1990 Lingenfelter JL1

Hello, I have a question about my corvette. I bought a 1990 corvette coupe that was modified with lingenfelter parts. The engine is the L98 and the corvette has "JL1" badges all over it however I heard the JL1 was the super ram air intake package for the LT5? I have a LPE plate that came with the car that says 435hp so thats all I really know. I have been to lingenfelters website and cannot find any engine package listed. I recently had a mechanic tell me what parts were modified on my vette and he responded with: Open design air intake with K&N element, larger custom made throttle body, custom upper intake and runners, larger fuel injectors, cylinder heads and valvetrain, custom lift camshaft, long tube headers with cora exhaust and high stall torque converter. It has the lingenfelter performance engineering stickers, JL1 decals, and the throttle body is custom engraved with LPE. If ANYBODY knows what package this is that would be awesome. I have tried to get a hold of lingenfelter and they never answer their phones or call you back. my email is patrickmcfadden13 at gmail.com and # is 610-850-4161
