Cool dude
Put a Weiand tunnel-ram on my 66 Coronet. Has a 440 i built.
I ran dual 600 Edelbrocks before on a ch28 dual plane manifold. Ran great with the recommended jetting from Edelbrock.
I had to up the secondary jets to the stock size for the 1405's because of a lean spot.
But my question is about timing. It now pings under full throttle and a heavy load.
Could this be caused by there being more cylinder pressure due to the ram effect of the manifold?
I know I can tune it to be right, I installed it 2 days ago.
Just was interesting how things changed. I like to experiment and thats mainly why I installed it. Good learning experience. It performs really well and I can feel the mid range to upper punch with minimal changes in the low end, and it looks bitchin!
