Way back a 100 years ago (or so it seems) I put a 4bbl on my new 76 Monza / 262 V8, 4sp (after the 1 year warranty was out of course). I used a Holley Street Dominator and a Holley 450 4bbl. Using the then in vogue Moroso gold anodized air cleaner I had no problems with hood clearance. When I put in a Comp Cams cam and kit, a set of headers and dual exhausts it was a pretty peppy setup. Of course it paled in comparison with the LT1 350 that followed it. Needless to say the rear end did not like it though.
