318 2bbl manifold swap with OE cam - worth it?

We ran our bone stock 74 Dart years ago. It had over 100,000 on it. Stock 2bbl 318 with single exhaust. It ran an 18.3. Highway gears, one tire fire etc.

We wanted to get my wife some seat time while we built her a 360 so we purchased an Holly 600Dp, a Weiand Xcellerator (there are better choices for this application) and a set of headers and dual exhaust. It ran a 16.2 and the one tire fire was really obvious. It went mid 15's with a suregrip and 4.10's. We were careful to only purchase parts that we could bolt onto the new engine so we didn't throw our money away. Ran that thing all summer and had a blast. Probably put almost 100 passes on it before the 360 was ready and we just bolted our intake and carb onto the new engine.:cheers:
