Hey ya'll......I'm looking for the specs on the old 352. My friend just recently got ahold of one and he was wanting to know more about it.....Bore/stroke, stock cam specs, stock valve sizes, Combustion chamber cc's, Compression ratio, forged steel or cast iron crank, rod length, rocker arm ratios, Trannies that will bolt up to it, and most important of all, the horsepower/torque specs.


Thanks ya'll

 

Need to know just a little more, like what year, car or truck, 2V or 4V.

Without knowing more, here are the basics:

Bore: 4.00"
Stroke: 3.50"
Crankshaft: cast iron
Balance: internal
Rods: 6.540"
Deck height: 10.17"
Valves: 2.02" intake, 1.55" exhaust

Combustions chambers typically in the range of 67-72 cc for the 352.

 

41V heas and I'm not sure what year the motor is. Some where early sevenies is what the previous owner said.

 

1967 was the last year the actual 352 was made. But the 360's and 390's from the late 60's and early 70's had 352 stamped on the block.

 

[updated:LAST EDITED ON 09-Jun-02 AT 04:45 PM (EST)]If it really is from the early 70s, it is most likely a 360 from a truck, though it could conceivably be a 390. The blocks and heads are identical, and the blocks do have "352" cast into the front of them. The 360 has the same stroke as the 352, but the bore is 4.05" as compared to the 352's 4.00". The 390 is also a 4.05" bore, but the stroke is longer (3.78"). The early 70s 360s had compression ratios of 8.4:1, 2v intake manifolds and carbs, and net HP ratings somewhere around 175. The 390s were 8.6:1, made 30 or so more horsepower, but also had much better torque.

You can narrow down what it is by getting the block casting code and the date code. The casting code will be on the right side of the block toward the front. It will be 4 characters, a dash, and one more character. For example, it might say "C7ME-A." The date code is three or four characters stamped into a boss just below the place where the oil filter adapter mounts on the left front of the block. It will be a number, followed by a letter, followed by one or two numbers. For example, it might say "9F9" or "8B14" or something like that.

Find and post those numbers, and we'll tell you a little bit more about your friend's motor.

Also, how many bolts are there holding each exhaust manifold to the head? There should be 8, 14, or 16 on each side. Count them and let us know. You can also look for the head casting codes and post them.

 

No, we're sure it's a 352, but I don't know what year it is. The previous owner said that it was an early 70s but I found that kinda funny. It doesn't have 352 stamped in the front.

 

On the passenger side of the block towards the front will be the casting number which will tell you when the casting used to make that block was made. If there is no 352 on the front I have high doubts it is a 352. As stated above if your block has 352 on the front it could be any FE but what makes you sure you have a 352? Did you mic the bores and measure the stroke? This is the only way to tell.

I'm with RS on this one. What makes you "sure it's a 352"? You can't tell from looking at a FE whether it is a 352, 360 or 390. If you find all of the casting, part and date codes, you can get a pretty good idea, but it sounds like you don't even have those. You need to either open it up and measure the bore, or inspect it closely and find all the codes cast or stamped into it. In any case, the guy who sold it to you obviously didn't know what he was talking about, so I wouldn't trust anything he said.
