Any suggestions on a cam upgrade for a completely stock 1988 IROC with a 305 TPI? Looking for a slightly rough idle.

i wonder how a HOT cam kit would work in an otherwise stock TPI motor?
probably not too well without other upgrades, since the TPI runs setup runs out of steam right when the HOT cam starts to shine..

I got a lot of good responses when I asked about this cam in my stock 305. It's the "upgrade" cam or "RV", says performance on the box . So I installed it. This 305 still sucks! Slow as a turtle.

Looking for a slightly rough idle.

If you want a rough idle, take a spark plug wire off

That's the good old Performer 204/214 cam that you can buy from Summit w/ lifters for less than a "C"-note..

And please consider these too.

i'm pretty sure an 88 with TPI will have a roller cam in it.

I honestly have NO idea is the ONLY reason I went w/ the old style cams!!

I spent some time lurking around over at www.thirdgen.org to learn more about the Fuel injected motors. It probably won't have a rough idle but, the 305 TPI engines respond well to the stock GM LT1 roller cams that were installed in mid '90's model Corvettes. Provided you get the proper EPROM chip to support the cam.
