Riddle me this

[chevymans409]

I recently finished a build of a 400 sbc for my 68 camaro it has side pipes, when I stand in front of it both sides of the motor are making different lopes / sounds...... Is it normal I have had the car 16 years and the pipes 14 and I don’t ever remember it being so obviously different but this is my most radical build to date.

Could there be something not firing on one side?

lifters out of adjustment? plug bad? wire, cap, carb with dual plane intake??? could be many things could be nothing. I figure your talking idle speed whats it like with a rev?

Ideals at 900 and its snappy / i took it up to the chasi dyno and it made 405 hp to the rear wheels at 5300 RMP and and like 450 LBTQ at 4700 to me this seems really low on the RMP scall i wanted a 7000 rmp motor, My first thought was the lifter but i ajusted them a second time this time hot with no change. Im just stumped.

well you got short rockers and cam advanced 7 *

sounds different because of the firing order

[chevymans409]

i been putting off putting the cam to straight up, you think 1.6 rocker would be better

[jerry clayton]

yep 1.6 plus set the cam straight up or even retard a degree or so if you want to move the curve higher
