hey guys, relatively new to the boards. but ive got a 76 corona 4 door. with the 20r motor.
the issue im having is that ive got no power and it wont get above 70mph.
what i need to know is do the exhaust manifolds have the little damper things in them that open and close.
when i run it, even for a short period. the manifold gets cherry red hot. which is making me think that im not getting all of my exhaust out.
it pushes air though the muffler. but its not alot.
im just curious if any of your cars do that as well, or if theres something more serious i need to be worrying about.
thanks for any advice in advance guys.
