Thread: Hi-Ram Top 300-232

    Default Hi-Ram Top 300-232

    Hi all, I recently purchased a Holley 2x4 adapter (300-231) for my dual-quad intake. I went to purchase a 105MM top (300-232) only to discover that it’s discontinued. This was a “bolt from the bottom” design, meaning the top section is threaded vs the lower. I see there are tops available that “bolt down from the top”, but I don’t understand how they’re bolting down because the bottom is still not tapped for threads. Are these newer tops compatible with my lower adapter piece? How are they secured? Thanks!

    UPDATE: Talked to Justin at Holley. He did some research, and it appears I was shipped an older model. They shipped my a replacement via Next Day on their dime. Talk about customer service!!!
