Making Serious Power on Retro 5.0 With a Trick Flow 11R Top End Kit

Trick Flow's 11R heads are the modern twist on the venerable Twisted Wedge cylinder head design. We dyno tested them on Retro 5.0 to see how much power they were worth over the typical Twisted Wedge, and, just like we thought, they make solid power. #engine #ford #dyno

Very interesting retro throw back. Appreciated the 80s vibes in editing.

[@bruceferre6232]

Hey this video hits a little home for me! I have a 1991 fox with trickflow heads, b cam and a Holley systemax kit on it. It also has a Paxton supercharger so it’s definitely old school. It’s bbk headers to catless x-pipe and flow master muffs. I’m getting it tuned with a quarter horse as we speak and should be on the road soon! Awesome video!!!

[@yonson_racing]

Impressive results Donut! Keep up the good work!

[@EngineLabs]

I'm tryin'!

[@passinggear]

You had me with that sport coat....!

[@EngineLabs]

You can't really see it, but I'm wearing the matching pants, too! No boat shoes, though. LOL

[@Bacongrease00]

Great video! E7 heads choke so bad. Now you got that air moving!

[@EngineLabs]

Gotta love those little 127cc intake ports!

[@troycarter4742]

Great to see some retro 5.0 Fox content. The article was a nice detailed read too.

[@EngineLabs]

Thanks Troy!

[@themrfabio2459]

Love the 80s theme editing. Awesome work

[@EngineLabs]

Thanks!

[@adambergendorff2702]

Good video! Short and to the point, I also liked seeing those stock heads go in the dumpster!

[@EngineLabs]

It was hard, since our hoarder tendencies are to keep them on a shelf for 20 years, just in case...

[@Rocksoup77]

I have this exact kit ready to go on 92' mustang convertible. Motor has 100k and runs great. I may freshen bottom end up when I do HCI install just to get the most out of it. These numbers are impressive to say the least. I have the TFS track heat intake instead of the holley like you have. The holleys are tough to beat. Great videos and content! Look forward to more.

[@EngineLabs]

We were all super pleased with the top end kit. To the point, that we almost called it done right there. That will be a fun combo in the car, for sure!

[@TheHortond]

The internet wasn't even a thing when my Mustang was built.

[@MrAnthonyfym]

We has to read magazines and believe what the summit catalog claimed

[@EngineLabs]

Aren't you glad it is now, though?

[@xmo552]

I still love love LOVE my little sbf 302.

[@EngineLabs]

Same here!

[@kevininge1219]

Down t watch ready t see what it makes. You should run different cams ford e b f and a small solid roller something from Howard's right out the catalog old school. Like to see what different injectors would do factory fox 19s vs newer explorer 4 hole 19s 24s on up. Kenne bell would be awesome to hear. Procharger ps14 d1 hell yeah badasst automobile ever made. Keep the noise up put in a car and let us see it run. I have these heads 11r 190s cnc street. 30over matching # shortblock. But still lookn em in their boxes working my way to it

[@leroybrown7494]

Great video series 👍🏼 I bet a bigger cam it would have easily made over 420 , my ls engine makes great power i just wish i could get it to sound like a basic cammed sbf

[@EngineLabs]

Thanks 👍

[@fatheadmeetoo2891]

I might pull the trigger!

[@aaronliddell4280]

Where did it make peak power? Love the 80’s theme 👍

[@EngineLabs]

Peak torque was at 4,900 rpm and peak HP was at 5,800 rpm.

[@kermieplaud1162]

Nice!!!

[@Jim_Lawrence]

Long Tubes! Add power everywhere...

[@EngineLabs]

They're coming, but we put those shorties through the wringer, first.

[@msk3905]

Yup made a significant difference when i swapped them in place of my FMS shorties! I ran the old Twisted Wedge heads and would have loved to run these 11rs if available

[@crazyhorseracing6130]

What size injectors are you using? Thanks for the videos!!

[@EngineLabs]

These are Deatschwerks 78 lb/hr injectors.

