    Rated 4 out of 5 by from Overall not bad I bought this intake for my 400hp vortec 350 goodwrench build. Fitted a 750 holley on it. Bolted fine to the heads casting was correct. Gasket lines up very nicely, i got stock factory intake gasket from felpro. Needs a lot of plugs. Front bolt hole near coolent temp hole leaked but i put a bolt in there with thread sealant and that fixed it. Oil pressure sensor did not fit had to buy an extended piece to raise it above the intake slightly so i could thread it into the block but also clear the distributor. Other than that the intake has really good flow and has a very snappy throttle response on the run stand. Good intake if your on a budget and want the same performance of a higher dollar intake.

    Rated 3 out of 5 by from Could make a decent budget choice with some work The casting is a bit rough on the outside but acceptable for this price range. All the vacuum and coolant holes were properly threaded and I did not perceive any issues with those. The manifold sat almost completely flat with only the slightest amount of tipping corner to corner without the intake gaskets installed. I've experienced worse with much more expensive intakes. I ended up doing a return because the ports are all pretty rough and all different sizes. However, If someone had the time to spend cleaning up and doing some port work I think this could make a pretty solid choice for a budget build.

    Rated 3 out of 5 by from A little rough as far as visual aspects Just got this a week ago. Was looking for a budget friendly option. Viewed this one on Jegs. Looked like it fit my budget and quality looked good by listed pictures. Hopefully it performs better than it looks. Casting is pretty rough and has some spots where carb mounts that I will have to file down. Port holes where all 4 different sizes. Definitely does not have "Jegs" anywhere on it like pic shows. After looking at it further, looks just like the cheap ones listed on Ebay and Amazon. If I wasn't in a rush to get my truck running, I would have return it. I spent some time squaring up the ports and using a file on all the burrs. Apparently it had paint on it also because I sprayed it off with brake cleaner and paint came off. Guess we will find out if its functional soon as I get the truck started.

    Rated 1 out of 5 by from Poor Overseas Quality Control Unfortunately I had to return this manifold. I was looking forward to getting a value price product and expected it to at least perform in fit and function. This manifold was going to be used on 327 with Blueprint aluminum heads. I set it up on the engine and found 2 bolt holes would not line up. They were at least 1/8" off!!! Back it goes, name brand USA made will be ordered once I get my refund.
