Don't confuse this carburetor with the 66 chevy II and others with 275 hp and a holley it only has 1 1/2" plates.
We use the 67 327/300 comb in the Sunfire my son drives. In our case the holley is better due to the hp factor, but may not work as well in all cases.

Yes, the 66 540 Holley should be rated about five more than the 4GC, but so far, NHRA doesn't want to hear about it.
