I do not have any information on the numbers but I can suggest you to www.motorchrome.com for the intake, they sell chrome intakes there but, there not true edlebrock intakes, there edlebrock style so they say preformer, torker and things like that in the descriptions for the part, the good thing about this is there about 100 bucks cheaper. Ex. $229 edle preformer polished intake from jegs, $149 preformer style polished intake from motorchrome. I hope this helps.
