The 350hp/327 used the -151 cam, (222 duration at .050" and .447" lift). It also had a 585cfm Holley w/ a factory high rise on it, the big fuelie style heads and the 11 to 1 CR. I think the exhaust was 2.5" manifolds, I know the rams-horns in the Duece were this big but don't know about the Chevelle log type?. It came stock w/ a 12 bolt and 3.73".
I knew a guy that had a '66 Duece coupe w/ this setup and a four speed. I used to love to watch the little bugger run through the gears at about a city block to a block and a half away b/c it just used ta raise up at each shift and take off like a rocket. Man, did it run!!! Thats what I wanted but was too late in'66 for me to order one and I didn't know that the '67 325hp/327 engine was the same engine but w/ a Q-Jet and cast-iron intake or I would have one now instead of my SS/RS. My Mom cried when she saw my "radically looking" Camaro the night we picked it up in Dec. '66.
We came outta the service area back to the showroom and she said that she thought I was buying the '67, 275hp/327 Blue Duece coupe setting there in front of us! I told her no b/c I couldn't get the L-79 engine in the '67 Duece. The rest is history. pdq67
