I just tore down what i thought was my 390...
Im making sure its a true 390... please could someone post a list of what bore and strokes make what?
I ordered a thousand dollars worth of parts for the truck last nite, and tore it down today...
All I have to do now is buy rings/bearings/pistons and I wanna make sure before I buy them
Please let me know..
standard 390 bore is 4.050 and stroke is 3.78"
standard 360 bore is 4.050 and stroke is 3.50"
standard 352 bore is 4.000 and stroke is 3.50"
standard 410 bore is 4.050 and stroke is 3.98
standard 428 bore is 4.130 and stroke is 3.98
Measure the stroke first to be sure which crank you have. If it is not 3.78" then it is probably a 360 or 352. Good luck!!
I will do... as soon as I get that far
I built a matching set of heads for it C6Ae-R's I think... (forgot off top of my head)
Mine had mismatched heads and these heads are really nice so I used them.
They are ported and has a valve job.
Anyways, I'll let you know when I take the oil pan off and remove the pistons and such
Im sure its a 390 now tho, but just to make sure
