The stock clutch should be fine for 273 horse power.
I ran the stock clutch in my 94 12 valve for years and my truck was dynoed multiple times at 398 horse power. If anything look at a South Bend Con OFE. I ended up with one for free and threw it in my lil 12 valve and that is a sweet clutch. Drives just like the factory one and is rated for 400+ horse power
