I'm suggesting he keeps the "R"'s down and capitalizes on low end torque....................


This craze to HP on street driven vehicles just doesn't make much sense.All of us got wholesaled on HP yrs ago and now bad habits die hard. Even some of the best bracket cars are torque beasts and not so much HP animals. The first 60'/330' matters.

If your going to tell me a HP rating at 6,000 or 6,500 on the same sentence as talking about a vehicle mostly driven on the street,I gotta stop and clean off my keyboard and screen from the coffee I coughed up.It's a whole lotta so what??. Count the number of times you actually used that on the street. I am saying for street light racing what really matters is torque. Well torque and getting the car to hook.

And if you going beyond 65 to 70(that's pushing it too),you need to have someone take you behind the shed to explain in street light racing that ant cool.

Sorry guys,but when I see a torque peak at 4,500 and HP curves at 6,000,it gets me into a bit of a rant.

Tailor build the intended use.We know how to do this. We can spend the money where it is most useful and enjoy the build.

Sounds like a truckload of common sense to me.

I some what agree with 1gary,,,

In order to compete with a guy that has a 2300 pound civic with an 8,000 rpm 1.8 liter v-tec I have to have both torque and HP.Most torque monsters shred the tires while getting in their own way.I have a 3200 pound car so I need over 400 HP to be even with a near stock v-tec in a civic. I feel sorry for people that are trying to compete with 30 year old technology. We need engines that can rev freely to 6,000 plus to beat up the imports.

drive a new Camaro/Mustang?Challenger,,,great power,but they all are 2 ton tanks.
even the new corvette,close to 3700 pounds,OMG!!!
Shelbey was working on a cobra that weighed 2200 pounds and had 600 HP,that guy was a genius/crazy

even 195cc heads seem a tad small for a 500hp+ 383
my 221cc heads on 355 seem to work real well.. up till 7500

A civic is definitely lighter than the new muscle cars but I don't see where you need 400hp to compete with a stock si? mustang v6 does 0-60 in 5.1 and can run the quarter in 13.7. It also weighs 3500 lbs. An Si is a fair amount slower than that.

I agree, I dont want HP peaking at 6000. What I dont understand is how do you come up with a setup where HP peaks say at around 4500 and TQ does the same. I mean how would you find out without building a setup and putting on the dyno.

the v-tec 1.8 is an engine swap/stock 180 hp.usually tuned to 225 plus with bolt ons
0-30 faster than most of what we have,,0-60 similar to a high 12 low 13,they run 13s inthe 1/4

chev SS,there is supposed to be a gap in hp and torq
well tuned imports make more hp than torq

detuned(or stock) north american make more torque than HP and peak at a low RPM
shorten the cam timing to lower the peak rpm of horse power

If I want low end HP and TQ I need to find a cam thats rated from idle and up correct, but also needs to go with my cylinder heads right???????????????? Most big cams start at 2500 - 3000rpm

If you want low end grunt,low RPM engine then consider a stroker,or an oldsmobile engine.determine what power and torque you need/want and figure out what best matches your desire? With every goal you need to include budget and perhaps in your particular case,exact expectations of the engine and exact application

It's going to be a 383 stroker. I want 350-375 HP and 425-450 ft lb TQ. That is a fare realistic number for a vortec 383. This is a truck motor. A 1994 c1500 to be exact. I should not need a huge cam for this but considering I'm not to good with understanding which cams are better than others or which ones are made for torque or made for power I'm not real sure on which way to go. I have got it down to a few cams. Look at the specs and tell me what u think.

Lift: .500/.486.
Duration: 295/313
Rpm: 2500 to 5500

And

Lift:498/483
Duration:279/297
Rpm: 1800 to 5600

Also

Lift:.488/.510
Duration:308/318
Rpm:1500 to 6500

I'm thinking I could probably go with a little more lift

with a 383 I would go with a good set of heads,a mild cam and do some gear work everyones talking about torque and hp. A cammed 383 with the right rear gear you wouldnt have to worry about a 1.8 civic.Its just trial and error till you find what ur looking for.With good heads,mild cam you should have no problem reaching ur 350hp goal.It takes more then hp and a nice torque curve to go fast. 230/236 .565/.570.....nice cam in 383 with the right set up you can go past 350 horse.Its a nice dual pattern cam but really dont know what ur running so cant really spec a cam assuming ur going to build a street car or truck milds the way to go.

Actually it would be a 377 as this will not be bored. There is no point cause the cylinder walls are beautiful. Not that this matters I just wanted to clarify that



Above I have a parts list above with what I wanted. 195cc AFR heads. Don't pay attention to the cam specs above. I was thinking about a different engine. I'll be going with a roller cam and retro lifters. Here's the roller cam I want.
The setup was dynoed at 500 hp.

You gotta be careful with those Honda's.. There's some here in town that will Spank the average V-8 Street car. Those Turbo's can be deadly
