==Clearance issues== In cars the clearance problems are usually at the front crossmember, the driver side exhaust manifold, and possibly the HVAC airbox on the firewall. This can be modified with fiberglass or sheetmetal if necessary. Streetrods usually have sufficient room to drop the big Cad engine in. The fit is tight like with a big block Chevy, but the only change usually required will be in motor mount placement. Most all vehicles requiring a rear-sump oil pan and pickup can use the Eldorado pan and pickup tube, or a mid-sump pan and pickup as found on the smaller 368-425 Cadillac engines of 1977-'79 vintage. Stock exhaust manifolds may be used, or aftermarket block-hugger style headers can be sourced from Sanderson. In most cases where a big block Chevy header can be used, the Chevy flanges can be removed and Cad flanges can be made up quite easily. The primary tubes may need a bit of tweaking to line up with the ports with this method. Remember that the front and rear drive exhaust manifolds are different for the driver side. This may help in routing the exhaust if it is a tight fit on that side. The Cad engines do not fit easily in some GM chassis. Never fit the engine in without putting the exhaust manifold on first. Better yet, use a custom set of block hugger headers, as Cad parts are usually insanely expensive (but worth it in this case).
