Hi folks, I am installing a new TA 4 barrel intake in my 72 Skylark Custom with a 350 that has a 3 on the tree manual tranny. There is a threaded hole for a vacuum line on the rear of the intake. Can I just plug that up and just not use it? if so what should I use? thanks.
Sure, just plug it up. I believe it is a 1/8 NPT plug. http://www.discounthydraulichose.com/33152_Brass_NPTF_Hex_head_Plug_p/33152.htm You should be able to find that at a plumbing supply or parts store.
