Help Needed - Identifying Alternator for SBC 5.7L

[jjkeen]

Thanks Guys, I'll do some homework and find out which one fits best now.

Cheers

The one that is shown by Roadcraft should be fine, if you think it will fit your block, may have to use
spacers to get purfect pulley alignment .
Seventy Amps should be suitable for most applications, not so for high draw stuff like electric heating etc,
Will be fine for most electric fans though .
As for wiring, that's the really easy bit although it may need altering a bit .
Unless the original alternator was designed to be part of the engine mount set up, that is the case with a
lot of modern vehicles, you should be good to go .

Have a look at Roadcraft.
If you have 3 wire or single wire.

I would also look at this company and best to call them. Highly recommended.

I would have thought the one you show should do the job .

Do you have 3 wire or 1 wire ?

Hi everyone,

I'm hoping to get some advice on replacing the alternator on my SBC 5.7L engine. I've removed the old one, but unfortunately, it lacks any identifying markings to determine the required amperage for the replacement.

I came across this alternator on ProForm Parts:

https://proformparts.co.uk/products/alternator-gm-73-86-with-internal-regulator-gm-bowtie-logo-chrome-chevrolet-performance-parts?_pos=18&_sid=538c896c2&_ss=r.

I'm unsure if this would be a suitable replacement for this engine.

Would anyone have any recommendations or if the linked alternator is compatible?

Thanks in advance for your help!
