What's wrong with my motor?
I did the exact same thing as you, OP. I drove my car and knew it was way down on power. Ended up snapping off and intake valve and destroying a piston, bent some rods, scored the cylinder wall, tore up my new edelbrock heads, etc. I had built the engine myself and it ran great, went 12.80's in the 1/4 with iron heads. I swapped to edelbrock's and a bigger cam and totally screwed up the timing.
