Purchased this intake off of eBay a couple years ago- I was sold it under the heading for gmc 270/302. The port spacing is 8.5” which I’m informed is stovebolt spacing. Haven’t seen another to compare. I am in the UK and ship my products worldwide all the time, so worldwide shipping isn’t an issue at all. Please look at the photos and get in touch if there’s anything else you need to know. photos of it on my 302, which is also for sale. carbs will need rebuild or replacing I have photos of the measurements of the port spacing, if your interested drop me a DM thanks Joe 695.00$
