OK..When I get my engine back together I am planning on changing the plus from the AC Delco Platinums I have now to something different. After some searching of ym local auto parts stores here is what my chices are...
Bosch Platinum +4
NGK 3951 V-Power
Champion 3013 Platinum Power
Autolite Double Platinum APP605.

Which of the plugs would be the best, or should I just stay with the AC Delco plugs?

Peronsally I would stay with Delco. Delco has a plug out called Iridium (sp?) now....you might want to check into that.

From your list of 4 I use the autolites, have not had them for that many miles yet but so far so good. They helped with high speed accel from 60-80 mph.

Avoid Bosch alltogether. I see you have plugs and wires by them. Ditch them both if you can. They can't withstand the heat of the 3800 like the other ones. Are the champions the new one they have? I know someone talked about a new champion plug around here, and I saw some at walmart.

NGK makes AC Delco plugs. Stick with either of those. Is the V-power the TR55 or TR6, or something else?

And ditto on the bosch.

Will the NGK PLugs are the TR55... Are those good?

I'm also looking for plug wires... I have 4 to choose from...

MSD Heli Coil 8mm
MSD 8.5 mm Super Conductor
Accel 8mm Super Stock, Graphite, Red
Autolite Profit 86197

Which plug wires woud be the best... They will probably be going with NGK TR55 V-Power Plugs, and evenutally MSD coils.

Taylor Spiro pro are also a nice choice

MSD 8.5 are the best out of your list, and the MSD coils won't get you anything performance wise.

I found some different plugs how about Denso PLatinum Plugs?
I'd like to get the Denso Iridium Plugs, but for 12.99 a piece I cant afford them right now. I'd also like to try the Accel 8176 Premium/Platinum, but they are 13.99. So I can't afford them either.

Would Splitfire Split V design plug be good?

NGK V-power TR55'* are one heat range colder than stock, and will support your planned mods very well. I ran them for a year, but had to move colder to the TR6 recently.

The Taylor and MSD wires are widely regarded as the best. Taylors are cheaper, and available in more colors. www.grandprixstore.com the Grand Prix plug wire set is a perfect fit for us.
