racing. The closest track is over 2 hours away, so I haven't been able to time it yet. Being its a convertible with only a partial cage, I will likely only get one pass before being black flagged because it is too quick for the rules. The only thing that has out-pulled me yet on the street was a modified GTR. That thing was amazing!
Swapping over to fuel injection, installing this 200R4 overdrive and upgrading the chassis, suspension and brakes have transformed this '68 A-body Barracuda convertible into a true modern performance vehicle. The dramatically improved drivability, mileage, acceleration, braking and handling are complemented with the convenience, reliability and comfort of EFI, overdrive and air conditioning. If an of you are in the San Jose area you guys have an open invitation to feel the difference this modern technology has made to the simple joy of driving in this beautiful drop-top American classic. It's simply awesome now!
