This is for a pair of 1970 boss 302 metering blocks. These came straight from Holley in a buyout. Although they are NOS they are not machined yet, not sure if they are worth machining, but they are here if someone needs the, I’m going to guess the 80s or 90s and not from actual 1970, i have a few sets of these so you might not get these exact ones, but the exact same thing. Please let me know if you have any questions Thanks
