Got a friend locally who owns an 87 Caprice with a 305. He is complaining of some pronounced sluggishness and hesitation when driving the car soon after starting it. He claims that after 30 minutes of driving or getting up to highway speeds, the sluggishness goes away, even when accelerating from a dead stop. He took the car to a local carb/fuel injection shop who claimed the issue was due to venting in the fuel system, and even if he performs the eventual install of a crate engine, he will still experience the same sluggishness. I am not a super mechanic anyways, but this seemed dubious to me.

Well, here's the usual "could be many things".

Check EGR operation, make sure fuel pressure is good, check for vacuum leaks, clogged cats, and makecsurecthst the choke works properly AND the secondaries linkage is able to move freely without obstruction.

All of this or change to a different carb and big cap HEI distributor and all of his issues will go away. It'll still be a 305 but it'll have way more umph than before, also don't expect the world from a stock 80s mileage magic gear ratio. Don't forget the basics...could just use a tuneup. I would pull some plugs to check them.

Thanks guys. All of this was based on what he said and what the carb specialist said, which sounded odd. I will let him know. They owner is looking at the 350 HO crate as his new engine. I might also recommend to him getting the car re-geared.

My carb must have had issues (other than being what it was in the first place) because my cat was empty.

If you want to go "performance" get a tru trac with 3.73s and a higher stall converter.
