352 360 horse

[Royce]

This one is going on the pump Thurs..
It is a stock rebuild of a 360 horse 352 as near to original as I can make it. I have the correct heads, carb, intake, dual point distributor. Cam is a copy of the 406 cam from Holman Moody which most people agree is what came in the 360 horse.. I am going to run through the shorty cast headers into 2.5 inch pipes no mufflers
Deviations from stock: 4.03 bore, about 1/2 point shy on compression.  Previous owner has put  CJ sized valves in the heads.  I will run it on 110.

I plan to optimize the air fuel on the original carb, dial in timing, and maybe try a couple spacers... Then I plan to switch to a Autolite 1.19 carb just for fun.

Guesses are welcome, however no prizes will be given..  Unless I can get Steve Peasley to volunteer for the county fair dunk tank.. Then i could give out a dozen free tries to put him in the drink.

Frankly, looking at the carb and intake manifold, no way this makes 360 horse.

So the cam is the 306-306 advertised, 228-228-114 at .050, .298 lobe lift?

Compression ratio?
Deck clearance & gasket thickness?
Piston-to-Bore & Bearing clearances rods/mains?

I ran spacers on the factory 8v LR intake & it did NOT like an open spacer, the air slamming into those 4 little holes really upset it.
I'd try either a 4-hole or a clover-leaf, something to smooth the flow as it slams into the intake.

This will be fun- especially the peak torque with those high-tech C0AE-D chambers.

Looking forward to the results...

Nice, I’ve always hoped someone would build and test one someday.

The least you could do is put up a shrimp cocktail for the winner

Well  lets see if I can fill in some blanks  Compression ratio 10.1 I had to deck it .030 and cut the head .030 to get there.. Piston is .030 down the bore and I have a .020 head gasket Bearings are .0025 rod .0030 main. Did not measure the piston to bore clearance    Relied on the machine shop and I forgot the spec. I have a 4 hole 1 inch spacer and a 1 inch clover leaf spacer to try

I won't be at all surprised if the Autolite 1.19 outperforms the original Holley.I also won't be surprised if you meet or exceed the factory rating.

What ring pack did you get with the pistons?  That will have an affect on the results. 

328 hp

You are close to my Guess Joe.. The rings are the old 5/64 style.  In fact given how short of the 300 horse rating the standard 4bbl 352 was. I would not be surprised if this one was under 325 hp..

[Tommy-T]

Any other "love" given to the cylinder heads other than bigger valves and milling?

Good luck and I'm hoping to see 360hp.

Cool Build!
Not old enough to remember 360 hp 352.
I would guess 340 hp.
I would also guess this will like plenty of ignition advance too.

361

[Royce]

Nothing done to the heads beside bigger valves and milling..   I hope my pessimism on the horsepower is proven wrong

[blykins]

It should at least make 1 hp per cube I'd think.

[Heo]

347 is my guess
