hows it going guys and girls, just a quick question. A mate of mine has bought a XD V8, but we dont know if its a 302 or 351. Is there anyway to tell the difference by looking at them? thanks in advance

Oh, there was a recent thread in here on how to identify a 302 vs 351 [[[Windsor]]]Cleveland. Use the search function.

Basically, pull a spark plug and use a rod to measure the stroke. Externally the engines look identical.

If it is an original factory 8 it will have the following engine codes on the id plate:

ENGINE CODE TO 1/81
4.9 - P
5.8 - T

ENGINE CODE FROM 1/81
4.9 - P - All states except NSW
4.9 - B - NSW
5.8 Manual - T
5.8 Auto - T - All states except NSW
5.8 Auto - H - NSW

Hope this helps.

Is it a factory V8?

Unfortunally ya can't tell by looking at it, measuring the stroke is the only way, unless ya wanna drop the sump, it say's what it is on the crank. :)

Check the chassis number against the block number.. if its the same, then you're running the factory V8.

302 vs 351C, the 351 has a longer stroke, therefore it requires a taller block.. see if a workshop manual lists the different deck heights for the two motors, then measure them accordingly..

diskokin6,,,its only the stroke thats different, not the block... You can take the crank/rods/pistons from a 351c and drop em in a 302c......
I drive a holden and even I know that

Your gettin your Clevo's and Windsors confused buddy !!

yeah, sorry people. I know some stuff about the V8s, but obviously the finer details of deck height between the different engine families continue to escape me... I'm more of an I6 bloke :)

Technically a 302 is Australia's version on the American 351, which was the same motor as ours. I don't think the 302 Cleveland was available in the states. When ya looking through perfomance magazines for the States there is never ant mention of a 302 only in the Aussie ones.

Crank, con rods and high comp heads are the differences between the two.

I believe a 302 has a 3.5" stroke, where the 351 has a 4". Using a pencil (about 7"long) down the sparkplug hole and hand crank the motor, calculate the amount it moves, either 3.5 or 4 inches.
