Holley Throttle Body Owners Inside
I bought a Holley 52mm throttle body and found that the stock ducting is too small to fit. I've loosened the clamp as far as it will go and it still won't fit. I measured the outer diameters and the Holley throttle body is larger. What did anyone else do? Was this a screw up on Holley's part?

Mine goes on, but it's a tight fit. You just have to start it on the bottom and work it onto the top.

Thanks for the info. I thought maybe it was just me missing something obvious. I wrapped a piece of tape around the Holley throttle body to measure circumference (I know it's not a circle, but I couldn't think of a better word) and found it to be about 3/8 inch larger than the stock unit. What I'm still wondering, though, is why Holley made their unit that much larger. I realize the bores are larger, but I still they could've done better. It seems like there is more than enough metal where the throttle body attaches to the ducting. Oh well, what do I know? I'm just a consumer, not an engineer.

The LT1 elbow just bolted right up? It looks like it's slightly smaller.

What do you mean bolted right up? It doesnt bolt to anything. Its an elbow. There are two sleeves that go on each end and one clamps to the tb. It works fine
