LT1 / LS1 in '97 Formula

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 first used in the F car in 1998. 1997 was the first year for the LS1, and it debuted in the Corvette.

Same with the L98 (lags behind the F car a year or two). L98 was first used in

1985 in the Corvette and then in 1987 in the F car. LT1 first used in 1992 on the Corvette and then in 1993 on the F car.

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!
