This is not the Q you've asked but -
In my archive I have 5 - 7 methods to f/u w/this 'issue' - one of which will not wrk 4 U (I assUme). The 1st.
Let's C if I can remember them all w/o a painful & difficult search of my system:
* Body lift (more for bmbm40, a vehicle called Buck, myself & others - trucks),
* suspension lift (also prob not 4 U) have helped some (altho I can't C how),
* air cleaner changes (I have a stock 1 that's been a 38 yr search to ID) - it sits dwn beside the valve cover,
* maverick mounts and towers, ('slot' the mount 4 more drop) or 'hard mount' the motor (again I don't recommend),
* an autolite or a carter RBS carb, (&/or mill the head 4 a direct mount 1) or weber/other side draFT (better 4 racers),
* hood scoop
* ?(nope, guess I forgot)?
Who can chip in any others?
