Oh Boy, First thread- How much power

[Gordon Levy]

Maybe we can use this thread to give hp estimates for different packages. What do you think?

[Kyle Stewart]

1966, 289 block rebuild. Stock everything but need new pistons. Any suggestions for a "run around town" 67 fairlane?

[Gordon Levy]

225-250 depending on cam and carb stock.
The 289 is a great engine. It can produce 350hp pretty easily with the right parts.
Good rebuild with flat top forged piston
Edelbrock Performer RPM or like heads
Proper hydraulic flat tappet cam
Performer RPM ontake
Holley 670 street avenger carb
This will give you a real 325-350hp and be daily driver realiable.

[turbodon]

408, Victor Jr Heads & intake, Holley HP 750, Roller lifters/rockers (1.6), 10.1 compression, cam 224/232 @50 with 542/563 lift.

[bill fuss]

This sounds like fun.

[bill fuss]

Im putting together a 351w,stock/printed short block/retrofit hyd.roller 224/232 .556/.566 w 1.6 rockers,twisted wedge heads w bowl/port work, rpm manifold, 750 edelbrock carb. Whats your opinion on using a hv oil pump. Ive got .0018/.0021 bearing clearance. Forgot to say pistons hyper. flat top/12cc reliefs.

[Joe R]

392 with 15cc dish(9.7 to 1), AFR 185's, Vic junior, balanced,4150 750 holley, CC XE284H(.540/.541 240/246@.050), CC pro-mag Roller rockers. How much HP??

[Gordon Levy]

Don, You will be really close to 480/480
Mill, don't use a HV pump. 1 out of 5 will distroy the engine. You engine will be right around 380-400hp.
Joe, 420-450 with a proper tune.

[Jack ffr1846]

Oh, I like this:

Explorer 302 (has GT40...not p heads and explorer upper/lower)
Mustang throttle body and mass air
E303 cam.

[Gordon Levy]

Jack, 270-280

[Mike D]

Stock 5.0 lower end, E-cam, Twisted Wedge heads, Edlebrock Performer 5.0 intake, 70mm MAF and TB, 19lb injectors.

500/500 right?

[Gordon Levy]

Mike, About 300. 275 if you have a stock cam.

[Mike D]

Definitely some cam in there, is that rear wheel or crank you're estimating? After it's on the road I'll probably have a dyno/tune done, be interesting to see the numbers but I can already tell it's gonna be fun no matter what they are.

[PSB]

I'm in!

408W
11:1 Compression ratio
AFR 185 heads
- Multi-angle valve job from Total Engine Airflow
- 65 cc chambers (I had them opened up to lower compression)
Scorpion 1.6:1 roller rockers
Trick Flow 351W intake
75 mm TB and MAF
36lb injectors
Levy Racing road race oil pan (good for at least 50hp right )
Comp Cams hydraulic roller cam - Specs:



Pete

[Greytracer]

OK guess this one:

410W forged crank/rods, 4" stroke and 4.040 bore, AFR 225 heads, flat top pistons, 12.5:1 CR, 1 7/8" primary headers, Solid Roller w/ Comp 286R 248/254 .615" lift, Wayne's stacks port matched with AEM computer, coil per plug, crank triggered, Gordon's oil pan.

Mark

[Brick4brains]

1986 302 block decked, bored .030 over, stock crank, Eagle rods, forged flat tops, FMS X cam, 1.6 rockers, AFR 185s, Edelbrock Air Gap intake, Holley 750 double pumper w/choke horn milled off, all MSD. Currently puttint 313 HP to the ground.

Changing to custom ground Comp Cam somewhere in the 236/240 .555/.576 range, Victor Jr. intake. Also going with a valve spring upgrade.

