I have a 4 barrel intake for a 273 for sale it takes a standard afb carb I'll take 50 bucks for it. they will fit on all 273s. I also have a solid lifter cam and lifters for the same engine also the push rods. I have a rebuildable 273 block I would like to sell. As a matter of fact, I have the whole engine including pistons. the crank is kaput due to a spun rod. the pistons are usable but number one rod is no good for the same reason. get in touch with me and we can discuss it.
