How to make horsepower on pump fuel | fullBOOST

Horsepower levels that were once thought out of reach for street based naturally aspirated engines are now becoming reality thanks to Australian companies like Higgins Race Heads. Ongoing research and development has resulted in a proven 900 plus horsepower small block Ford capable cylinder head and intake manifold
solution.
Now it’s one thing to achieve this on race fuel but this combination is making the numbers on regular pump 98-ron unleaded petrol.
This 461-cubic inch street Windsor V8 was purposely built for these Australian manufactured Cleveland style heads by Melbourne speed shop Dandy Engines. It features a 13:1 compression ratio using forged Diamond pistons and Oliver connecting rods. With input from Gale Powley of GP Technologies, Higgins Race Heads offer both the head and intake CNC ported components straight out of the box, flowing well over 400cfm. It’s important to note that this is not a bespoke race cylinder head, but an off the shelf complete ready induction package for pump fuel street cars.

Ray Oddman Bob Glidden won a lot of races by cheating using a Sneaky Pete Nitrous system, turned in by his two sons , RUSTY AND BILLY , due to an argument they were having. According to Billy in a magazine article interview

[@johnhickman7922]

Al Mierz That wasn’t with the 351C. That was later on when using a 499 inch BBF Wedge. By then, most racers were using juice. The “Dodge” boys, Alderman and Geoffrion were the ones that won a bunch of races on juice, hence their shop getting “broken into” and “vandalized.” Heck, Alderman had two nitrous backfires on the starting line, which really made people start to wonder. When Glidden went to the 429 in 1982, his sons weren’t old enough to race with him professionally yet. So yeah, he spanked ass with the 351C without using juice.

Cleveland heads. Flow baby flow. This is why the 351c is so loved. The flow of the heads that are available now thanks to cnc and computer design are phenominal. I can remember spending hundreds of hours of hand grinding and matching on ports anything nearly 2/3rds as high a flow as these head and intake make. Hand p&p and intake and exhaust girdles along with great valves and valve springs make some amazing Hp. Breath baby breath!!!!

@@trixnhoez2964 well said and i agree brand loyalty is honestly just childish..... all V8s are badass

[@Firion13]

Brand loyalty is total ignorance. Engines are just air pumps. They are all doing the same thing. And if you throw money at them regardless of the manufacturer you can make more power. Weak points can be replaced. Restrictions can be removed. The Cleveland engine is interesting in particular. Big block Chevy styled heads with canted valves that sit on top of a small block. There actually wasn't a small block head by any oem manufacturer that could stand up to the Cleveland head's flow until 1997 when GM debuted the LS1. They we're matched with the boss 302 block in 69 and 70 for trans am racing. And in 1970 the Ford boss 302 mustang won the trans am racing championship.

[@brockmaine2743]

@@Firion13 well to be clear ... in my opinion there's nothing wrong with being loyal to one brand and what not. The problem I have is when people are assholes about it and hate on other brands simply because it's not what they would buy or own, I'm a chevy guy and always will be but I do like dodge and ford aswell. 9 out of 10 people are just too prideful and say they hate this or that and have never even owned another brand, they just hate it because most likely that's what their father or mother owned so they feel like they need to own it aswell. When I see or hear someone hating on a certain brand I always like to ask them.... which would you like to see win a ford dodge or chevy V8? Or a Japanese brand? Then they come around and the brand doesn't matter anymore lol I don't hate Japanese cars but I know I'd rather see an american V8 (no matter the brand), whoop on the Japanese cars haha BTW ford guys are the worst because the true ford guys are so damn ignorant they absolutely HATE chevy and idk why because Chevrolet is probably the biggest name now days in drag racing and street racing.

[@carterlee3427]

I have to disagree. I don't like Chevrolet because they refuse to offer quality to their customers. Chevys fall apart. After only five years you'll be wearing your headliner on your head in a Chevy. The engines are pretty good and they go a quarter million miles if you take care of them. However, the rest of the vehicle will look like it was digested by bacteria at only half those miles. I drive a twenty four year old f-350 and it still looks almost new. It is an exquisite machine and a testament to customer value. But, the rivalry is fun. And, the more ridiculous people get with it the more fun it is. But, you'll have to excuse me because I have a candy ring and some fun dip and it's time for me to go and have a real treat!

