I bought a complete 4.1 about 20 years ago to put in my s10, I thought I tossed the Intake but I ended up finding it. So I’m just going to run that for now to save some cash.
Is 291 the casting # of the 4.1 block, or is that something different?
N2buick, I tried searching hi and low for a Weind intake. Is it single plane?
