While my 292 project incubates, I'm planning another six for a Canadian 55 Pontiac, which is all 55 Chevy underneath. I'm looking at a 250 Mercruiser for sale or another 292 to install and I came across a triple Weber sidedraft carb setup off of a 250. The gentlemen stated it was off of a track car but we didn't get into specifics. His setup does not come with an intake. Can they be run bolted to the block on the street using headers or do you need an intake? Am I asking for trouble going down this road? Asking is $1000, Canadian mind you but still is really really steep regardless, in my opinion. The car will be backed by a 700r4, mods to the 250 Mercruiser will be minimal if at all. Diff looks like 3.08 rear gears or maybe 3.25, and will be summer and long distance driven. Thoughts?
