: The 32/36DGAS should be a plug and play carb for your car. However, if you are going to go to the 38DGAS, you must hollow out the the 1 1/2' thick aluminum piece inbetween the two circular intake holes. This is a clearance issue for the baffles that swing open. This process isn't too bad. Just take everything off and catch all the coolant in a drain pan. The worst part is the scrapes on your knuckles from reaching the intake manifold nuts securing the manifold to the block.
: As far as the removing of the aluminium... A SawsAll works best. Be sure to use to use plenty of drill oil to keep the cutting blade cool when removing the chunk of aluminium. It is soooo key to not going through 5 blades and getting a nice cut so you don't have to file for hours.
: Figure 8 hrs. your first time around this job. Twice what it should take if you have done the job before.
I got my trusty dremmel tool out. sat in the sun and in 2 hours opened up the mnifold for 32/36 and did 3 ports as far as the tool will reach. I will open up to 38/38 just in case. if you have seen the trans adapt carb spacer with the angle grove,you can try that too .At least a swirl motion to the carb base and port. This adds tumble do not polish to a mirror. A few hours and free HP
Mainifold on and off is a PAIN but you can do it
