Carb and TBI Spacers
from High Velocity Heads (HVH), and Brzezinski Racing

Carburetor Spacers and GM Tbi Spacers are not all the same!

Most function to raise the carb or tbi only, with no regard to air/fuel flow properties. Ours are specifically designed to maximize air and fuel flow!

We Offer the Most Powerful and Highest Quality Line of  Spacers and Adaptors Available!!!

Different engines need different spacers! A tbi spacer or carburetor spacer that works for one application will not necessarily work for another. In fact, it usually doesn't ! We know what it takes for tbi and carburetor spacers to make hp!

 Do the four spacers below look similar? No! They are for 4 different intake manifold to carb / tbi configurations.  We have many, many more available !  

Come on in !

Find one that is right for you!

   Here are a few of the comments customers have sent to us:

"Adapter plates (CFM-Tech ported) are doing well.   Everyone is pleased - including us. All have had feature wins with them.......just thought i would drop you a line." J.B. - circle track engine builder

"CFM-Tech is very helpful. When I needed more horsepower I went to cfmtech and they supplied me with lots of ideas to gain more horses. They custom built a carb spacer for me and boy did it ever help. The first race after I put the spacer on I won."- Jon, MN- 351 2bbl

"I installed your 1 inch (CFM-Tech ported) spacer...It was like night and day...The 21 foot Wellcraft hits plane much faster and is at least an honest 2 mph faster.  The engine turns 300 more rpm at WOT. You made a believer out of me...I'm more than satisfied." - DK, Fla- 4.3 2bbl

"I would just like to tell you that I am extremely satisfied with the spacer. It took almost a second off my 0-60 time. Added more top end power. It's a great product. Thanks." - RR,Fla- 5.7 Tbi
