I had my 1987 350 engine from my IROC rebuilt this summer. I had them put a Custom Cams camshaft into it. I think the model number is vb5775-08 or it could be 08-300-8. Since I got it back it stalls on a cold start almost every time. they said i need to install a performace chip. Any opions? does that sound right? What chip would work if i do need one?

Thanks!
