What kinda HP?

[Anonymous]

1965 Ford Fairlane
200 6 w\ 1979 head milled .060
Victor Head Gasket
Duraspark Dizzy with HEI ignition module
Holley/ Weber 5200
Nitrous 75hp shot.
What kinda HP/ et should I be able to get with this combo?

Is the carb fitted directly to the head, or through an adapter? Stock camshaft still? I'd say 95-105HP off the bottle and maybe 145-155HP on the bottle.

adapter. Is the 75hp shot not really good for 75hp? False advertising.

Kinda. On a 350 horse 350 Chev, a 75 shot is probably worth 75HP...

You are probably looking at low 19's w/out nitrous, and high 16's with it.

Obviously the NOS will give you a boost. Without the NOS if you do nothing with the head anything else you do will be minimal gains. The head is where horsepower is gained or lost. The log style heads just don't flow lots of air fuel mixture. Throwing on more carb and cam won't do much if you don't increase the breathing. Change the head go with larger valves and port if possible. Then throw in the aftermarket cam, ignition etc... Otherwise there isn't anything you can do to get staggering increase in power. Everything starts with the head.

so what et's does a totally stock 3 speed manual 200 have???

Let's just say, if it starts off the line at 0900, bring a cut lunch.

In published road tests from the sixties and seventies, stock six cylinder Mustangs and Mavericks ran the 1/4 in approximately 19- 20 seconds at about 67-68 mph.

The local "official unofficial" V8 Falcons (64/65/66) ran a 260 or 289 with 4-speed. They clocked "low 16s" according to my reference. I can't imagine a Mustang being too different.

That being so, I would imagine 19-something to be a good time for a stock six-potter 200.

yea thanks for the reply. it is really slow. lol. i guess sooner or later thats a good enough excuse to rebuild it. so about how much nitrous could a stock motor take. im thinking no more than a 50 shot? not that i would do it, because i would rebuild it before that. the nice thing about them being slow is the good gas mileage. i can coax anywhere from 20~22 out of it. and its slow but you can still burn a little bit of rubber.

I'd guess that on an engine in good shape, a 100hp shot would be tolerable. On a tired old worn-out engine you'd be pushing your luck.

isn`t that a bit much for a stock cast crank and cast pistons :

On any other engine but a Ford I6, a 100 hp shot would take it out! Good thing is, nitrous is more worried by thermal stress rather than sharp loads on the rods. It's very unlikely a six-potter with standard cam would rev beyond 5000 rpm, and the piston speed even at 5500 rpm is lower than, say, a 327, 350, 351 V8 and way, way below a 225 Chrysler. Cast rods and slugs shouldn't cause a problem!

Only issue I can see is lean conditions for the Excess Fuel Factor. The outer rear cylinder may find going tough because it may not get enough rich fuel to go with the oxygen -liberating nitrous. The front cylinder is over-cooled, so a lean-out shouldn't cause a problem. At the end of the day, number 6 cylinder is a long way from the gasoline scource. Nitrous must have extra cooling gasoline to stop the combustion chamber becoming an expensive gas-axe!

Port water or methanol injection may be another option to ensure that never happens, but I'm gliding off into Weird Six Science here....again!!!

The stock engine is so understressed that another 100hp is not really a problem. With stock rods and pistons, an engine could be built to the 200hp level. The real killer is rpm. If you attempted to rev it past 6000 yoou go past what the stock rod bolts and pistons can safely handle. That's when things start to go bad.

To do so consistently you'll need good rod bolts, bearings, and careful attention to assembly and clearances. Drop a 100 shot on a worn out old engine, and you may get to do that very soon!

I ran 60hp on my 200. It was killer off the line, even yanked the wheels when it hooked good, but top end really didn't pull hard, probably due to stock cam, and carb. You won't get any extra RPM from nitrous, it just gets there quicker. The biggest thing to remember is stay conservative.

so how much horse power could you get out of a 79 200 with a isky 280 cam, 2 32/36 holley webers, .060 milled head, flat top pistons, with stock type gasket, stock rocker ratio, good bearings,godd coil, and forged connecting rods with arp bolts?

Enough to get arrested!!!!:nono: :rolflmao: :shockin:



The rule is half the existing maximum power can be added. But thats for modern vehicles. Older I6's like ours can handle more!

Your machine could have up to 145 real SAE net horses at the flywheel...the 32/36 is limited to 145 with its 225 cfm at 1.5 inches of mercury carby flow, but a nitrous engine doesn't need extra carburation, because the gas liberates oxygen. The cam is perfect. I'd plug in a 75hp kit , and expect it to behave like a 5.0 HO Mustang.

The cops are the least of your worries...imagine the terror caused when a ride like yours has its suspenders dumped after blowing the home boys into the weeds.

Thats nice hear

:idea: Where could i get a 75hp kit for a good price?
