For your info I tried a old 2 / 1 barrell intake on my 235 and had altogether way to much trouble with it, so I went w/ a Clfford water heated intake , works great . I used a edlbrock 500 cfm, the 2 best things I 've bought for it so far. You can put 2 or 4 barrel on them, and they have intakes for 2 carbs. Go to ;www.cliffordperformance.com
