When it came to timing, we started with 34 degrees of total timing and varied it two-degrees advanced and retarded, but found out that the engine liked 34. The valve lash was set at the recommended .016 inch and .018 inch.

After several hours of tuning, we finally ended up with 519.9 horsepower at 6,000 rpm, and 509.7 lb-ft of torque at 4,000 rpm. Like we said, we left a little on the table by not getting in deep with machine work, and the dented 15/8-inch headers we used on the dyno surely cost us some power, but you get the picture. By the way, we placed a challenge on our website for you guys to guess how much horsepower this engine made, so check out www.moparmusclemagazine.com and see who won the horsepower guess.

A New Home
When we got the engine back to the shop, it was time to place it in its new home-Project Valiant Effort. We needed to make a few small changes for the engine install. Things like the 21/2-inch exhaust already on the car were perfect for our original engine, but this thing needs to move more air. Not only that, but we wanted to make some noise. To that end, a Flowmaster Universal Scavenger X-pipe kit and their Super 40 mufflers came into play.

When you need to transfer a lot of power through a clutch, just any old clutch won't do, so we contacted McLeod Industries for one of their Borg & Beck/Long style of clutches. The McLeod flywheel is an SFI-approved unit, but for added safety, we also contacted Quick Time Performance about one of their bellhousings. The Quick Time bell is not simply "stamped" from a piece of steel. The QuickTime "cone" is spun, and this allows the QuickTime Bellhousing to be the most dimensionally stable bellhousing available. Also, unlike other "stamped" bellhousings, the QuickTime bellhousing also doesn't take up any more room than a factory bellhousing, so you know it will fit

Finally, we know that the Valiant's hood is going to be in the way, so for now it's removed. It definitely looks old-school without a hood, but we might get a fiberglass one to put on the car. The only thing left is to take the car to the track, and after some break-in time, you bet we will-we'll let you know how it goes. Until then, check out the video of the car proving its "streetability," and go along for a ride with our "Old-School" engine at www.moparmusclemagazine.com.
