- 1979 F150 with a 351w
351w with: gt40p heads, 4V QuickFuel Slayer 600 vs carb, Weiand Stealth Intake, Comp Cams Mutha Thumpr Cam (roller cam, part number 35 601 8), Summit Ready to Run Distributor, all backed by a C6 transmisson with a shift kit and 2500 stall converter.
Exhaust: Shorty Mac headers (gt40p specific), true dual pipes (no crossover, x, or h) into thrush welded mufflers, all 2.5" pipe.
Nothing sounds like an idling 351w with a cam... Sounds like a truck from heaven.
In the video it was a 600 Quick Fuel Slayer VS. Since then its been fuel injected with a holley sniper and turbocharged.
@@dentsidemechanic1238 sound change much since the sniper install? I’m currently building a 351/ bored & stroked to 427ci on my channel. Going to use the sniper stealth.
@@dansgarage2010 I have another video with sniper installed. With the sniper and 5 speed I was able to get the idle higher in neutral so its not quite as lumpy but still sounds mean.

That is what a truck should sound like, nothing beats the sound of a cammed and carbureated v8
That sounds so good. I love them 351 Windsors
I love that idle man sounds sweat👍👍
sweet rig! im hoping to get myself a 79 ford soon, might've found an f100 with a 351C, so sick
music to my ears
Now that is what a truck should sound like
I bet the neighbors love the "hay choppin" lol
Dude, PERFECT idle
Hey! I have a nickname for it. Frankenstein! With the sheet metal body work and pop rivets showing. Lol! I love fords. And that thing sounds wicked.
We call it Rufus or Ole Sanford lol. But i dig Frankenstein!
love the 600rpm chop
Was thinking on LS swapping or 6.0 powerstroke swapping my f350 that has the 351... listening to this I’m getting it cammed as soon as possible!
You do you but I like ford in a ford. Hard to beat that ole cammed windsor though.
My Capri with a 408 sounds like this . And my 79 2wd Ford f1 long box too . That's got a 393 stroker in it and gear drive. 4-56 gear ratio on a spool c6 with manual reverse valve body. Should be interesting to hit the highway
Hombre, ése es el sonido de un Motor V8 Saludable..!! Perfecto
Gracias amigo
DUDE, headphones worked as a MF, awesome sound
Im building a 351 windsor 1994 roller cam block doing short tube headers edelbrock performer intake holley 650 carb ported stock heads what cam should i use to get a similar sound?
I used the comp cams mutha thumpr.
Any of the thumpr line of cams will give you a similar sound.
Lunati barebones is a pretty radical sounding cam.
E303, F303, X303 cam will give you a good lump.
Those are just the ones off the top of my head. RUclips search 351w cammed and you should see a lot of different cam options.
Just an fyi most of your lumpy cams have a high lift and you'll need a good valve train to support and also pay attention to the required compression ratio, rear, gearing and torque converter if applicable.
A lumpy cam without good supporting components make for tough tuning and a dog of an engine.
twin 351 boxer ... the diamond
I noticed you had an aftermarket rpm gauge. Would you recommend having one? I have a '77 and idk why you'd want one unless your really getting after it with a build.
I got one because it just helped with overall tuning and also have a manual shift kit in my c6. I like to know what rpms im shifting.
Is it absolutely needed, no. But i personally enjoy it functionally and aesthetically.
I have a holley sniper efi now and that had a tachometer built into it. But i personally like the look of a tach and i didnt want to sell it.
@@dentsidemechanic1238 sweet, thanks for the fast response. And that's a mean sounding truck haha
@@wyattm3667 no problem! And thanks
Can you just buy the shaft or do I have to buy the kit? I've got a 351w in my bronco and im wanting a cam but don't really know how to go about it, help would be greatly appreciated
You should buy the kit and then there will be extras youll need besides the kit i can give a small break down below:
With this camshaft, you'll definitely need new push rods and valve springs that handle the lift.
If you have a roller block you can potentially reuse your lifters and distributor gear.
If you have a flat tappet block youll need the linked retro-fit lifters and a distributor gear to match the gear on the camshaft.
Then as a suggestions (not absolutely needed but highly recommended) i would get a new high quality timing chain and high quality roller rockers.
You also have to look at the cam specs and match them to your current engine build. Alot of people just wanna throw a big lumpy cam in but if you dont have the supporting assessories (heads, intake, carb/efi, rear gearing, torque converter (if auto), or compression ratio) more times than not itll run like a turd and you'll be disappointed.
Is there a specific intake you have to run with the gt40p heads on a 351w? Or can I use the 351w intake I already have
Not to my knowledge. I used a weiand stealth intake for a 351w.
Multiple tests by several independents show the Performer or the Perf RPM to be superior to any Wiend.
In reality the early 351W heads with the fat spark plugs out perform the P heads.
Specifically the early W heads have 144 cc intakes compared to 124 with the same valves.
BUT the old heads do not have hard seats.
Rocker cams always love heavy intake pushes.
Sounds mean!! 👍👍👍
Sounds good
Could I build a set of long tubes for the GT40P heads, or is it better to build a clevor? Putting a 351W stroker in my 76 F100
That question is kinda outta my wheel house. Im not sure what's easier building headers or modifying a Cleveland head to fit a windsor. Im not sure what flows better either. I'd pick the head that flows better and go from thre.
From what ive read most off the shelf longtubes fit gt40p heads and clear the spark plugs. The catch is nonody makes a longtube header to fit into a 73-79 ford truck that has a 351w swapped into it. Some say that the hedman longtubes for a 302 equipped 73-79 will work with a 351w buts its 50/50. Most of the time they clash with the frame or steering box.
@@dentsidemechanic1238 did you use 90 degree spark plug ends?
