Came across a smoking deal on a Holley TBI, seller said it was a 502-6, now that I have it in my hands it doesn't appear to be a 502-6. The bores are not 2" and I can't reference the numbers on the casting, if anybody could decipher---

80373 - Number is listed above raised Holley on top of TBI unit.

Injectors are 5276, I am able to x-ref the injectors and that is all...

Thanks

 

i would email holley on that. they were always good getting back to me.

 

Did that too, was hoping to tackle this one from both sides..

Thanks
