RE:390 rod bolts |

We're sure getting off on a tangent here based on K-SKI's original question but I think that's a good thing and I hope he doesn't mind.
As for rod bolts...it sounds like you're going to get into your 390 a little bit and I think it's a good idea to replace your 390 rod bolts with ARP bolts. I remember SPS bolt kits from many years ago, are they still in business? You're doing a full tear down and rebuild, right? I'm glad because then your Mach I 390-4V will be able to readily beat a 290 horse 351W '69 Mach!
What was Ford thinking when they detuned the 390GT to 390 "Improved Performance" for '69?! We've speculated that one to death a long time ago so no need to rehash it but I'd still like to know....oh maybe not.
Many have the current "theory" that the 390 rod is the way to go for a little higher winding street mill, this over the CJ rod with the larger PI/lo-riser/HP rod bolt (13/32"...memory here?). This theory is that the standard 390 rod has a little more material left in it around the bolt area and with the addition of ARP bolt/nuts, you've got a great rod. Now I'm not saying I subscribe to this theory, as a matter of fact, the rods in my 427 are the old C3AE lo risers with ARPs. These rods are identical to the C7 or whatever CJ/PI rods. But I am thinking about using a set of spare 390 rods with ARPs for my next project.
But I still have to get a fire built in my 427! It's going to happen this summer!! I've got the exhaust system done and now it's just a matter of reinstalling the front wire harness, a battery, coolant, and fuel! Any minute I'm sure. |
