Aside from the porting, which you can't just look at and "reproduce" and get the same results, I doubt there will be much to see in Blair's teardown. It's not like Kaase's out-of-this-universe bronze combustion chamber/head gasket idea, that resulted in killer power. So I'd be prepared to be let down if anyone is looking for a smoking gun as to why the engine performed the way it did, and hoping they can repeat the results. The devil is in the details, and those are not readily apparent when just looking at an engine.

The C4 heads have been known for a while to be the best factory FE head out there, aside from the performance designed MR, HR heads. So that shouldn't surprise anyone. Might be interesting to see if any port filling/raised runners have been done though. Other than that.....yeah, it's just a bored out 390 that kicked a bunch of Cheby butts. Nothing special  8) 8) ;D

What was the reason for all the various pipe fittings on the thermostat housing?


Pretty sure that's just so it can be easily adapted to the dyno water cooling. Time is pretty precious when getting everything ready to go.

Barry said the dyno was pretty accurate, but I'd be curious if any changes were made during the allotted dyno time, like jetting etc, or if it was good to go as-is? I believe there's a fairly significant elevation change from Tennessee to Cleveland, although it was pretty hot and humid this week in Ohio.

Does anyone have an update on the tear down inspections?

As with most engines the secret sauce is in the heads.. Some things will be neat to look at in Blair's motor like what valve sizes and valve train parts he used. You should be able to look inside the port and tell how much he changed the shape and also what was done to the combustion chamber. No welding or epoxy was allowed in the ports so they are as cast with no holds barred porting. Kaase tried some tricky stuff with the valve seats on his BBC but was bummed that it did not help at all..
They keep trying to write the rules to make scrubs competitive, but Fords win nearly every year

must of been those .046 over Pistons on the smoking gun 390 , :) great job BP , " the little 289 that could " sure is impressive too , would be curious on the .046 Piston was just what was needed or part of the Math ?

One thing I noticed with the dyno cell during testing that I'd like someone to explain....

There was no intake hood on any of the engines in the EMC testing cell. Usually you'd expect to see a dedicated hood for engine supply air with an air turbine to collect data on airflow rate. Because of the air being exhausted out of the room, you'd expect the room to be slightly negative pressure (.5" to 1") and inherently the engine supply air in this situation would be slightly less than expected. Why do they run them like this during competition?

The JE Pistons dyno is housed inside their mfg facility and does not use outside air. It pulls from inside the building.. There are two huge exhaust fans in the booth and they actually do pull a slight depression.. It is very different from most dyno cells, but then everyone runs under the same conditions.. The dyno adjusts the correction factor in real time to reflect heat humidity barometric and altitude. Correction factor was between 1.072 and 1.079 when I was watching it.  The air turbines on older dynos have been replaced by wide band oxygen sensors to monitor A/F ratio

Hopefully their weather station is inside the cell? Otherwise they're accounting for the wrong baro pressure. Agreed though, everyone is running on the same dyno so all is fair.

Just heard from Blair. Tear down went as expected. He is the official winner. So proud of him.

We are not worthy!  Congrats on a hard job well done. ;D

I'll be the latest to pile on and give BIG congrats to Blair!  What a fantastic result.

He did the 482 for my Galaxie and I've been very pleased; not just with the finished product but the excellent before and after-sales help and advise he has provided.  I just need to call or text him to get the benefit of his years of expertise and experience, no matter how small the issue is.

It's a very strong case to continue to support the engine builders and vendors who contribute to this forum!

Thanks very much to all of you for the kind words.  It was good to go back to the contest after 10+ years of watching it from a distance.  It is a great experience with a bunch of good people.  As with all of this, the relationships last longer than the few minutes in the spotlight.  Happy to win it, but long term friendships and mutual respect for the other guys will stay around for the long haul, and that is what matters in the end.  I appreciate the support of this forum. The FE ruled this time!!!
