352 - 390 rods? C1AE-A????
Does anyone know if C1AE-A is a 352 rod or a 390 rod?
I was told that when I got a 390 crank for my 352 that I will need "390 rods" because they are shorter. Is this true??
So, I went by that. I bought new rods from my machinist that were supposed to be "390 rods" but I just found out they have the same part # as the rods that came out of my 352 which were C1AE-A.
So, If I have a 390 crank with the longer 352 rods, will that raise my compression since its going up farther?
Any help would be awesome. Thanks

Yeah I'm away from all my resource material but I believe those are the long rods. Hey, I've heard quite a few folks using them to raise compression but like Ratsmoker said the piston has to stay in the block, worst case run them .010" out of the hole.
And if you do run them that high, check your valve clearance especially if the cam is aggressive, you might have to cut the reliefs deeper. Don't let the CR go above 10.0:1

Guys, I don't know what rods are in the truck, but I was reading my auto machine receipt and found it said "Rods C1AE-A $96". So, thats what I'm going by. Whichever rods are in the truck work fine but I was just wanting to know. I'm using a stock-type .030 non-flattop piston. This is confusing.... eek. Maybe this whole thing is just the machinists error on paper not partswise.

Does anyone know how to determine what crank you have, once the crank is out? I looked for any markings and I can't tell. My buddy has a C7 # FE in his '71 (not original motor) And I need to know if it is a 352 crank or 390. The guy he bought it from said its a 390, you know how that goes. Any ideas???
