As most Performer intake owers know, the upper always cracks or breaks where the bolthole ear is(the front and back on). Mine has broken twice now. When I bought the intake it(the front one) was already broke and I got it welded back on. The guy that did the work welded the back one too because it was cracking. Well shortly after I built my motor I noticed the front cracked again. When I took it off to readjust my rockers and fix the vaccum leak it brok off again and fixed it with good-ole JB Weld. Its holding up fine right now but I adjusted my rockers too loose so I know when I take it off again its gonna break again. So, I'm thinking about getting a Typhoon upper. But if the upper won't bolt right up then I'll just give the Typoon upper and lower a try. I saw it on ebay for like $300. So, what do yall think I should do?
