1990 camaro tpi plugs help needed
 

quick question and i dont want to sound stupid lol..... i got a 90 iroc 5.0 305 tpi motor.... is there a difference if i use plugs for the same year but for the 350.... i got bosch platinum 4's and denso iridium (12 bucks each) plugs for the 1990 350 tpi can i use the iridums in my 305? yes? no? i always thought sbc is a sbc and you can use any sbc plug but someone please let me know thanks Jared

Why not just use delco r45ts? Cheaper and won't foul out fast like the +4's do. If you do use those though, they shouldn't really effect anything. I don't know why people spend a million dollars on spark plugs that won't gain them anything on a stock motor...

I've always had luck with $2 NGKs on street cars. None with Boschs.

Yea, you should be fine, but there is also no need to spend that much. AC Delco plugs FTW :)
