LT1 / LS1 in '97 Formula

Dec 29, 2003 4 Replies

I've got a '97 Formula with an LT1 in it. When my wife's car get's paid-off, I would love to put an SLP Stroker Engine package in my Formula ( see link

This package includes the '97 model year, but it's based on the LS1 engine and I have the LT1. Did some '97s come with the LS1? If so, what would keep me from replacing my LT1 with an LS1 (with the Stroker package)?



When I asked SLP about this the short reply was that they didn't have a stroker package for the LT1, but that wasn't my question...



I've looked at the LT1 to LT4 conversion option, which is obviously a LOT cheaper. Are there any other big HP options that I should consider?



Thanks! SR-71 (Blackbird) '97 Firebird Formula

The LS1 was in the vette in 97, probably what they were refering to, As far I I know They didn tput any LS1s in Production 97 F-bodies,

You'd need to put new motor mounts in to fit the LS1 block into an LT1 car, but then again, if you could afford the ridiculously absurd price of $12 grand for a new motor, I'm sure you could afford the cost of welding new mounts!
