Re: Marine L-88 Engine w/ Cast Iron Heads
Here is the engine as it was pulled. The carb is a 3246 service dated Holley. I have seen 3246 carbs on most marine 427s. The pulleys are GM units but are not deep groove.

Re: Marine L-88 Engine w/ Cast Iron Heads
The front pad is stamped TO3177BL. The 7BL suffix must mean closed chamber L-88 with cast iron heads.
 The 3933198 intake is dated 9.18.68. I believe the 198 intakes were only made in certain runs. I don't think I have ever seen a casting date from October 68-Feb 69 unless the 198 was hand stamped.
