HOW TO BUILD BIG BLOCK CHEVYS-468 VS 496 (WHAT'S IT WORTH?)

BBC BUILDS-SHOULD YOU GO BIGGER? 468 VERSUS 496 BUILDS-WHO DID IT BEST? CHECK OUT THIS VIDEO COMPARING MODIFIED A MODIFIED 468 BUILD TO A MODIFIED 496 BUILD? DOES IT MAKE SENSE TO ASSEMBLE A 468 WHEN FOR A FEW BUCKS MORE YOU CAN DO A 496? BUT HOW MUCH MORE POWER IS THE EXTRA DISPLACEMENT WORTH? IS A 496 THAT MUCH BETTER THAN A 468? WHAT ABOUT A SIMPLE, JUNKYARD 454? WHAT DOES THAT MAKE? IT'S ALL HERE!

The amount of research and time you’ve spent on these videos is insane. They are literally a bench mark for anyone who’s seeking to build any v8 engine at this point and you should have over 1, 000, 000 subscribers.

What makes a big block so deadly is that power curve! Having that kind of torque on tap that long is brutal.

We built a long rod 468 13.1 with Canfield 310s, Sniper Jr intake, 1150 dominator. I forget the cam specs but it was .748 lift on a 112.. in a 3650 lb car ran 8 90 with a 200 shot. 468s can definitely make power if there pieced together right.

You can finally answer the question "Which combo will give good torque?"
Answer in the case of BBC: "Yes."

Just got a gen 4 496 from my dad that’s been already machined and such. Now to find some heads and get this bad boy going. Thank you for all the good info

[adamspencer]

As always, I’m jealous you get to play with this for a living
And inform people like me
Thank you

I have been waiting for this episode! Big blocks rock the world!

The 496 Stroker is the Big Block version of the SB 383 Stroker. Its magic is more power everywhere and in a stock block saving us thousands of dollars. Thumbs UP!

It's like you know what I'm thinking about. I wish my wife understood me like you do.

[pauldulworth]

I have a friend who wants to build a BBC either 427, 454 or a 496. This video clears up a lot of confusion. Well presented. Thank you.

For someone that has almost no idea what all this stuff is it was incredibly easy to understand. Thank you

Wow best comparo ever I have this same bottom end but with 781 ovals makes 600hp 610lb/ft

I ran both of these combinations years ago around 1982 in a NHRA Super Gas car I had. Car was 3, 000 pounds with me in it. Same heads, same cam, same every thing except one was a 468 then I used the same block and converted it to a 496 which the only difference was the 1/4” longer stroke. I had no dyno but I can tell you the difference in how my car performed. We only ran 1/4 mile back in those days so times and speeds were in the 1/4 mile. With the 468 I ran a best of 9.45 at 144.00 MPH. The 496 it ran a best of 9.12 at 148+ MPH. So over 3 tenths of a second and gained over 4 MPH which is a healthy gain. The real difference was the torque leaving the starting line. I had a nice set up chassis and the extra power and torque made the chassis work even better. I felt had I back off the rend end gear 4.88 to a 4.56 with the 496 it may of helped on MPH even more. It was maxed on RPM for that long stroke steel rod engine before the finish line. It was pushing 7, 800 RPM’s and it didn’t produce any more power after about 7, 400. I loved the 496. It was very dependable obviously had more than enough power for the Super Gas 9.90 class. Heads were just stock LS7 open chamber heads and had a weird intake. Two bolt main block. Crane R274 which I don’t remember the specs it’s been 42 years ago but I believe it was .727 intake a little less on the exhaust. Crane still makes that same cam. I believe it’s 110 lobe center. No nitrous in those days. Back then if NHRA caught even a bracket car with nitrous you were banned from any of their sanctioned tracks. My family now builds some of the countries fastest Pro Mod and Street Outlaws No Prep King engines. We’re on 3rd generation of engine builders and drivers.

Just stumbled on this video while looking around to see which direction I’ll be building my 454. You made me decide on a 496 stroker. I’ve got a ‘66 Chevelle SS that has the matching block in it, runs great but I want a hot rod toying around engine that I won’t be worried about if I crack the block for some reason. I wanted to go all out with aftermarket bigger heads and etc but I still wanted to keep my stock hood with bigger heads and high rise intake, I wouldn’t have the clearance. To be able to get 600hp from the stroker 496 and stock ported heads is what made up my mind. I can keep my factory hood but still make north of 575 hp. Thanks for all the info!

[MississippiDan]

I still watch this video from time to time... Thank you! If i had a dyno, I'd probably never go to the track. 😂

[dejanfreighter]

Beyond words to describe Richards sick attention to details, mind you that compliment comes from a Virgo which rarely compliment underimpressive preople.Any potential question is already answered.Thank you for giving us the knowledge how to build our own cheap junkyard versions into almost a good crate engine from assembly shops which are 5 figures nowadays for a good 454, given a better set of bearings, maybe rods. 😉

[markwallace]

Richard your Awesome you and Engine Masters are my engine shows. I’ve seen you on there as well. And we all know You can never see to many dyno tests !!! Please keep up the awesome work

[patlandymore]

Nice test! Really great comparisons...and wow did that 496 produce. 👍🏼

I opted for a 0.030” over 454 and an 88mm turbo in my FFR ‘35 pickup. All my buddies were saying why not build a 496...I says then I took a couple of them for a ride!!

Funny how having the crap scared out of them changes their tune 😁

[TheIronClooch]

Would love to see some 429/460 BBF content. Awesome video man. Keep it up!

[bigdogsportingtonyb]

We really love the fact that you are suggesting porting the factory heads and porting th ed dual plane manifold. When the porting is dont right you can pick up tremendous power gains and also save some money. This was a good video. 👍
