Meh...
LT1's werent ok mills but between The 2 bolt mains they used in the impala versions, the omni spark issues, cooling issues and IMO LOW HP/trq numbers (in the impalas) is what kept me from buying one back in '97

Vettes only made 300hp at that point in 96 when the Impala was in production. Yes, it was 40hp down, but the F-bodies were rated at 275hp for most of their life, and later 285 in 97. Realistically, its a very minor difference. The iron heads on the impala actually flow more, but have lower compression. The cam is slightly different too, but not significantly. Most of the difference is because of the exhaust anyways. More restrictive exhaust systems. Internally the Vette and F-body LT1's were the same. So long as you didn't look at a 4.3L L99 (smaller LT1) which was much worse off with only 200hp and 245lb/ft torque. The LT1's were far better than anything ford had out in a sedan.

I will be going with a LE1 setup which should give me a fun number at the wheels without a major loss in economy, and still allowing me to run a regular 3.23 axel and stock stall.
