Big Block Ford P51 headed 429ci Engine dyno

Nick Kollis 429ci BBF built and run in on JSR Race engines dyno.

[@CoyoteFTW]

Love the 429/460 385 series insane power potential

[@raginroadrunner]

They havent won anyhthng. Chevs run all over them. And no one can tell me why!

[@steevestgermain2965]

Ford 💪💪💪

[@kerryperkins2989]

What an awesome sound.

[@michaelbower2117]

Really given it a workout

[@jamierose4088]

I bought a 1970 Galaxie with the 429. $2000. Mid 14s in the 1/4 & 20 miles to a gallon. The 428s got 14 MPG and were slower. I never got why. Unfortunately the frame rusted and the 429 ripped apart. I still wish i kept it. It was a beauty.

Hope mine gets that kind of mileage lol big block twin turbo with a 6 speed

[@christopherfriedberg6597]

Thought I heard piston skirt slap at idle. Engine shouldn't be dancing at idle either. Check for debris in the pan and filter just to be sure. If it's good, run it like a scalded Mustang !

[@eddiehennig7835]

No doubt they found your assessment of their 715hp engine they built to be totally invaluable 😂

[@marcushills8763]

What kinda cam specs on this? Sounds healthy but not too crazy. I'm curious to see how it compares to the 598 we are currently putting together.

[@MsKatjie]

forgive the ignorance, but was it not drawing out the pump shooters?

[@carterlee8344]

Super!

Here’s your new motor she has 300 dyno hours now good luck

If you look really close at the LS engine it resembles a small block Ford 351 windsor more than a resembles A 350 small block Chev..4 bolt heads, similar oil systems..almost identical bore spacing. Heck even the LS heads will even come within a hair of bolting on a 351W block.. The LS bottom end resembles more of a modular bottom end..Yea superior to the Windsor bottom end.. And the LS heads are light years ahead of the Windsor for efficient easy power. IMO Ford could have been where the LS is in the aftermarket if they'd had done an updated small block with the same bell housing pattern.. OHC build power but people like simplicity.. My 2 cents

[@Frank289100]

THE LS IS COMPLETELY BASED ON FORD DESIGNS. IT'S A REGURGITATED 427 HIGH RISER FORD AKA RAISED PORT 351 WINDSOR. NOT ONE DESIGN ASPECT OF THE OLD SMALL BLOCK CHEVY LIVES IN THE LS. THE LS IS 1000% BASED ON FORD DESIGNS. CHEVY COPIED FORD, BEING THE MOST CRIMINAL THING TO EVER BE PERPETRATED IN THE RACE WORLD. ASK YOURSELF HOW TO EPA ALLOWED THEM TO GET AWAY WITH MAKING A RACE ORIENTATED SMALL BLOCK FORD. GM HAS HAD THE EPA IN THEIR BACK POCKETS FOR DECADES PUTTING PRESSURE ON THEM TO HIGHLY REGULATE FORD AND THIS IS THE REASON FORD WENT MODULAR. ONCE FORD ABANDONED THE PUSHROD MOTOR, IS EXACTLY WHAT GM WANTED SO THEY COULD REDESIGN THEIR SMALL BLOCK USING THE FORD WINDSOR DESIGN PUTTING THE HIGH-RISER PORTS ON IT. SOMETHING FORD COULD HAVE DONE DECADES AGO BUT FROM STRICT EMISSION REGULATIONS PUSHED ON THEM BY THE EPA WITH GM HIDING BEHIND THE CURTAIN IS WHAT TIED FORD DOWN FROM DOING IT.

