willie Posted March 24, 2021 Posted March 24, 2021 Is there a difference between a 350 car alt and a 454 car alt? I know they have different amps and should show it on the case somewhere. But will they mount up from 1 car to the other? What amp does the 71SS have with a/c? Tkx Quote
714024SPEED Posted March 24, 2021 Posted March 24, 2021 Hi Willie The alternator's are the same between big and small block. I'm not positive about the amps but I think it may be 53amp. I sure someone will help confirm that or not. 1 Quote
jft69z Posted March 24, 2021 Posted March 24, 2021 It should be either a 61 amp, or a 63 amp if it has the 'K85' option on the build sheet. Dennis just ran into this last month and the charts seem to support that answer. Physically it should be a direct bolt in. Quote
willie Posted March 25, 2021 Author Posted March 25, 2021 Ok great !!!! Thanks Guys, i checked my build sheet and it does NOT have a K85 so the small block one will fit. Tkx Quote
wallaby Posted March 28, 2021 Posted March 28, 2021 They all mount up the same. There might be a difference in the "clocking" of the wire connections. but that can be changed easily. Ignore the amp ratings for rebuilt alternators, they grab a case from a pile and fill it with the average stuff. Who knows what case they grabbed. Quote
