"Brand new" 1970's build with Aluminum Rods - 07/28/17 10:03 PM
Hey everyone. Please ignore the low post count- been with the board since 2000 but lost my ID after not logging on for awhile during the dark "Elvis" and "70 Daytona" days.
I have a 383 that was built in the 70's and never fired that I put 40 passes on in the late 90's. It needs bearings (don't ask) and has aluminum rods. I seem to remember reading on the board (maybe by Fast68) that there can be issues with getting proper torque on the rod bolts if "old style" alum. rods are taken apart and re-assembled. Is that true?
This is a nostalgia build that I would like to stay true to and use this motor to get the car going again and making passes. It had great oil pressure, ran well, and looks good inside. That said, it is a 383 of unknown build quality and has boat anchor Jahns(!) pistons and probably needs a cam. I'd like to use it but it may be better to go in a different direction.
It has 915 iron heads that again have no time on them that I would like to port into the 260 cfm range (very committed to factory looking heads so Stealths could work). I understand the cost/benefit of iron vs. aluminum but I think these heads are still pretty fresh with very low miles so I might get away with minimal work other than the porting.
So- are the rods a problem? I know that 200 or so passes might be it for them. Am I nuts to put any money in it? Looking for opinions- be gentle!
