Can you guys tell me if headers off an 88 F350 efi 460/auto fit my 86 F350 460 auto w/ carb??? They have different part numbers (Hedman 89340 vs 89460), but I think that is for an EGR fitting that I would plug on the '86. Are the heads and the chassis alignments the same? Everything but the year model on the trucks are the same.
[updated:LAST EDITED ON 31-Oct-02 AT 10:16 PM (EST)]is that the only difference? Some manufactures don't offer an application for my 86 F350 460cid, but they do for the 73-79. Aside from emmissions (my 86 has no connections to the exhaust) will these interchange?
In short, could a set of dynomax for a '79 F350 w/460 fit on my '86 F350 w/460 with no modifications? Or could a set for a '87 fit my '86 if I plugged the holes?
Are the chassis setups that different? Will EFI headers fit a carb'd engine? Will 4X4 headers fit a 4X2?
