1989 f150 intake plenium
 

does anyone know the size of the torrex bolt on the intake plenium on a 1989 f150 302.

Welcome to the forum

I'm thinking T-25 but it's been awhile.

Off the top of my head, I remember it being a T-40

100% sure its a T30, or at least it was on my 91 5.0 and my 89 5.8

I just checked and it's a T-40 on both my '87 302 and '95 351. I found another thread where others said it was a T-45, but I couldn't get a T-45 to fit in either engine. A T-30 also fit, but was loose.
