HO intake questions

[ltdcrwnvic]

how do i know whether a intake, bottom and upper, are HO? are they marked with a HO sumwhere in particular? or do i look for sumthing different? some sort of code or engravings?
im asking b/c my friend is selling me his upper and lower intake off his '91 mustang lx. you guys think or know if its a HO? he's saying it is but the only proof he has is da lil plate ontop of da upper intake dat says "5.0 ford HO." so wat do you guys think?

Lower intakes are the same for HO and non-Ho motors, but get his and get it ported while driving your current one, then just swap it in together with the upper. Now the upper intakes are different, remove that fancy plate that says "5.0 HO" and look on the main runner, it should have "HO" stamped on it somewhere on top, near the end where the EGR spacer and the TB go.

kew kew, ill go check it out later today. da TB is gonna be included in this purchase. do you by any chance know da MM of this stock TB on da intake IF its a HO? dont really know if i should just port it or if its big enough then ill just leave it alone. and porting da lower intake, what do you guys recommend me porting it to?

Stock non-HO throttle body and EGR spacer are 50mm in diameter, stock HO parts are 60mm. You can use the HO-parts in your car if you find some long-ass cables for them (Mark VII ones work OK, but ideally you want something even longer), or fuck around with boring out the non-HO parts. About the lower intake, look at the runners, you mostly want to straighthen their bends as much as possible, there are two or three that are particularly bad.

I'd have the stock EGR spacer bored out. turbo2256b is selling bored stock EGR spacers in the classified section I think. The throttle lever needs to be swapped between the non-HO throttle body and the HO body, but thats not a big deal. Just need access to a die grinder and you'll need someone to tack weld the throttle lever on. The Mark VII cable swap thing works I guess but personally I think it looks really messy and I also dont like the looks of the cable geometry. They look like the bends are too tight for proper cable life / action. The stock cable routing with the properly modded throttle body and spacer work perfectly.
