58 348 Tri-power

[Al T]

I've got a '58 Impala that has a 348 tri-power in it. It's a Canadian built car but I haven't been able to order the GM Heritage package yet. I noticed in a thread on a'61 Bubbletop mention of a vacuum tank for a tri-power application.

My'58 has a vacuum tank installed also. Would this be an indicaiton of an original tri-power car?



Thanks in advance.

Tripower or power brakes.

348 3x2 ("tri power") and/or power brakes. Take note that for '58, the vacuum system for the 348 3x2 utilized a vacuum pump run by the fuel pump. Later '58 used a vacuum tank in place of the vacuum pump.
