Ok I installed a new 88 and a half engine in my 86 sammy. I had to swap carbs otherwise everthing was normal. Hooked er all up, she fired up nice, Idols a little high, prob needs a little timing adjustment. Sept it hella lacks power, Like my old engine was shot and was a sports car compared to this? whats the deal. I drove er about 4 kms, see if it would clean up, The Exaust manifold was glowing red, so hot, not good, Any Ideas what i gotta fix?
