348 409 info

At the present time I am working on the production of cast alloy oil pans for these W motors. My 63 425hp 409 is where it belongs in the `63 Biscayne 2 door sedan, (now sold) It saw its first 5000 mile in the `62 Bubble top (sold). The ’58 280HP Tri Power 348 (rebuilt 15000 mile ago) saw its first 7000 miles in the `59 Apache, then 5000 miles in the Bubble top. It is now in the ’61 Parkwood. I have sold the `60 Elcamino, factory 250hp 348 stick, it was a lot of fun, as was the Biscayne. 

348 409 INTERCHANGEABLE PARTS; There are several parts used in the 348 and 409 motors which are common to either the 283 – 350 small blocks and the 396  427  454 mark iv big block.

• The bellhousing bolt pattern is the common SB – BB pattern.
• The motor mounts are standard SB, but I suggest you use the locking type – cheap insurance!
• Fuel pump is small block.
• Hyd lifters are SB.
• Oil pump to dizzy drive shaft is BB, use only steel retainer.
• Overall dimensions are not much more than a SB and weight is less than a BB.

The 348 – 409 will bolt into the same spot a SB was and if the SB had the standard 1962 283 type 2″ Rams Horn exhaust manifolds, I believe the standard 348 2” manifolds will connect to these SB engine pipes.
