Question of the Week: Tell us your favorite big-block


You wrote: “Regardless, the Olds 455 when properly dressed was a beast. Enough to torque to beat any other motor at the drag strip on a given day.”

I don’t know about that. The Buick 455 was a real torque monster, too. 510 lbs. ft of torque!



And for uniqueness, how about the 425 Buick Nailhead engine? No other engine looks like a Nailhead.



I have to go with the Boss 429, wrapped in a ‘70 Torino with 4 speed drag pack.
Small block: Boss 351 in either a Mustang or Torino.

My favorite was the Pontiac Ram Air 400. I purchased it new in my 1969 GTO Judge that I have owned for 50 years. I love my GTO Judge.

And then let us not forget the most misunderstood, least known ever Chevrolet engine which is shrouded in mystery. In fact, it’s called the Chevrolet 427 Mystery Motor for a reason. By the way, it is NOT a Mark IV 427 better known as the Big Block Chevrolet. These fall into the category of unobtanium!


Tough question, there are many favs. I would go with the 396/402, 427 & 454 block. Personal experiences; my late great uncle taking me out west when I was a kid in his '68 Camaro RS/SS 427/390hp to my hs days in my gf’s dads '69 Caprice 396/2 bbl to my hs buddies '69 Chevelle SS396/375hp L78. The sound of those solid-lifters was intoxicating!

Even though I am a Ford Guy and love the FORD 427 SOHC did I miss something or did anyone suggest the Corvette ZL1 !

I did but I just said the Chevrolet ZL-1 since it was also installed in Camaros.

got one in my 69 mustang!!

Mine is in my 68 GT500KR

You know if gm sold the zl 1 over the counter and how many camaros they put them in?

I do believe they sold them thru GM Parts. There were 69 Camaros made in 1969 with the ZL-1 engine.

Caddy 472. I didn’t love the coupe deville but I could open the hood and listen to that 472, it was massive. Sold it about 5 years ago.

69 ZL-1 Camaro sadly only 2 Vettes, or The L88 Had No Match, Period69-camaro-copo-zl1-brighton-motor-800-640x400


Also 61-'63 Long Before GTOs,SS 442,GS, etc. Pontiac had a monster 421 SD That Owned Nascar, Before anyone had a 42x anything421sd

Absolutely have had 5 Mopars with a Hemi in them the ultimate

The 426 Hemi is the clear all-time great, but my personal favorite is the Mopar 440. A little more displacement, a little simpler, essentially equal up to 4500RPM (higher with head work). Just a great big-bore/short stroke workhorse.

Other greats: the Buick 455, Ford 385 family (429/460).

428 Ford is the one for me. Number 1
