Do any veichles come with the LS1, LS2 or LS7 engines equipped with the FlexFuel package for E85? If so, what would the logistics be for swapping one into a 98+ F-body? Eventually, I'd like to get a 98+ Firebird, and would like to make it capable of running on E85, ideally using stock components (ECM/TCM, Fuel system & sensors) to allow straight E85, straight gasoline (well, 10% Ethenol), or any mix of the two.
On the subject of the 5.7L LS1/6.0L LS2, How do they compare in size physically and power output to the Ford 4.6 SOHC? Long ago, I had thought about dropping a Northstar V8 into my 95 Cougar, but ended up going with the newer 4.6L with the PI heads which woke it up nice. I'd guess it's got 230-250 at the crank. If I wanted to put a 5.7 or 6.0 in, what would be my biggest hurtle? All of the computer systems (air bag, variable steering assist, Cluster {which is super simple; no computer at all}) are independant as near as I can tell. Obviously I'd need complete harnesses, engine, transmission, PCM or ECM & TCM (LS1 or E40 & T42 I'd guess), custom driveshaft... Just thinking out loud here... I like my Cougar and have no desire to get rid of it, but would like to be able to tune it and have more power out of it.
