So I'm gonna put the big block back in my truck, the 350 runs great but I guess I was spoiled with the big block first and can't beat that torque. Anyway I have searched all over and I want to get a clear answer from someone who has done this. What do I need to do to get headers fit in my 74 4x4 with the 454. Get the motor mounts for the Bhutan that bolt to the motor but can't find ones for the frame that r bb specific? Also what brand header have u guys used for this? Thanks.
