390 4/v in my galaxie and i honestly havent counted the miles yet. 351w 2/v in my 79 merc daily driver and it gets 15mpg on the highway. It doesnt have to be a BB to be bad on gas !!!!!!

No matter how complicated something is or seems, always start with the simple basics then work your way to the rocket science !!!

390 4V in my '64 and 10 mpg. Sure glad I don't have to drive it but to the store and back etc. I should have filled the tank rather than put $20 in it back when the gas was $2.75 then I think. It's $3.17 now for the cheap stuff. Still I wouldn't give up my 390 for nothin. Just need a whole dif car that's small.

How 'bout straight blocks? Even though I've got 2 460s and a complete EFI 302 HO in my garage, my '64 still has the original 223 6 under the hood. Why tamper with perfection?...

514 here, originally a z code 390. Keep raising gas prices, I'll keep my big block so when I rob them they can't catch me, kidding kidding, they're robbing us.

The 521 is nothing less than disgraceful on fuel. And at $4.10 U.S. a gallon for the 98 octane stuff,you just about need a bank loan to do a cruise down the esplanade.
But, don,t the jap and euro tourists love it!
Oh, hang on , so do I.

All '63s, all big blocks form a .030 over 360 to a .030 over 428 with a dual quad 406 some were in the middle. Who cares how much gas is? I'm still going to drive one cross country this summer.

390 originally 2v. Now .030 over (396ish) Edelbrock performer RPM top end, crane cam, speed pro pistons around 9.4:1 compression, and a holley 4v 750cfm vac secondary carb. I don't think I need to metion it but it's a BIG BLOCK.

my old 69 429 gal used to get 17mpg


right now in the family:
4.6 06 mustang
3.8 98 windstar
5.0 89 mark vii
289 65 gal
engineless 69 mustang (poor old thing)

on the stands: 71 350 sbc (why?)
68 396 bbc (why?)
69 429 bbf (for the mustang someday)

I'm optimistic that a 429 with some modern tricks will be able to get >20 mpg...and still put out 500 ft-lb. Love that engine.
