'68 Barracuda Formula S Fastback Restoration
Engine and Transmission Build
I have 3 340 engines including the original engine for the '68 Cuda. Having collected junck yard engines in the early '70's and hauling them around for years in unassembled condition, I decided to build them all in the late '80's. At that time, Ed Hamburger had lots of Mopar parts available for very low prices. I built the two spare 340's with 0.020" oversized Sealed Power Hypereutectic pistons. (2332P +020). I never bore engines more than absolutely necessary. Both engines were line-honed and balanced. The first engine was built with a MP 284/484 cam and adjustable rockers (from a 273). This engine pulled to 6500 cleanly and dynoed at 320 RWHP (atmospheric corrected from 5800 ft) Not bad for a mostly stock engine.
But in my quest to reduce weight, when possible, I went with Edelbrock Performer RPM aluminum heads for the second engine.
I will be using a TQ carb on a Performer intake manifold as the TQ is the best street carb available. I have 6 different one but the 440 version (6322) has the highest flow rating so that is the one I will use.
The Edelbrock heads have different mounting surfaces than the '68 340 heads so I have to use the '70+ water pump. This takes up 3/4" more room in front of the engine making radiator selection difficult if you want electric fans. I have yet to choose the radiator for this build.
