Yup, it's on the road, and so far it seems good and strong. Need to get some exhaust work done and put on some more miles before I can really put it through it's paces, but with about 15 miles on it the 0-100 km/h time was ~16 sec (vs. 19.3 with the 3FE). I take that as a 20% boost in power at the rear wheels, and it certainly isn't broken in yet.

It seems to have much the same powerband as the 3FE, coming on strong at ~2500 and building up through 3500 anyway. Can't wait to put the boots to it once all has seated well and the exhaust is sealed.
The issues we found on start up:
1) The fuel line to the cold start injector was seeping a bit (onto the exhaust

), just needed the banjo bolts snugged up.
2) One (non-stock) bolt on the thermostat housing was seeping coolant, replace with a stock bolt and a touch of pipe-dope, all is well.
3) Started to run hot. Thought the fan clutch was not kicking in... but after a while it did and the temp dropped. Think this was because I left the fan shroud off for the initial start up, so the clutch wasn't seeing the heat to engauge. Hasn't run hot since adding the shroud.
4) Idle is excessively high (1500 rpm in neutral once warmed up). Haven't corrected this yet. The ISC valve tests out fine (though perhaps the wiring to it is pooched?). Will have to play with the wiring to the ISC valve and see if the situation changes, or it goes away as the computer learns the new engine. If neither solves it, I guess I'll have to open up the idle bypass screw in the throttle body and cut down the amount of bypassed air.
5) The fuel cut feature (when you back completely off the thottle at speed) is much more pronounced than before.... perhaps related to the larger TB bore/plate size?

Or maybe I need to re-check the TPS set-up (could help with idle too....).
6) Valve cover is tight to the firewall seam when pulling it off to adjust valves. I needed to bend the seam up to make room.
7) Seems to be another slight coolant seep I need to track down, dripping down off of the relay rod.