Drew

[Gordon Levy]

I need to say first is most of my guesses are just that based on what we have done with very simular engines in the past. I do have engine programs I can run this up on but it would take a couple of hours for each one. The numbers I give is estimated flywheel hp.
PSB, around 525hp/500 torque- You will pick up over 40hp if you went to a carb.
2370, I think your engine is capable of over 600hp with a carb. I believe the injection system is going to cost you some hp. Do some research on independent runner intakes and you will see what I mean.
Brick, 313 at the rears is equal to about 370 at the flywheel. Going to a different cam and a Victor Jr intake is going to help a lot. Maybe another 25-30hp or so. I also think you should use a 650 carb instead of the 750. It may cost you 5hp at the top but your throdle response will go way up.

[Larry N. Johnson]

Gordon,
As you know, Old 3850 has a bone stock 95 Cobra engine. Cobra upper and lower, GT40 iron heads, Crane rockers, 24 lb injetors. No smog stuff at all. It goes like crazy...any idea what HP is has? Any idea if the cam is different than a std HO engine?

Also, I have to shift 5800 or it cuts out. Would that be valve springs too weak or the X3Z computer holding back?

Thanks!

[David Borden]

Larry, im going to guess around 260 hp.

Gordon has been pretty right on with his estimates based on what I have come across.

David

[Useless]

Need some tech.Gordon and I have talked about this before but know I need alittle more.What I need is a drawing or diagram of Ford flat top pistons with larger valve reliefs in them with depth for 2.02 valves and big cam . I have mocked the engine up and showed the machine shop the puddy but they donot want the work or do not understand it. Ibelieve if it was a SBC they would maybe understand thanks ahead

[Useless]

Sorry maybe I should have started a new tread

[Grembler2]

Ok, I got one for ya Gordon,
How about the 331 Levy Special that you are building for me for my Coupe?

Eric

[Gordon Levy]

Useless, Find another machine shop. Any machinist worth his salt can fly cut the pistons for you. The other option is to buy a set of pistons that are designed for you engine set up. Please feel free to call me if you have any questions.
Larry, I agree with David on about 260.
Eric, It will be a very real 450 and can be tuned for more.

[BillHeffelfinger]

Gordon: Ford Motor Co. crate engine, edelbrock intake and carb. MSD6 ignition system. (what a great thread).

[Gordon Levy]

Bush, It depends on which engine you have. Ford has been pretty close with their numbers so I believe you will be close to what they advertize.

[dv/dt]

Hi Gorden,
How about a refreshed 302, 58cc AFR 165's, QR Mass-Flo with a Spyder II intake, F303 cam, 30 lb injectors, 4-into-4's, no smog.

Cheers, Rod

[Scott Shumaker]

Gordon try this one:

372w, 9.5 to 1, Vic jr heads(box stock), Offenhauser dual plane, 750 Mighty Demon, 1.6 roller rockers, hyd flat lifters, Comp Cam specs .532in .545ex durations 234in 246ex at .050 112 lobe sep, Paxton 1200 supercharger pushing around 7psi

[Gordon Levy]

dv, about 325-340
Scott, I would really need to run it up on the computer because of the blower, but as a guess I would say around 550. Your cam has a little to much overlap for the blower to be at full efficantcy. I think you would make better power with a little less duration and a 114 degree center.

[BS]

Well, maybe I can save buying parts twice if you can give me an idea where I'll be with this combo and an alternate choice.

393 Windsor, TFS Stage 1 cam, GT40P heads mild port and gasket matched, 20CC dish pistons 9.7:1 CR, Weiand Stealth manifold, Holley or Edelbrock 750, Ford Shorty headers into J-pipes. Underdrive pulleys, with serpentine set-up. Ford retrofit roller lifters and 1.6 roller rockers.

How much would I gain with a TFS Stage 2 cam and a different intake? Any other cheap ways to gain a bit of HP?

Thanks,
Bob

[Gordon Levy]

On a 393, the heads and exhaust you are proposing is going to cost you a lot of potential power. You really need much better heads and full length enhaust.