[@gordocarbo]

block and bottom end was modeled loosely after the Northstar...taken from the LT5

[@CoyoteFTW]

Ford Mod motors make more power stock heads and blocks breathe better and block strength is by far superior.. LS has excessive internal oil leakage due to cheby junk design another issue GM used “communication ports” or windows between the cylinders, above the main bores, but that leaves very little metal to hold the main bores and cam tunnels in place and can lead to wear problema in the LS the cam and crank are like noodles in there, and it wipes out bearings and lifters. This is why Richard maskin of dart machinery to said that LS was the most pathetic engine he ever worked on I agree if Ford would’ve updated the 351w modernized it the LS swap would never of been a thing.. you are absolute right about people wanting things easy they can’t be bothered to learn dohc engine even if it’s far better for making power… it’s the human way average person doesnt know back then one person built a whole car now there’s 30 different guys for every part.. people don’t like to learn no real passion

[@KR-qs3rt]

@@CoyoteFTW I agree 200% with everything you said.. Even the Amsoil Engine Challenge forbid the modular against the OHV engines. No way they could compete against a modular. My point was the swapping of LSs into Mustangs makes me sick.

[@brianb8489]

More like the LS copied the Cleveland being they have similar strokes, bore size and deck hight.

[@Tenn1972]

Could you guys tell us what the compression is and if this is going to be a race motor or otherwise thank you!

[@Tenn1972]

Wow, I just saw the compression ratio down below. 11.4:1 is simply amazing for a pump gas motor what incredible power are you running 91 or 93 octane?

[@saraco429]

Australian 98 RON...The equivalent of US 93.

[@Tenn1972]

@@saraco429 Thanks!

[@eb347]

Can someone tell me why only 2 of the 4 pipes are glowing on that one bank?

[@eddiehennig7835]

Impressive numbers and it sounds awesome! I'm curious why you chose a 429 crank instead of using a 460 crank to get 30 more cubes out of it. Did you use an off the shelf piston or have custom pistons made and did you have to fly-cut the valve reliefs deeper for the P51 heads?

[@alloyrat]

Chipmunks arrived! 7:12

[@donaldhalls2189]

Sorry mate couldn't really tell what was going on, sounds OK but didn't see any horse power or anything, thanks for your time, all the best to yous and your loved ones

[@coupe545]

This was mainly a run in session, HP is shown at the end.

[@raginroadrunner]

The 460 eats crank bearings.

[@raginroadrunner]

Should have used a cross bolt with bolt main cap.

[@bobg3034]

Carb is not set up right! Fuel is being pulled out of the accelerator nozzles doing the full length or the run. Cab needs anti pull over nozzles!

[@danonoveh8114]

Something screwie going on with that engine, I hope nothing bad, probably fuel pressure or timing

[@kevinmarchini5272]

Called break-in

[@markmccarty9793]

Looked like it was lean as fast as the headers started glowing! I watch alot of these videos and never saw that! Why not start with a 460? Another 50-60hp.

[@coupe545]

That was part of the run in cycle. Couldn't go 460 as couldn't get a forged crank to suit the Ford journal Carillo rods.

[@markmccarty9793]

@@coupe545 it's impressive, I respect that. Though bought a 460 with air cobrajet heads for my 94F150 flareside. My father gave it to me. Money talks tho, got a boatload of Windsor stuff, heads, 2 blocks and ones a roller,intake,pistons already on the rods! Tci c4, that'll be the weak like if I get over the 100 powershot! And the weight advantage! Just for causing anyway!!

[@raginroadrunner]

Ford should have stuck with this engine.

[@raginroadrunner]

Is that all???

[@ronsmith7739]

That header on the left side looks real screwed up. Needs to have a straight line header like Mickey Thomson or Richard Petty did via lakester style header. Should be 800 plus HP !!!

[@coupe545]

Is what it is, only way it will fit in street car it was made for.

[@kidsteach938]

I guessed 750 hp at 7500 rpm...but I think 750 at 7150 is possible.

What are you talking about those are symmetrical port Ford John Kaase heads kinda like what GM did with the Ls 3 decades after Windsor, Cleveland and 385 series big block Ford 429-460 GM finally did away with siamese ports when the LS came out the 8100 Vortec 496 Chevy truck engine pretty much has 385 series Ford heads on it symmetrical ports on a factory BBC hmmm
