Hello.
Is there a knowledgeable forum user (or just someone with a spare parts manual!) who can identify V8 exhaust manifolds by the casting numbers? I want to know if the number 502834-211540 identifies a pair of manifolds as being the 'S' type or from an automatic V8. Please don't hesitate to post a reply if you can help.
Will the rest of the exhaust system on my automatic mate up to a pair of 'S' manifolds, or would I need different downpipes?
 
hi mr task,
measure the diameter, 3500's should be 62mm 3500 auto are 47mm. an auto exhaust won't mount up to an 's' manifold due to the size difference.