[@msk3905]

Stout numbers but I would have run a comp XE274HR cam in that combo

[@QuikModsOBS]

Are these the best option to squeeze the most out of sbe 302? Or are there better option top end package wise

[@EngineLabs]

"Best" is such a loaded term. But the 11R top end certainly works as advertised, and then some. I think with a larger cam, the engine would wake up some as well, but with the stock bottom end, PTV clearance might be an issue with a larger cam. I'd definitely be happy with just this N/A package in my SN-95, no doubt.

[@Carcrafter7165]

How high did you rev to on the rpm on the 5.0 I love it like it is N/A.

[@EngineLabs]

We spun it to 6,500 rpm with the Trick Flow cam and heads.

[@robaxelsson530]

What ECU / System is this ? Speed density? I didn’t see a MAF sensor on that intake

[@EngineLabs]

It's the Holley Terminator X Fox Body plug-n-play.

[@johnnymula2305]

I have a 5.0 roller. I have the twisted wedge 11r top end kit. With a 347 stroker, 750cfm carb. What do you think i would be looking at as far as power? Its going in my 86 Bronco. Its backed by a Len Tech AOD trans.

[@EngineLabs]

At what compression ratio? Also, in a Bronco with an AOD, I'd guess you probably won't be spinning it nearly as hard.

[@johnnymula2305]

@@EngineLabs compression is 10:1 Im in AZ. The summers get ridiculously hot. So i didnt want to struggle with detonation issues. Im not planning on racing it. I’ll pretty much be in the 1500-3500 rpm range 99% of the time.

[@justinkostelecky6201]

What size were the intake runners on those 11R’s?

[@EngineLabs]

170cc. They are the small version.

[@jarez3781]

What size of headers did you use? And what brand?

[@EngineLabs]

I should have mentioned that. They are 1-5/8-inch JBA shorties.

[@cgip1220]

What trick flow head and cam can I use with stock 302 pistons

[@EngineLabs]

There's too many variables to say with certainty. You'll have to measure piston-to-valve to be sure, no matter what.

[@arkhsm]

Give them a call, I'm sure Trick Flow could tell you !!

[@CCWFOX]

Do the pistons need to notch to run these heads

[@EngineLabs]

I'm not sure, because we are using an aftermarket piston. Since the Stage-1 cam is small, there is a chance everything will clear with a stock piston.

[@pimpovic2]

That's about 350whp, that's not bad on a Stage 1 cam.

[@KingJT80]

and they'll break 450 with that blower.....be cool if they did the kenne belle 2.1 with 10PSI and these heads....

[@EngineLabs]

@@KingJT80 If we could have found an old Kenne Bell, we might have tried it!

[@KingJT80]

@@EngineLabs I think they started selling them again.

[@michaelmayer8618]

You probably down a little horsepower from what they advertise bc you're running a full accessory drive which im sure they didn't n the torque is higher bc of the longer intake runners

[@cgip1220]

did you change pistons? doesn't have same 4 eyebrow

[@EngineLabs]

We did. We went to a stock-bore forged 2618 piston right off the bat to handle the boost that's coming, and had valve reliefs to work with the 11R heads.

[@user-fm5wq5wm7x]

Could you put a spacer underneath the intake to break 400 hp ???

[@KingJT80]

it made 411...the kit claims 432 with the carb....not bad...

[@adamrushka8096]

Adding even more runner length would just make more low end.

[@EngineLabs]

There was a spacer of sorts (it was a capped-off nitrous plate) between the upper and lower intakes to clear the fuel rails.

[@maga7579]

What cam?

[@EngineLabs]

Trick Flow Stage 1

[@AC-bl1rl]

roller rockers?

[@KingJT80]

gotta have em on these heads. i dont even think they have a pedestal mount version...could be wrong. im looking at them for next yr

[@EngineLabs]

@@KingJT80 I'm 99% sure they are only available with 7/16 studs. I've gotten spoiled by pedestal mount valvetrain.

[@Bacongrease00]

It’s gonna make 520-560hp on the vortech

[@EngineLabs]

You might be surprised... 😁

I’ll never understand why so many people put heads on the block when it’s on a 45 degree angle. The engine stand rotates people.

[@EngineLabs]

Ummm, that's a dyno cart, not an engine stand. It doesn't rotate.
