thanks for all the great input....

on my 75 the specs call for a 42 amp alt w/o a/c. with a/c--61 amp. when i got my vette it had a 55 amp on it which i replaced with a 75 amp. as my a/c is not presently connected technically i have enought to run fans but as i want to reconnect a/c at some point , i installed a 100 amp alt. if memory serves me right (sometimes it does work), the fans specs say they draw 35 amps. hope this helps.

So, its safe to say I could get away with running a 63 amp alternator seeing as my car does not have A/C or any other heavy draw items?

i would say you are pretty safe. as far as what i was told about  wiring, it would be okay to put in higher alt as the regulator will control it plus you are not going to be under the constant draw all the time.  as a matter of fact i decided for now to leave the 75 amp in until i get a/c working but will have the 100 amp for then.

If you order from them, make sure you go with the "Black Beauty" (I think that's what they called it) option.  They paint the radiator black and it looks more like a factory model.  They say the way they do it, it does not effect cooling at all.  I wish I had spent the extra $35.  But other than that, I'm very happy with my DeWitts.

I wanted a Corvette my whole life, but I never dreamed of all the wonderful people I would meet because of it!

i didn't get it with that option. as i am not going the route of making it totally original and i am adding a lot of chrome pieces to sort of dress it up the aluminium kind of fits in the picture. i feel like my brother does, who restored a 66 convertible (don't really want to sat the name here) mustang. he feels that he put in what he liked as he wants to drive the car and is not looking to see how much he can sell it for. it is a beauty. i am not going to make my vette a museum piece as i too want to drive and enjoy it and not just sitting around. that i'll do when if i ever have the good fortune of owning more than one corvette.

I put a 100 amp in mine and did not alter any wires

The problem I had with the electric fans & air is at idle the voltage would drop with a 100 amp so I had a 160 amp built ..no more voltage drop. Also since I installed the TKO 600 my rpms tend to be much lower than with the 4sp. Also rewired the complete car.
