Click on our sponsors link. They will have a delco that is original equipment. Get out the checkbook though, these things are high. Myself, I would just get a top post only delco battery, black. Most people won't know the difference.
DAVE,I have seen 3 lvl's of R59 Repro Delco batteries advertised over the past few yrs,a 650CC(Cold cranking amps @ 0 deg F),700CC,both std R59 batteries and a 750 CC version which i bouhgt called the R59HC.
I often wondered if the std R59 advertised as 650 & 700 CC were actually the same battery but hopefully the R59HC i bought is truely a 750 high CC amp battery.
If your running a BBC i would definately get the R59HC 750 CC battery if at all possible because the BBC's can use all they cranking amps you can get when starting a hot. This is esp needed when running apporx 18 deg btdc intial timing when running a perf cam like most of us are running.
Also,if your running a stock low output 37 amp alt have it rblt/upgradded to a 61amp while your at it. My local rbld'r had a kit to upgrade mine to 80 amp so i went for it but 61 amp is fine if your not running many accessoires. This will ensure you have a quicker/better fully charged battery when make mult stops & starts in a short period of time esp when at night with lights on etc if your running a high compression BBC that your trying to start hot with a stock HI TRQ starter.
Since you mentioned your restoring the car back to original i would install a new or restored volt reg and have your hi trq starter rblt to avoid hot starting issues to go along with the new battery & alt rblt /upgraded to 61 amps so you will have depndable starting weathter hot or cold.
