This guy is great and helped me alot. Before the 700r4 passed on, he said it would be best to get a quadrajet carb. Now that im swapping the t56 he said it would be best to get a holley 750 dp with mechanical secondaires. Whats best? thanks alot

 

I'd probably use a 750 DP. That engine is pretty similar to mine.

 

A quadrajet is a good carb, and works great for an automatic. To get more response on a stickshift car however, a double pumper tends to work best. So both of his suggestions are good. With the T56, as Apeiron mentioned, a 750DP is a good choice.

 

Edelbrock or holley? Im leaning toward the holley. What do yall think?

 

Edelbrock doesn't make a double pumper.

 

My bad. I feel dumb. Everyone point and laugh haha

 

We'll put it in the "no dumb question" pile.
