These are made in the USA beware of Chinese knock offs that even copied our description. They are made from an inferior material and the dimensions are incorrect.  We ship from the west coast priority mail within one business day many times the same day order is received. Not from China.

Thank you in advance for reading this.

Do you Have a engine with a TBI manifold? 4.3, 5.7 and 454? Don't have the computer and wiring harness? Or just want to convert to a carburetor. This is the part you need .

Works with 2 barrel 350 and 500  CFM Holleys and early autolite carbs.

Includes

Mounting hardware nut's bolts washers ect.

One holley 2bl base gasket

One TBI base gasket

It's hard to see in the picture but the bores are tapered to adapt the narrow 2bl spacing to the wider TBI pattern without hurting performance and airflow.

Made from a durable heat resistant composite automotive approved material gas and alcohol proof won't chip crack or stain. ( You would have to use an Axe to damage this material) 

Acts as an insulator to prevent the gas from boiling (Vapor lock) and keep the carb cooler for more power. 

Also adds tuned length for more TQ.

Made right here in the USA on our in house CNC machines.
