What size Holley 4150 or similar for engine?

The TQ can be a bit tricky on the single plane with that cam. You'll have to work on it.
IDK about the Street Demon carb. But a Holley on top, a DP 750 would be a great start, would bennifit from intake mods under it.

That TQ model number is????
There excellent street strip carbs if you can dial it in.