I have to believe it's at least $25K

[@fread51]

Think about how nasty a 900hp 5.2 flat plan crank would sound

[@ronwest7930]

Pump gas with 13 to 1 compression? impressive numbers though.

[@matthewsmyk9091]

when i turn the aircon off - i make this much in my Honda.........

[@alycestapleton]

Matthew Smyk I’m sure you do .honda’s are rubbish

[@matthewsmyk9091]

Gaz Girl - its like shooting fish in a barrel!!

[@rickkowalske4116]

This engine makes more power on one cylinder than all of your hondas

[@393boss]

wonder how much More HP this 461C eng combo would make with a longer (1.52) rod in it? with a good dual carb tunnel ram it should make 1000+HP n/a

[@arkhsm]

Check out Alon Vella's multiple Aussie Drag Week Challenge, to see his near-identical setup running a best of 8.49@160 ! Street Machine Magazine has a great article on this combo !!

[@Johny3xtra]

So what do numbers look like for big block ford running higgins parts ported to the max. And using a belt instead of chain. And bigger valves and taller lift with aluminum rods and of course best cam for high end power and four bolt main on all five mains full build all the tricks in the book roller rockers and all that on 460 junkyard virgin block. And would it handle twin turbos. PROFESSIONAL COMENTS ONLY. This smal block made almost a grand hp the big block without turbos shld have way more rite??

[@mach5jeep]

Isn't this what we used to call a Clevor?

[@chrisoh6627]

What's the hose from the rocker cover to the pump thing for? I've seen a video of a 300whp NA Honda make an extra 5whp when they attached a vacuum cleaner to the rocker breathers lol. Is this a similar contraption haha??

Vacuum pump

[@Rome3aaro]

Mick D how does a street motor need a vacuum pump.. 😂

[@lop8828]

Rome3aaro because too much cam imbecile. Now do you want a good vacuum to the brake booster or run over the crowd.

[@gordowg1wg145]

BOO' that's a bit harsh when you are as ignorant - while some vehicle will use an auxiliary vacuum pump for the brake booster/servo, that is not what is shown here. It is a vacuum/scavenge pump used to create a low pressure in the crankcase to reduce windage losses. It is increasingly common to use a hydraulic servo' on modified vehicles where a hydraulic power steering pump is fitted, as the pump can be used for the servo' as well as the steering rack.

[@phillipdolliverjr.8656]

What did this engine build cost?

[@POLITICALYCORRECTify]

Can someone tell me how the bloody hell do those guys in Street Outlaws get 1500 hp? I know they use 6 litre big blocks with pro chargers or twin turbos, but i see other cars with that size motor and prochargers only giving around 500 - 600 hp? How the hell do they get well over 1000?

[@dennisrobinson8008]

Boost.

[@joeyvoyles5548]

I just want to know and I'm from the US how do you run a 13 to 1 compression on pump gas I don't want to seem stupid but I really want answers

[@alexb6018]

With Factory heads we ran 11.7. Add Aluminium and it is worth a point so 12.7. More modern Combustion Chambers than the Factory Heads and add a bit more. With the better more modern Combustion Chamber Flame front propogation is better so not as much timing needed so safer. Then ultimately, to get an engine making big numbers comes big Cams. Big durations vent compression so static Comp is a Big number but Dynamic Comp or Cylinder Pressures come down the more duration you have. I hope that helps. By the way, our built for Street Strip Clevo's are running Mid 12's:1 quite often on our 98 RON which is US 93. with no issues at all usually with cams over 250deg@50" and total timing of 26-28deg. Cheers. I hope I gave you a decent explanation.

[@victormuff7024]

what's it like down low say 3700 rpm ?

[@reminoel483]

I wish we had pump98!!! Up here in canada all we got is 91...

[@fullboost]

Your fuel is measured differently (AKI) so the equivalent of our 98 would be 93 in Canada. 👍

[@ziojay6376]

Yep, 9000 RPM!! First step: plenty of money.

[@craphittingthefan9445]

That motor should run a 9 in my car so when can you ship It to me?
