Hiff 44 card hitting firewall

[Robear]

My carb is hitting on the firewall. Not sure how to fix it. Would be able to adjust the subframe or suspension to fix this?

Carb hitting the firewall?? You might have an engine mount/upper engine stabilizer issue-check the bushings for wear or maybe the wrong intake manifold is installed. If those are in order, you have the option of installing a thinner phenolic spacer between the carb and manifold to move the carb closer to the head (and farther from the firewall).
