LS1 in C4?
Has anyone out there done this swap? An LS1 into a C4. There are a lot of these available at very reasonable prices and it sure beats the cost of building up my L98. This would be going into an 89 Auto coupe, but might soon put in a 6spd. I already have a Dana44 with 3.45 gears, and a rebuilt 700R4 with a Protorque 2500 lock up stall converter.
Some questions: 1. will it fit 2. what about accessories 3. what about wiring and ECU 4. transmission/bellhousing fitment issues 5. header and exhaust clearance problems 6. proper radiator 7. smog equipment(making it totally smog legal) And anything else that I missed.
Any help would be greatly appreciated

Re: LS1 in C4? (Mr Mojo)
If it would fit pysically in all other respects the oil pan would likely have to be a custom job. Not a big deal but not cheap. You would have to bring the whole electronics package over to the c4 (i.e. sensors and ECM). I guess you'd likely lose most of your digidash gauges but I'm not sure there. It sure wouldn't be esier than say... just installing a stroker :)

Re: LS1 in C4? (89BP)
Some guy here had one he was doing on a 84. Had a webpage put up. I remember the oil pan issue, just swapped it out or did some welding. The engine sits differently in the bay, it's a bit higher, so you'll need to get a highrise hood to accomodate the front of the engine.
