My new 351w Is it worthy ?

Stangninjak · Feb 6, 2006

These are the specs for my new 351 I am putting in my 65 coupe. After my old block got grinded pieces through-out, I went to this setup. This is from a 94 base block.

Boil, Bored & Honed 0.40 over bore
Cast Iron Custom Ground Crank Assembled New Clevite 77 Rod And Main Bearings
A Set Of I-Beam Ford Factory Forged Connecting Rods that are checked for straightness and re-balanced

High Performance Moly Rings
A Three Piece Cloyes Street Racer Double Roller High Performance Timing Set

Head Specs:
Trick Flow's Twisted Wedge Aluminum Cylinder Heads (Pt# TFS-51400002)
61cc Combustion Chamber
2.02 Intake Valves
1.60 Exhaust Valves
High Rate Valve Springs, 7 Degree Locks, & Manganese Bronze Guides
Trick Flow 1.6 Ratio Roller Rocker Arms
Assembled with ARP Hex Head Chromemoly Steel 170,000psi High Performance Head Bolts

Cam Specs:
Brand New Trick Flow Track Heat Camshaft (Pt# TFS-51402000)
Lift: .499 in. intake / .510 in. exhaust
Duration: .275 intake / .279 exhaust
Lobe Separation: 112 Degrees
Power Range: 2,000 to 5,500 rpm's
Brand New Ford Motorsport Racing Hydraulic Roller Lifters (Pt# FMS-M-6500-R302)

Carb:
Elderbrok 1406 600cfm with electric choke

Intake:
Elderbrok 351w Perfomer Intake. Port and polished.

Headers:
Headman Long Tubes. 1 15/8.

basically I am using the parts on top that I had already, and replacing the block with the heads and cam, lifters ect. heh I had the block painted yellow, to match my car. My engine bay is black. This is being paired with a 4spd Top loader, and I have a 9inch rear.

So o knowing members of this forum, will she be worthy ?

The carb is too small, and that intake does not flow well enough. Those parts will bottleneck your build.

Stangninjak · Feb 6, 2006

So maybe a RPM Preformer 351 Air gap ? Hood clearence can become a issue with the vic jr.

Carb wise, which carb ?

Holley 700 or 750

I am running a 351w with almost the exact setup. Performer intake, aluminum heads(63cc)Holley SystemaxIIs, Ford Motorsports roller lifters, the track heat stage 1 roller cam TFS-51402000, 1 5/8 shorties, 650 Speed Demon, T-5, and was 3.50 posi but now 3.73s. I had way more power than the stock 302. I was getting 18mpg on the hiway. I think the intake is fine for a street and strip car. I barely clear the hood and had to modify the air cleaner to do so. The heads you have will give you more compression than me. The stage 1 cam is small, but perfect for a 302 based engine. I just bought a stage 2 TFS-51402001 for install soon. If you're digging into the block, going .040, why don't you just stroke it?

I came back to add- Opentracker runs a 650 Demon on his track car. I based my decision to run the 650 Demon off Opentracker's recommendation. A holley 650 double pumper should be fine(4777). Just tune it.

How much power did you make with your setup ? I may try a stroke kit, but I was going to see how this went. This is a street/strip car btw..def more steet than strip. I just do not want no dam honda's screwing with me

Yes the carb is too small, and that intake is limiting you bigtime, will create a huge bottleneck up top. Go with a Weiand Stealth Intake it will meet your needs exactly.

Stangninjak · Feb 7, 2006

Ok. So my next question is..

Will these intakes fit underneath my hood ? I have a 65 coupe with the stock hood, and a scoop in it. I also have the ford racing oval air filter <black> one. I would like a Air gap, or this stealth I have heard about, but I am worried if it will fit under the hood.

Anyone running this type of setup with this type of hood ? Does it fit ?

5.0ina66 · Feb 7, 2006

They'll both fit fine, especially since you have a scoop. I'd go for the Stealth as its a little shorter than the AirGap and just as good IMO and cheaper. Edit: with a W in a 65 you'll NEED the extra space that the stealth leaves you. That intake is fairly tight with a 302.

HMM · Feb 7, 2006

What intake would you suggest if hood clearance wasn't an issue? RPM Performer 351 Air gap? I'm going to be building mine soon so I'm trying to read and learn as much as possible. Sad to say, most of my knowledge has been with rotaries...

67GTCOUPE · Feb 7, 2006

Air gap is as high as Vic Jr....so no good for hood clearing!

Put a 750 holley, and stealth or rpm intake, and you will have a wicked screamer!!!!!!!!!!!!!!!!!!!!! That tiny cam works WONDERFULLY in a mild 351w on the street!

Make certain you have your car tuned....those pistons will take not much detonation abuse!

WTF? Detonation is bad, but I don't see whats so fragile about the pistons? KBs ARE the best on the market.

I am not trying to be a dick, but KB pistons are NO WHERE NEAR the best.

If they are not FORGED........then like all other casy/hyper pistons, they do not take much detonation before shattering, breaking.

Hence, my comment.

Oh *****..what is the best then? I was all ready to dump my TRW forged pistons in favor of KBs because I don't really need forged. If KBs are no good, then what is?

Stangninjak · Feb 8, 2006

Good Info guys Keep it comming. I am going to go with a Stealth or a RPM then...I thought about porting some more, but the prices I was getting I might as well get a new intake !

The KB's I have are the Hyper ones, supposed to be 30% stronger... or at least that was what I was told they were, and I will def get the car tuned after I get it all together. Hopefully my block will arrive this weekend. I will keep the carb I have for now, but knowing I can go beefier will be geat. I may update then. I still want to get decent gas mileage out of this thing But knowing me, I will be slapping a bigger carb on top a lot sooner than later..heh I should just get it out of the way now..

Why wouldn't you need forged? You already have the TRW's?

Why do you want the best but not forged???? Forged are the best for any type of power production.

TRW forged would handle much more abuse than the KB hypers.

If you want to spend lots of money then look into JE, Mahle

It'll be a purely NA street motor...I can always build a turbo motor later I was always under the impression that hyper pistons were better for an NA street motor because their size stays more constant when they're heated, as compared to forged units. I cannot afford Mahle or JE

Stangninjak · Feb 8, 2006

I have a question about a Intake..I have been offered a Torker II (Edelbrock) for my 351. Its been slighty ported, and the guy wants 150. Is the Torker II a decent intake ? Is it too much for my setup ? Not enough ?? I am basically going street/strip..more street than strip, but I still want to Feel it..if you know what I mean..Should I try this ? Or just get a RPM or Stealth ??

Most of what you read pertains to max effort engines where 1/10 of second makes a big difference. If this is for a street car you will most likely never notice the difference.

If you already have forged why would you spend any money to replace them with hypers?

Torker II is probably a tad bit much for your application. It will move the power band up in the rpm.

My new 351w Is it worthy ?
