Engine- Try to get a complete engine for all of the accessories especially brackets. An engine tin can run from $50 to still much y'all want to spend. A complete new performance motor will run $2000+. Sometimes a new engine can exist cheaper than a rebuild plus you lot get a warranty.

Oil pan modification or the apply of a 4×4 pan is required on near Jeep installations. Exhaust manifold changes add to the cost of the bandy. Parts interchangeability is not nearly as good every bit on Chevy V8.
