I forgot the size of the lt1 intake manifold inlet. I have to buy a coupler for it and i figure some one knew of the top of there head.

I used a stretched-out 3" Fernco sewer pipe adapter. Looks like it won't fit, but dunk it in boiling water and it'll fit.

A 4" silicon coupler is just slightly loose on my AS&M monoblade. I'd probably stretch a 3.5" to fit if I wanted it to stay on with boost.

i have some 3.5" couplers and it will not fit over mt tpis 58mm throttle body i think i have to go 3.75 or 4. i also have some t bolt clamps. so i can get them air tight if it is a little loose.

The size needed at the TB is 4".
I took a string wrapped it around the TB and cut the string to where it wrapped around the TB touching end to end and measured a length of 12.5" when divided by 3.14(or pie)lol, it comes out to like 3.98"
Long story short, its 4"..
I just ordered some goodies frOm

Yeah, if you have a throttle body with the "lip" at the front (I'm starting to think mine is the only POS that doesn't have this), I think a 4" with a t-bolt on it will work fine.

I believe 3 inches is the length that's needed. Does anyone know the size that's needed to connect the elbow to the mass airflow?
