  • Work as it should
All bolts work and nuts work fine like they should. wish the bolts for the spacer could of been Allen heads. But the Phillips head did work

  • Works pretty good.
Definitely had to modify the space to fit but nothing drastic. Works fairly well but I bet a solid phenolic carb spacer would work better then a part aluminum part phenolic spacer does. Why doesn’t any make a qjet intake to a standard 4 bbl carb spacer that’s all phenolic?

worked perfect.

  • Center of adapter is not milled to the same thickness as rest of adapter.
The inner portion of the adapter was thicker than the outer aluminum piece. It was also not consistent in the thickness overall, it was thicker in the center than the rest of the part. It required a lot of work to get it to the point of being able to make it work. The idea of this part is great but the attention to detail especially on the center phenebolic part of it is unacceptable. I think I have modified my part enough to work but I won't know until I get the engine ready to start. Unless you're ok with paying for something that's not finished and making modification is not a problem for you I would not recommend this part. ... show more

  • Poor fit and finish, wong gasket pattern.
Could not use the bolts included until I deburred the threaded holes in adapter, no clean up was done at factory, so be prepared to do this yourself. Also, as in my photos, the included gasket does not line up and instead forces you to nibble a bit of the carburetor stud holes on the gasket out in order to be able to screw the carburetor on to the engine. Spectre needs to pay attention, otherwise people are going to buy another brand of adapter from someone who actually makes something you can use like it was intended instead of working on the parts you bought to fit that didn't. ... show more

  • Warped inner spacer.
I received this item over the winter and just tried to install it a few days ago. found the inner phenolic block spacer was poorly manufactured and it was severely warped. It would not seal or fit properly without serious grinding and making the surface flat. Poor quality of workmanship, inferior product, should’ve worked right out of the box but completely unusable without grinding. ... show more

  • Good quality, good price
Needed to raise the FItech efi system up a bit for the linkage to clear. This part did and excellent job converting the quadrajunk spread to a standard 4105 square flange 4 barrel. All of the bolts were present to make my application work and the fitment was spot on. Local autopart stores wanted twice as much as this. ... show more
