?501 headers on a 350 (early models)

FE350CS · May 29th, 2018, 02:16 PM

Has anyone had experience with putting 501 headers on a 350? (early model engine, mine 92) Did the power delivery broaden or shift?

I purchased a later model 501 FC pipe to replace my FE long one and it included the headers, measuring ID/OD they are 15% larger. Would take a bit of heat + gentle persuasion to fit them so wanted to see if it's worth the effort?

Thanks in advance.

Hej.
I have 501 headers on a 400 and can`t notice any problems with that.

I put the 470 headers on my 400 and got another 1bhp throughout the revs. I have brand new chromed stainless steel 501 headers for sale.
