| Rods - std. or CJ? |
| By Mike McQuesten - 09/20/2001 12:54:02 PM; IP 206.193.0.124 |
| I'd like an opinion based on facts from some folks. My question is with regard to the standard 390/428 rod vs. the 427 low riser/428 PI/Cobra Jet rod. A few years ago there'd been no question about which was the better high performance rod. Now I'm hearing from some who purport to be "in the know" that the better HP choice is the standard rod with ARP bolts. This is because the standard rods from around 1966(?) up were actually the same rod as the '27LR/PI/CJ rod except they were not equipped with the larger bolt/nut. Thus the standard rod has more meat left and that the ARP bolt/nut takes care of the weakest link. It's a fact that the ARP bolt now produced for the CJ/PI rod is designed to fit in the place of the larger bolt but is reduced down to the size of their standard bolt for the FE. I'm being told that this makes the CJ/PI rod more prone to failure than the standard rod equipped with ARP. So I'm just wondering what you think. I am running a C3AE 427 rod with ARP kit in my current 427 spinning on a C5AE $ sideoiler steel crank. I have a couple of sets of standard 390 rods that may be used. I do have a mixed set of C3AE/C6AE/C7AE (all PI/CJ/LR'27) rods that I may use too. This all for an "engine in planning". All things being equal, good rod prep, etc. What do you think? |