@@janeandjohndoe8458 i used msd plugs wires that can be bent in any orientation
What part of PA are you from? I'm in the pittsburgh area. Nice fox btw, I have a 91 GT hatch. Wish I could be a part of the LX notch master race though
Im from Gettysburg area. Unfortunately i ended up selling my notch for a harley and to fund my truck. Couldn't afford to have two project vehicles.
Why does this sound just like the Ferndale from My Summer Car? Really nice truck though, sounds awesome.
Where’d you get the cam from?
Bought it through Summit Racing.
did you have to notch the pistons?
No the stock style 351w pistons have huge dishes in them. This is an '89 block that was rebuilt to oem specs.
Wich motor is better the 351w or 360 fe?
It comes down to a lot of personal preferences. I'm my opinion the 351w is better because there's ton of modern aftermarket support for them.
Especially if you invest in a dart 351 block then your set to make 1000hp with the right set up.
But when if you're going for stock or a mild build its really whatever you prefer wrenching on.
that sound great!!!!! that cam its pug and play on the 351w?
You need to upgrade you valvetrain, change pushrod lengths, and change distributor gear.
Where in Pa are ya?
I wish I can do a 351w swap in my '99 Ranger with those mods you got in your 351w but I seriously want do a 302 swap out of Explorer lol
302's can get chopping pretty hard
@@dentsidemechanic1238 probably easier to find the 302 out of a '98 Explorer
I heard the engine mounts in the '99 Ranger just needs to be modified a little bit to fit the Explorer 302
What lifters/rockers?
Comp cams linked lifters and scorpion pedestal mount roller rockers.
Would recommend stud mount but i didn't want to pay the money to upgrade the gt40p heads.
DUDE!! With🎧is it THE shit
How much did this build cost you roughly?
The engine build was around $3500-$4000.
Fresh Shortblock 351w bored .030 over $1400
Top end (heads, cam, intake) $1450
Carb + small odds and ends - $500.
I had a used 351w but the rings were bad and had extreme blow by so instead of rebuilding the block I just bought a shortblock.
Could prolly save some money if you have a used block or build your own bottom end.
Sounds good but what can it do?
Made like 350hp to the tires (so 400ish engine hp?). Good cruiser not really set up to race. But still had enough ass to hold its own when needed.
Did you need a stall with that cam ?
I used a 2500 stall. I was told by a trusted friend any higher wouldnt pair well with a mostly street driven truck.
As of right now i also have stock 2.75 rear gears. Going to a 3.25 soon. Definitely definitely needs a steeper rear gear to make use of cam and stall.
What did you have to set the timing to
I believe 12 degrees advanced. I actually got rid of the carb and put a holley sniper on it im running 14* advanced and she sounds a lot more rowdy with the better air/fuel system.
Did you have to do any machining on the heads
No sir
The heads has a multi angle valve job done to them. (Helps performance but not required). Gt40p heads require specific valve springs. Alex's Parts sells valve springs that don't require machining to install.
Did u have to change the push rod length
Yes the stock nonroller push rod is 8.150" i believe and i had to get shorter push rod. Around 7.5".
No crossover is the best!
What size cam? Lift, duration
Advertised Intake Duration: 291
Advertised Exhaust Duration: 311
Intake Duration at .050 Inch Lift: 235
Exhaust Duration at .050 Inch Lift: 249
Intake Valve Lift: 0.522
Exhaust Valve Lift: 0.526
Lobe Separation: 107
Was it just a drop in cam
Had to get upgraded valve springs, upgraded to roller rockers, and remeasure for push rods. The cam and lifters go right in other wise.
Could I use gt40p heads on a 351w bored 60 over?
Ive got gt40ps on my .30 over 351w. Just two thing you gotta keep in mind. 1) gt40p heads have a 7/16" head bolt you'll need to have it drilled out for the 351w's 1/2" head bolt.
2) you'll have a hell of a time w/ headers. I ended up buying mac shorties that are specifically made for a gt40p heads. They are for a fox mustang.
@@dentsidemechanic1238 Thanks for the info.
Honestly you probably shouldn't even bother with a .60 over small block. The cylinder walls will be too thin and won't handle heat or vibration very well.
That sounds like the smaller cam. I have a 351w with the bmt cam and it’s way nastier.
Idk could be the heads, intake, or any number of things i can show you my cam card or box. Its definitely the big mutha thumpr.
Part# 35-601-8

I am wrong sir. This is a mutha thumper cam. Not a big mutha thumpr cam. Tis what it tis though. Thanks for pointing that out.
Tuber Coupe Jr still sounds good! I’m building a 351w with Brodix heads, 11:1 compression and the bmt cam.
lack of idle speed, compression, and timing can make a good cam sound lazy
Fucking badass, any specs? Did you change springs?
Yes i used alex's part's springs. They have gt40p specific springs where no machining is required.
And what specs would you like? Ask and I'll answer to the best of my knowledge.
Sounds good at idle, I watched a guy jerk a brand new one out of his 302 and put in a voodoo. He said it fell flat on his face compared to the voodoo. Idle ain't everything, I guess. All that durations great, until it's time to haul ass.....
Must've not had the right set up. This thing pulls like a freight train.
Sniper holley efi, manaul trans, and steeper rear gears made a world of difference for me.
4500 RPM YOUR GONNA NEED AT LEASE 6000 RPM TO GET POWER OUT OF THAT COMBO
Ran great. Now she's got a 5 speed and turbo. Pull like a freight train.
@@dentsidemechanic1238 right on
SOYNDS GOOD. TOO BAD that cam would have decreased the Torque on that engine.
Compared to what? Compared to the stock cam or the 275 deh cam it gained torque. Truck runs perfect what I wanted.
Mufflers are trash.
My mufflers or mufflers in general?
