Hi Everybdy, I need comment from knowledgeable members on this issue pls.. VIN of my Mach1 convert is 1F03F172881,,,,casting no. of the engine behind the starter motor is D2AE-CA , casting date just below this casting no. is 3A15. What do you guys interpret from these actual data ?
My understanding was I had a 1971 convert with a 302.
Now seems like the engine is a 351 but the year of casting 72 and date of casting 73 from the research done on net. Below is one posting I found on net.. Your learned opinion is highly appreciated to resolve this issue. Thanx all the same, in advance.
(PS: I believe I have read these no.s on block correctly, after taking several photos of them )
================
D = the decade made "70's"
2 = year produced
A = Ford or the Z= mustang
E = engine part
now after the dash is what makes a 2 bolt or 4 bolt main, since the 351c was only around for 4 years it makes it easy to read the codes:
-D = 2 BOLT MAIN
-C = 4 BOLT MAIN
-A = 4 BOLT MAIN
These codes tell you what you have so you don't have to drop the pan just to determine whether or not you have a 2 or 4 bolt main,I hope this helps you.
IT LOOKS LIKE YOU HAVE A 4 BOLT MAIN.
