Oil/Filters I am running a Wix brand remote oil filter kit that just spins onto the Buick 231 V6 oil pump base. I mounted the filter in the passenger side inner wheel well. I is out of the way and easy to access. I added the oil cooler to help cool the engine. The oil cooler dropped the engine temp by 20 degrees Fahrenheit.

Plenum Modifications I decided to modify the plenum cover and ram pipe manifold after starting to make a bulged hood. After starting on the hood I decided it would be easier to cut the plenum down and keep the original MGB hood. I found that I needed 1 3/4" to clear the hood, so I cut 2" out of the plenum, and ram pipe manifold. The pictures show what I did pretty clearly. I have not seen this done in such a way before, but It should work well. I cut a new lid out of a 1/4" piece of aluminum and had it welded to the plenum. I also had to shorten the ram pipes to clear the new lowered plenum. I milled 11/16" out of the bottom of the ram pipe housing. I also had to machine the flange where the vacuum lines attach buy 1/4". I relocated the vacuums using new nipples. I milled 1 1/8" out of the top of the plenum. With all this modifying I was able to fit the fuel injection under the Original hood with a quarter inch to spare.
Before modifying the Ram pipes After machining 1 3/8" off the ram pipes and 3/4" off the intake base
