What plugs should I put in?

K, just got my car back from the shop, (electrical issue)

i got a 94 Camaro Z28 w/ vortech supercharger, msd 6btm box

I did the plugs on it. I wanna add i did all 8 on a LT1 in less than an hour. I love Mac headers they worked out perfectly for me.

NOW
The plugs that were in there were Bosch copper plugs, cheap **** .99 each

The plugs i just put in are the NGK TR55's gapped at .050, it didnt run too good with these, initially it started right up like immediatly, but im still getting misfiring like a fouled plug and it got progressively worse.

I want to go with the TR6's i think, they are made for blower applications

So are these the plugs I am going with....or suggest other?
Also wut do i gap them at?

 

try gapping them at .030

 

Yea, that gap is too big, take them down, .30, .35 something around there.. TR55's are ok, so are TR6's .. Autolite 104s work well also.

 

Autolite copper 104's (one range cooler than stock) are probably the best and very cheap. Gap them at .035 ...mine are gapped at .045 right now since I have an MSD but I'm getting a cold miss, not sure if the slightly big gap has something to do with it. I always gapped them at .035 before with no problems so I'm going back to that.

The thing about Autolites is they keep their gap well, whereas TR6's and many others will open up over time ...say you set the gap at .035 at install, you take them out later and somehow they've opened up on their own to .045. The Autolites in my experience do not do this, plus they don't have those ghey screw on ends that come loose
