Every swap has it's ups and downs. What will fit and what won't.
The vacuum brake booster on this was the first thing to go. Next up was to see what could fit in it's place. BMW Hydroboost is very bulky but the GM Hydroboost fit nicely once we pushed it off center.
Once we got the engine where it was the most happy we fabricated some engine mounts. This car retained stock rubber mounts under the metal arm to help remove vibrations.
Well at least a hydro boost will fit
Manifold on passenger side is no issue
Drivers side will require custom manifold
Passenger side engine mount in progress
Drivers side mount tacked together
