New 440 Build - Ignition Question

Rob - I built a motor almost exactly like yours with the exception I used 906 heads. Motor ran well, dynoed very nicely. In the car I used a MP distributor and orange box and started having problems. Engine would heat, and couple of small other gremlins. Took to the track, first few runs where great. Then noticed detonation issue after one run. From there it was a slippery slope. I ended up popping off #4 top of the piston. Couple of things I learned - First I wish I had CUDA's post back then, I was running 37* and believe timing was my final train wreck.

Now if I have a car that I take to track I use an MSD Box and locked out distributor. Yes smarter people can and have worked through the MP distributors and box's, however I rather have full control.

Also - hypers, I will never use them again for anything that goes to a track. I checked, double checked gap, and everything multiple times, could I have screwed something up - of course.

Between the pistons and timing, they are not forgiving when load is applied multiple times - next thing you know we are off the tracks.

My 2 cents
