I am doing my cam install and was wondering what the benefit of better spark plugs would be?

I'd like to see some imput on this myself, I changed out my plugs with some of the stock delco ones a year or so again, but am about to do a cam install..

The benefit of double platinum plugs is that they last longer. None perform better than the other recomended plug. You can pick up a few HP with synthetic oil and syn.tranny fluid

I think it is more of a benefit of having the right plug, not a better plug. If you are talking about making more power. Just get the right heat range, gap correctly and it'll be ok. If running stock compression, stock plugs should work fine. Or an equal.

Right on the money.

Stock compression = NGK TR55's
If you're running higher compression or nitrous, then go with TR6's.

Stock is around .045 I believe for TR55's.
