Sounds like an LT5 too me, shares basically nothing with these motors and is NOT worthwhile. Only think it has going for it is the WOW factor was like a $25K option on the Vette in the late 80s early 90s, believe the max rating was 410hp.

I don't think there's any way to incorporate LT5 heads into an LT1/4 motor. I've seen 350's with DOHC back when I was in highschool. My shop teacher was old school and had pics of so many sweet things.

Hell, maybe he just has a Northstar motor lol

Have you looked under many LT1's lately? These came from the factory with standard oil leakage. We had a 10K mile 96 SS in the show room...leaked oil. They're just too powerful to keep it in
