    Not perfect but close.

    Lengths aren't perfect but they are pretty close. Ran mine around the front side of the valve covers. Work really well and seem to perform better than the 9mm I had on there did. 351W - 1992 Bronco EFI, mildly built. Alum heads, oversized SS valves, roller rockers, SS headers.

    Excellent except for one wire .

    The only problem is with # 2 wire . If you are using a GM HEI distributor, you have to wrap this wire around the large cap making it too short . You can't go between the other wires like other dist because the Gm one has the Large coil in cap . It's too bad the HEI wire package would have an extra long #2 wire . Luckily, I had a fairly new set for another project with longer wires . Only problem was, the loner wire was yellow !

    Good quality. Nice fit.

    Nice quality wires that fit BBC under headers. Installed on race car so header clearance was not a problem. Pre made wires fit surprisingly well and I would buy again.
