Hi!

Ive installad an MSD 8366 Distributor & MSD Blastercoil (48.000V) and MSD 8.5mm Super conductor wires. and Brand new AC Delco RJ45TS sparkplugs.

What gap shall I have on that ? right now im running in stock gap = 035"

I heard like 045" would be good ? shall I run with that or do you guys have any other recommentaions ?

And Sparkplug, I can use the RJ45TS (stock plugs) or shall I have any others ? and IF so, please give me some info about them.. There is no danger of running on the Delco ones ?! or ?!

 

The wider the gap the higher the volts to jump across.
Old carb type coils 30-50,000 volts .035
HEI 70,000 volts .045-.060
New coil packs can kill you .080

anything from .040 to .060 or so.

BTW lawn mowers .025

GM runs Delco all the time. It is OEM stock.

The R in the part number, means it is a resister plug and it takes more volts to fire.

 

So if I use 045" on my RJ45TS sparkplugs will do fine then ?
No need to change to another sparkplug ?
