FULL DYNO RESULTS on this POWER ADDER BBC Stroker. Using a cheap Gen-V 454 core from the junkyard, we built a Multi-Purpose 496 stroker. Using the right combination of parts, we were able to make BIG power then run Power Adders for even more HP! Here in Part 1, we ran the motor NA then with a healthy dose of Nitrous. Part 2 will cover a 6-71 blower and Procharger Centrifugal Supercharger.

It’s so rewarding to see a person like you, with all the experience and knowledge you have, talk this things about cast cranks. Maybe someday the people will learn that even a tire shake can break a crankshaft, but not solely power. Great content as alway!

That torque and power curve is what dreams are made of. That would have such great street manners, and still be quick.

Big Blocks are the way to go if you want overall power. I eventually want to go with a big block with a huffer on my rat, but I will have to sacrifice a lot of mpg, and a transmission.This is gonna be fun to watch!

Richard, thanks so much for your knowledge drops in each video. I too was taught the rec port, steel crank and forged parts and a 4 bolt main being the only way to go for power. But found the task daunting when piecing together my first BBC. Thanks for clearing the air on all that. Gunna save me ton of money putting together my build and putting the money in the more important places instead of buying parts I won't ever need for my pump gas boosted build.

Just recently found your channel and really like the BBC content. Having been racing close to 40 years and your information closes the loop on a lot of what I've learned in that time. You said you've never seen a crank break just on power... On my "Shelf of Shame" I have a Bill Miller connecting rod attached to a BBC steel crank journal from my first big nitrous engine explosion in my drag boat around 1990 or so. Broke the crank into 3 pieces. Wasn't exactly just due to power, we detonated the motor due to not retarding the timing for the nitrous. I've run N/A, blown alky, blown gas and nitrous. Nitrous is still my favorite power adder. I've been racing drag boats with it since 1988 or so... Keep up the great work!!!

Hi Richard, big fan of your articles and videos! I love your comparisons, test and results showing how many different paths to performance enhancement there is! I like the variety of makes and power adders and have believed that engine or car doesn’t know what name it has! Amongst all I have a weakness for BBC with a power adder. It would be cool to see how close in performance at ~1-1.2k HP overall power curve would be between compound or combined combinations of power adders. Not which makes more power but more and repeatable power under the curve! Regardless the path love your articles and videos, good luck and keep up the good work! Carlos

Has 320cc Edelbrock heads and a Brodix 4150 single plane so obviously in the lower 9:1s for compression. Should love the adder though 😏 I’m hoping it’s in the 575-625hp range but we’ll see…always been a nitrous guy but really want to ProCharge this one🤘🏽I know this is a year old but any thoughts on my setup Richard Holdener?!

Speaking of heads. My theory is you can never have too big a heads. If the heads flow too much put in a lower duration cam to match the peak rpm you want to run at. Would love to see the comparison in power curves. Take like a big set of Brodix heads and run it with a 212 -224 kind of duration cam vs a set of stock heads with a 275-275 cam.

Going to test this theory with my nephew - we have a '97 7.5l(460) BBF on the engine stand that's getting swapped into his Mustang next winter, and we're going to throw a set of Kaase's new bad mofo SR-71 heads on the stock short block(fly cut the pistons if necessary) for the first season with the big block before we build it next winter(or find a good deal on a used race short block w/ an aftermarket block - aluminum would certainly be NICE)

@timothybayliss6680 4 жыл бұрын

A few years ago, car craft did a test with ported Ls1 heads vs factory ls3 heads. Same cam, truck, camaro and ls2 intake on ls1. Truck and ls3 intake on ls3. The Ls3 was about 20hp up at the top end but more than 20ft lbs down at 3000 rpm and didn't pull ahead till 5k. For the strip, their computer simulated numbers using ls2 vs ls3 intake were within a tenth and 1mph, the ls1 ahead but around town the with the higher torque farther down, the author thought it wouldn't even be close. If you were to put these heads in this test on a 427, they would leave a ton on the table compared to something like a set of edebrock 454-O heads on a street driven engine. The torque difference at 3000rpm would be closer to 40 ft lbs, the camshaft doesn't have the lift to make use of the high flow these heads offer.

@lukestrasser 4 жыл бұрын
