Spark Plugs ?

[ikle]

I am thinking of using AC-r43ts spark plugs gaped at 32 would this be the correct spark plugs with the correct gap for my combo?Also what happens when you run a tighter or bigger gap,does one burn more of the fuel better?Trying to figure out these cars,any info would be great.Thanks,ikle.

You should be ok with your combo. A larger gap will help ignite the air/fuel mixture, but the larger the gap, the easier the spark is blown out by high boost pressures. If you run a tighter gap, the AF mixture may not ignite. What boost are you running?

Here's a link to most everything you'll need to know about turbo Buicks. Lots of good info on these.....spend a few months reading them.

I am running 15# of boost right now, but after I get a handle on my high BLM's(144) I will be running 17# of boost with a Poston street chip.
