I suggest changing the rear gear ratio to 411's with that big block.

That blower with your carb attached will be too high for the hood protrusion restriction they allow in your state.

Enjoy while the fun lasts.

If you keep the paint and body pristine looking, and it is not a daily driver, they may not stop you for it.

cut the top of the fenders and front and raise it up a couple of inches. You would not even have to raised the cowl. hahahahahaha

You might gain a bit of clearance by using BBC mounts if you're using SBC mounts now to gain header clearance.

Lower the engine. You'll need to notch the crossmember for oil pan clearance, and fabricate new motor mounts (the parts that bolt to chassis.) You can get a good inch or two of extra hood clearance. If you get a chance, take a look at an IHRA/ NHRA stock/ superstock Nova or Camaro for ideas.

blown 72 nova

just something to try. measure clearance between crossmember and pan. that distance is what engine can be lowered by using a front motor plate. you clean out mounts for more free area

Really surprised you are going to need 5" for the 177. They are much lower than say a 6/71 or 8/71. Too bad the cops are so tough on this issue. I have a 6/71 which takes up 1/4 of my windshield and all I get is a thumbs up from the cops. I have no expierence with the tall deck, guess they are much higher than a standard BBC.

Like someone else posted, I would look at swapping motor mounts. But, then again a fiberglass hood, especially a lift off should not be that much.
