Engine is toast.....
Honestly, if you really like the car, put in a roller SBC 4 bolt main truck block, like my car with a '89 block.....put on the L98 #113 heads and dress up the top the way you like.....
I updated my engine back in '97-98 but learned the hard way, stick with a stock GM cam.....
Forget that aftermarket shit, especially anything from TPIS in Chaska Minn.....they are a crooked outfit, and sold me a defective ZZ9 cam I suffered with for damn nearly EVER.....long story....
just some advice....
