Are 360 heads the same as 390?

Looking for an answer to the question: Are 360 heads the same as 390? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are 360 heads the same as 390?

The 361 had the 332/352’s 3.30-inch stroke. However, it had a larger 4.05-inch cylinder bore—the same as the 390 to come later in 1961. The 360, 390, and 410 are grouped together because they share the same basic block with the 4.05-inch bore.

The only real difference here is the crankshaft. The 410 Mercury is a 428 crankshaft in a 390 block. The 360 for trucks is a 352 crank in a 390 block. Where this block varies at all is in the area of high-performance applications.

Differences lie mainly in combustion-chamber size (compression ratio) and port size. Port size doesn’t vary much among these engines. For example, the 390 High Performance head has the same valve and port sizes as the early 427 High Performance head. This means you don’t have to pay 427 prices in your quest for power.

Basically, all that is required to make a 360 into a 390, is a 390 crankshaft (3.78" stroke compared to the 3.50 stroke of a 352-360), the shorter 390-428 rods, and 390 pistons. The 352 & 390 have the same bore, but the pin heights are different.

Yes you are correct and to add to that, the low compression has nothing to do with the heads. As already noted, all regular FE engines (352, 390, 410 and even the standard 428) usd the same heads in a given year. That is to say a 67 352 and a 67 428 will both have a C7AE-A heads or a 69 360 and 390 will both have the same C8AE-H heads.
