I got a low mileage Ls3 out of a camaro to go in my chevelle. I got a holley intake and plan on running th eholley terminator x ecu. Will the motion race works throttle body work with this combination or should i get a holley throttle body as well? Thanks for any info

Send the Holley intake back. The stock LS3 intake is excellent for street and is very hard to beat. GM did an excellent job on that intake. Keep the Camaro TB also. Going to a bigger TB will help nothing and make tuning harder. The Holley electronics is a good choice. Contact user @Project GatTagO here on Tech. He’s prolly the best Holley tuner in the country, and used to work for Holley. Enjoy the Chevelle.
