'74 hei - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, as I mull over, (still), the switching from points to an HEI, ..I discovered that GM first used an HEI in the '74 SBC. I'm wondering if anyone out there has installed one of these in their '71 or '72 C10 SBC. (I'm still running all OEM). If you did, was this just a plug 'n play with the exception of getting a switched 12vdc power supply which I have procured from the guys at YearOne, (and it's PINK!). Or do I still need to "tweak" the weights and springs, etc.? I also think this may look the most "stock" with the exception of going the Pertronix route, which I'm sorta leaning away from.

Thanks for any advice.
