I want to get the MSD 8.5mm Super Conductors for my '89 Formula 305 TPI. For those of you with these wires...did you get a custom length, or did you get the universal and cut them yourself? I don't want to mess with cutting them myself if I don't have to, but I haven't found a set specific to third gens. But I did see a set at Jeg's for "SB Chevy '88-up cars". Does this sound like the right set to get?
I also plan on getting the NGK plugs...any ideas on which ones or where to get them?

Thanks in advance!

When I had my stock exhaust manifolds, I needed the mixed set specifically for SBC 3rd Gen F-bodies. When I installed my headers, I had to switch to the "all 90* boots" for SBC.

 

I've got some NGK's from O'Reily's and I'm really satisfied with them, They were cheap (around $1.19 a plug) and give good performance too, IMO. When I got my Accel SuperCoil recently I re-gapped my NGK's to 45 and REALLY noticed a power difference....

NGKs are excellent plugs. I recommend running one level colder than stock since you have an aftermarket ignition. Just to be safe. Look at your spark plugs. If its melted you need a colder plug. If its tan everythings ok. If its grey you need a hotter plug.

I just ordered the MSD wires. The custom ones will fit, Im installing SLP headers and I didnt buy the custom wires because Im not using a wireloom.
