VOLVO 700 SERIES V8 MOTOR MOUNTING KIT
Part # VOL-700. Shipping weight, 22 lbs
The Stealth Conversions Volvo 700 series V8 motor mounting kit consists of aluminum adapter plates that bolt onto the Volvo crossmember, steel engine brackets, Chevrolet style rubber isolators and a transmission crossmember.
The steel engine brackets have slotted mounting holes to allow adjusting the engine position front-to-back and side-to-side.
The aluminum adapter plates bolt to the front crossmember and have two sets of holes to increase the fore/aft range of the engine position, and allow different exhaust manifolds to be used.
The height of the engine can be adjusted by installing shims (or spacers) between the crossmember adapter plates and the Chevrolet mounts (isolators).
The transmission crossmember bolts to the stock Volvo mounting provisions and is designed for the 700-R4 transmission (also called the 4L60 transmission), and the Camaro T5 transmission. An extension plate is available that allows using a Turbo-350 transmission.
The V8 engine/transmission position is dictated by several considerations:
- Crankshaft centerline and driveshaft angles should remain close to stock to avoid drive line vibration.
- Keep body mods and oil pan mods to a minimum.
- On swaps using the Camaro 5-speed or six-speed manual transmission, the shifter position should come out of the stock shifter hole. Trying to modify an interior can be more difficult than the entire engine swap.
In the Volvo 700, the V8 engine position will not vary that much. Due to the location of the frame rails, radiator, firewall, front crossmember, and the transmission tunnel; the forward/rearward position can be adjusted about 2", the height can be adjusted by 1/2" and the side-to-side position can be adjusted by 1".
The more the engine is positioned forward, the less firewall and transmission tunnel modifications are required. However, the more the engine is positioned forward, the more difficult it is to make the cooling system work.
Moving the engine rearward for improved weight distribution is not going to make a very big difference — for every inch the engine/transmission is moved rearward, only about 6 lbs is shifted off the front wheels. Also, excessively hammering the firewall can damage the ventilation components just behind the firewall. The main reason for moving the engine rearward is for the cooling system, and for the shifter position when using a Camaro 5-speed or 6-speed transmission.
The stock Volvo engine/transmission is not centered in the chassis — it is offset to the passenger’s side. The Chevrolet engine is offset towards the passenger side by about 1/2" to 1-1/2" to improve clearance between the exhaust manifold and the steering shaft. Also, the engine/transmission needs to be offset to the passenger’s side for shift linkage clearance.
