I just bought a '69 buick with a 350 2bbl. I'm thinking of changing to a 4bbl. I have a stock intake and q-jet to fit. Question 1: is the cam for a 2bbl the same as the 4bbl cam. Question 2: If the cams are different will I gain any performance with the carb and intake swap? Thanks, Brandon
the cams i believe are the same.. you will see a HUGE diffrence in performance with a 4bbl. mostly around 40 mph and up. it puts a new meaning to passing gear if your used to the 2bbl. I did the swap on my 70 350 skylark. wow..... whole new eyeopener. nate
Yep, just wait till you snap them 4 bb open n hit passing gear. The extra gas station visits will be well worth it. Matt uzzled:
hey bradon. i have a stock 4 barrel intake if youre interested. its off my 72 lark. think itll bolt right on?!?!? (someone correct me if im wrong) just make an offer and pay for shipping and its yours. pete
Thanks for the info guys! Pete, I thought I had an old 71 350 intake sitting around, but I can't find it anywhere. Let me know what you want for your intake, how much you think it weights, and your zip code and I'll try to find a shipping price. Also, does the '72 intake have the provisions for an EGR valve? Thanks, Brandon
hey again... i think the intake has the egr valve thingy. ill try and get a pic of it. i know that 72's started getting some smog stuff and 73's really got hit hard. find out on shipping and then ya can make an offer. i imagine its 50 to 60 pounds. pete pete_119@yahoo.com 619-944-5226
If you are planning to bye a new camshaft, learn from my mistake. Give TA Performance, Tri Shield Performance or Poston a call. They can tell you what is best suited for your combo. The comp. ratio is different between 2-bbl and 4-bbl stock 350: s and this among other things will make a difference when picking the right hp- cam shaft Lars
