I was wonderin if the parts from a 94 and up 3.8 mustang would  bolt up to my 1990 thunderbird cuz the engine looks the same?

I also need some tips on some cheap hp upgrades, i already have a custom ram air and was thinking about underdrive pulley's but want to add more.

hi my name is sebastian and i have a v6 myself  if your v6 thunderbird is not supercharged then everything and anything you have on the 1994 mustang motor will fit 100% if your thunderbird is a sc(supercharged)then things are styll the same but internals are different, the block has a sc stamp on it it consists of taller mains and forged pistons a very very nice crank i think it`s steel and the heads are pretty muchthe same but they have a sc stamp on the corner of them and the water jackets are a little bit different but as for the valve sizes they are the same too. now the lower intake is completely different because it fits a sc  i have a 1998 v6 stang my self and i have purchased a 4.2 stroker kit from morana in case you don`t knoiw who morana is he is  like the ford guru he`s the master of any ford motor and has been for like 30 years he has recenlty been building a twin turbo v6 it`s a 81 if your interested in any of this v6 stuff and if you wanna get involved with it check out his site it`s kindof a temporaray site for now because he has just moved locations and he is just concentrating on the 2.5dohc,2.9,3.0dohc,3.0vulcan,3.8n/a,3.8sc,and the 4.0v6`s check out his site and give him a call you could learn alot of intersting things from the guy www.moranav6racing.com good luck with your car(s)  

i need a enlarged picture of the 88 tbirds 3.8 v6 do you have any heads up for me?
