what dizzy to use?

I purchased one of those $67.00 dollar specials inc delivery HEI dizzys from ebay and had it recurved and it hasn't missed a beat. Ive done close to 6,000 km since the engine rebuild and its been flawless,Like mentioned in one of the posts you need to replace the coil. I run a Bosch 55000 v coil which i purchased from the same vendor.Just to add ive spun this teen engine to 6300-6500 on a few occasions but mainly 5800 with out any ignition related issues. Sorry coil was a extra $35.00
