Absolutely do an 8.1. I’ve been curious about those for years!!! I feel like the capabilities of those is very underestimated. I’m also curious if you ever did a 3.5 ecoboost Big Bang?

[@shitbox7413]

The cylinder heads are the limiting factor with the 8.1, and aftermarket support is very limited...

[@johnparrish9215]

@@shitbox7413 There are aftermarket Heads, Cams, and Intakes from RAYLAR.

[@ChadLisonbee]

Shit Box I understand the limiting factors. But there are options. I have yet to see a set of home ported heads on one or see someone push it to a Big Bang.

[@shitbox7413]

John Parrish, I’m well aware of the Raylar 8.1 parts, their stuff is very expensive, for what it would cost you to buy a junkyard 8.1, and add the Raylar stuff to it, then buy an ignition box to control the coils, you’d have way more money in it than it’s worth. There’s a reason 8.1 swaps aren’t popular.

[@shitbox7413]

Vertical Pedal Garage, 8.1’s don’t have enough piston to valve clearance or guide clearance to accommodate much more lift than the stock cam has, modifications would have to be made for high lift camshafts that would be needed to take advantage of extensive port work.

[@SkypowerwithKarl]

I’m so glad you have so much emphasis on ring gap on boosted engines. The first sign that you really know what you’re doing.

[@troyledbetter6597]

I have enjoyed watching and rewatching your 454 videos! I would like to see a gen 6 turbocharged (fuel injected, stock or aftermarket )454 for towing that would go in my 96 3/4 ton Chevy.

GREAT JOB !!!! I would love to see the 8.1 tests, hardly anyone pays any attention to them.

[@idriwzrd]

Yes to the 8.1L. Richard, your videos are the best.

[@shadvan9494]

I don't remember what episode of engine masters it was, but Steve Brule says "Nothing Beats an LS.. Except a Big Block Chevy". I love the BBC. it is my favorite engine. I have had several over the years, I got my first taste for speed in the early 80's in a 76 Hondo flat bottom V-Drive boat with an LS7 crate long block with a tunnel ram and twin Holley double pumpers. After it dropped a valve, I swapped it to a L88 out of a corvette. I currently have a LS3 396 in my 71 Camaro that has be warmed over quite a bit. I am currently looking at building a new 496 to replace it.

[@ChristopherGaul]

Absolutely want to see you do something similar with the 8.1L ! Though I'd like to see what you can get out of the factory EFI before you switch to carb.

[@patlandymore7035]

Any big block test is a great test, so count me in on the 8.1 too!

[@timoneal9654]

Thanks Richard. Just what I wanted to see. A video wish list does include the 8.1L with similar steps. Also, more on this motor with turbos before the head swap but understand if you go the other way. Perhaps a roots blower too if there is merit to this.

[@troystuart8601]

Great video! I have a L29 454 in my '96 K3500, 290 HP ain't enough!! ;)

[@staninoshawa]

Great channel. As far as the trending lean I'd put on a larger volume hat with the hat facing straight forward or rear, 0.024' HSABs, again use the vent tube extensions just inside the throat to the carb hat. yes use the BAPV WITH 0.080" PVCR holes, open (drill) the channels feeding the boosters as large as possible without compromising the booster. Since the metering blocks have replaceable bleeds inthe main wells, be sure the 2nd from the bottom is plugged and the bottom one is around .020". let me know how it works out.

[@johnmillican3182]

Nearly 15 psi at peak torque on a 9:1 engine has me curious about the fuel type used in the dyno testing. What would this combo net with pump gas tolerant boost levels? Love the videos, Richard. Very informative without the BS.

[@kencaven9080]

I’m going to add a intercooler to my 363 CU IN SBC currently running a Pro Charger and making 762 hp. Maybe adding about 40 hp and hopefully increasing my mph from 192.045 to over 200 mph at Bonneville.Salt flats. Great video and information thanks

Stupid thankful the KZbin dieties deemed your channel worth for me! Getting through your backlog of videos as quickly as I can! Was wondering, could we get a video on cam swaps for Smog vehicles?

Mctig Mctiggy we don’t have e85 where I’m at, the nearest place is ~110 miles away and that’s no good for a daily

[@ts302]

This topic peaked my interest. IMHO, I believe it's the pressure within the cylinder that will determine the knock threshold of any given fuel. How that pressure is created, high CR, high CR & low boost, or low CR & high boost should not matter as long as the tuning is optimised for the combination. Theories are great, however the BS stops on the dyno/testing. Please Richard make this happen. Thank you

Now the real test: how many miles can it run with that?😅😅😅 Also love the video! I'm prepping to build my first motor which ALSO happens to be a 454 from the junkyard! While I'm going for a twin turbo setup, its great to hear how much power you can get from simple stuff like a camshaft and intake, so sounds like I can just drop the motor in with those and then wait till I get the turbos for my next speed fix! Little question: I have a gen IV, NOT a VI. Are the upgrades the same? I know the 70s 454s were notorious for low compression. Any other upgrade ideas?

I would love to see a 8.1 test. Maybe a Mercruiser HO, or some Raylar stuff?

[@hobbesnmina2001]

Richard been meaning to suggest a dyno test based on equalizing power of different cubic inch size motors via supercharger boost. It would only be valid supercharger since they are driven by a pulley ratio. A few years ago I made an Excel sheet using supercharger volumes and ratios. One can enter the bore and stroke and see how much boost the blower will make and also pounds of force via boost per square inch. I did it to see the differences between engine combinations in nostalgia classes were a 6-71 blower is allowed. The feedback is super interesting but it would be an awesome addition with known dyno results! If you are interested I could send you a copy of the spreadsheet. I’m always looking at the different boost results in your dyno runs when you test different blowers and a class with a single blower allowed and a max drive ratio the blower is an equalizer. The bigger engine will make less boost and the smaller engine will have more boost. 454 vs 350 example. Then there’s bore vs stroke with a blower as the shorter stroke larger bore will have more lbs of force vs the torque of a longer stroke smaller bore combination. Thanks and take care Carlos

Richard, can you explain how dynamic compression works when adding boost? As you know in a NA application, cams are designed to work with a certain compression ratio. But it seems like this gets thrown out the window when you add boost to the equation. How does this influence cam choice?
