Fun day! Took Dawn dishwashing soap and an extended hot water wash to get the J-squared stink off my clothes :)
BTW, I think there was plenty more in that old girl. A set of valve springs with some spring and one piece retainers, I bet we would have got 20 more. No BS, that is unless the top rings all broke from hitting the ridge ;)

You going to flow test the heads the way they come off before you modify them?

I'm debating on what to do, but starting to come around to a less expensive project, using the factory heads with good valves and a good valve job. If I do use them, I will flow before/after.

No matter what, 44ft lbs with an intake/headers/carb swap is pretty nice. Totally doable by just about anyone with minimal funding.
Ross, you think that stink is bad? You should smell the ultrasonic water from my last carb (the burnt one). man.... I dunno if a shower will get rid of this.

It’s interesting that it made the exact same horsepower in iteration 1 as the Ford advertised gross rating. It’s interesting too that the 1966 Ford Pickup brochure shows a black & gold engine.

We were seeing the net numbers for sure before any tuning. The gross numbers came with a little bit of work.
Not sure about the color, but it appears that it's been this color all its life. Who knows.
Were all 66 engines black/gold? Or just truck?
-
1966 was the crossover year for blue engines. All the HP engines were black with gold or black with chrome valve covers until the change over to the blue. Joe-JDC

Remember these views because the next iteration will look quite a bit different.

I'm still surprised a bit at the low gross HP rating even from Ford. Didn't know it was that low as well as the torque. Woulda' guessed even back then it was closer to 250-260 HP. No wonder dad's 1965 station wagon was such a dog, even when brand spankin' new.
And yes, the pickup from the swaps was mighty impressive. Made me remember on Buzzy's near new 327 1967 Camaro (sorry) when we swapped in a hotter cam, aluminum intake and 4-bbl Holley (had headers already) it made a world of difference.

Great stuff!
The 352's I remember had pure flattop pistons - no valve reliefs. With the huge deck clearance and .400 lift cam they didn't need it.
I thought the valve reliefs came with the "high lift" cam, .430 lift or so instead of .400, in 1966 for cars, maybe 1967 for trucks.
Brent, can you check the cam lobe lift when you pull it out?
No need to really "degree" it, although I would do that even before pulling the chain off.
Just the lift will tell us which cam it is, either .400 or .430 lift, probably worn a little anyway.
On the colors, I have quite a few calendar-1965 ads for 1966 FoMoCo engines- none of the iron is Ford Blue, it's all still black.
Apparently the actual 1966 Model-Year CARS were all Ford Blue. Not sure about the trucks.
In general, the Gonkulator comes in a couple percent higher than these dyno runs, but it cant match that huge 344 ftlb from the BT intake. Must be a special BT 352-High-Torque intake, or maybe JDC ported it?
Gonkulator, with .050 deck, c6ae-r heads, and without water pump drive:

With BT CJ Intake (is that what it was?) and 650 Holley

I forgot those valve springs don't even have a damper, so if old and tired no wonder they wouldn't rev high enough.

I’ll degree the cam and check lobe lift when it comes out.
-
Didn’t degree, but checked lobe lift real quick. Took 30 seconds to check and 5 minutes to clean the sludge off and apologize to my dial indicator.
.2285” lobe lift.

Thanks Brent.
.2285 x 1.73 = .395 valve lift so I'd guess the old 1959-1965 .400 lift vanilla cam, 186-186 duration.
Unless that lobe was really worn.
My apologies to your dial indicator.

Were all 66 engines black/gold? Or just truck?
Very Cool!
ALL 1965 Truck 352's Were black with gold valve covers
ALL 1966 Truck 352's Were Corporate Blue
The 1965/1966 Brochures used same pics.
I currently have 7 1966 F100/250 Trucks. Starting with first couple weeks in production to last couple weeks in production. All were Corporate Blue and at least 4 of those had never been apart prior. I had a mid year 1965 F250 and it was black with gold covers.
I also had a 1966 F600 361 with only 5k miles and it was corporate Blue.
I have checked actual compression ratio on multiple 352's and they were all under 8.0 comp

Will be posting any new info to the thread in the Members' Project section.
