70 L34-LS5 Intake Question
What month in 1970 did GM start casting the second design LS5-L34 low-pro Q-jet intakes. I have a 3955287 (2) under the casting number and numbered intake runners (like 1971) and later. My casting date is E-1-70. May 70 castings would certainly still be used in 70 production, wouldn't they? Anybody know of an April 70 casting that is the first design without the numbered ports? MR70 can you answer this question?
