Not Ranked
If I use a early 68 hyd SO block with out casting #'s. Is it considered a 1960 427?
The casting # for the heads are between the #2 & 3 exhaust ports.
Which Hi Riser intake do you have? There are 2 different 2 x4 and 1 single 4. The casting #'s for the intakes are C4AE-9425-C for the 64 Thunder Bolt, C4AE-9425-D for the 64 Liteweight Galaxie and C4AE-9425-E for the single 4. Not sure what the original application is for the single 4.
