Well, it's taken a while to get to this stage, but today my 406 fired to life. I had a change of plans in that I decided not to use the ceramic base lifters and went with a set of Comp dumbbell lifters instead, which also dictated a valve spring change to suit. I also managed to get a 500cfm Holley to use on the centre carb. The engine was run on a local dyno. I was a bit nervous about the cam break in, but all went okay. I didn't get any pics of the engine on the dyno, but here are the dyno charts and graph.
With running 3 x 500 Holleys, each with 50cc accelerator pumps, the A/F ratio was going way rich as all the carbs were opened up. This is shown by the dip in torque at low rpms. Due to this, the pulls were started at 4000rpm as the mixtures were starting to clean up. Tried a few timing changes, but best power was made at 33-35 degrees. The mixtures were still a bit fat at higher rpm, but I ended up running out of time. Still I was happy as it started, ran, didn't break, and only had a minor oil leak out of the rear manifold to block join. And to top it off, it made 545hp on our premium pump gas, with the potential for a few more hp with more carb tuning. And that big flat torque curve should help get my Galaxie moving.
