Thread: 500 horse 500 foot pound torque 327?

Tweet

Hey, i am a new member and i am planning on building a 327 over the next year or so. I was wondering what kind of work i would have to do to build it street legal, and with about 500 pound foot torque. i want to do this with a 327 because it is stock for the 66 el camino, and i would perfer not to have to build a 396 to get the 500/500 power. If any one knows specifics on how to do this, and could possibly give me an idea on what different parts i would need to do this would be greatly appreciated. and if there is no way to build a street legal 327 with this kind of power then i am curious what kind of power i could expect. thanks.

Chevy made a 327 with 375 HP. I suppose you could get 500 hp and 500 lbs-ft. Got about $20 grand?

Pro-built racing short block
Brodix full-boat racing heads
13:1 Compression
Racing fuel

Some of these guys did it - although most were 350 CID.

You'll probably need to put a 327 on some boost to make 500ftlb torque.

I was thinking along those lines. The short stroke 327 is gonna have to spin upwards of 7800 to make those numbers and the torque curve is gonna be real peaky.

Be a neat motor though.

[B]Hey, i am a new member and i am planning on building a 327 over the next year or so . I want 500/500 power.

Lets see, New member, Welcome to the club. We are glad to have You here and look forward to talking to You in the future. The el camino sounds like a nice ride.

Now ! Wake up, This dream is nice but not too realistic . A 327--350hp makes a real nice street motor that You can enjoy.
The most advertized torque that a 327 ever had was 360@3600 rpm. That was with 11 to 1 compression and good gas.

You would enjoy the 350 or so hp. in your el camino on the street. Anything more you will pay the price in more ways than one.

Just my opinion, not worth to much, Its your money, Your truck, do as you wish. Good Luck and Again WELCOME!

Riverhorse,

Very well put, right on the money!

Welcome from me too

I agree with 'Horse and Henry, 500 hp small blocks are very expensive and would not be very streetable. A small block with 500 horse a a very peaky torque band would need a 5 speed with tall rear end gears and 7500 RPM shifts to make it pull decent. Not real practical in a street application. But hey, it's your car!!

Anyway, welcome to CHR.

Hey, i made a post yesterday about this and today i can't find it so i'll post again. i am wanting to build a 327 for a 66 el camino but i can't find the info i need to buld it with the power i want. I want it to push about 500 horse with 500 pound foot torque. If this isn't possible PEASE tell me, but if you do know how this could be possible and the car still be street legal i would really like some help. this will be my first engine build so i will probably have a lot of question over the next few months. thanks for all the help.

i can tell you what most people said yesterday. to do this would cost to much and wouldnt make a good street motor. i agree

IF you could build a "street" 327 with 500 ponies for XX dollars, why wouldnt you build a "street" 383 with 500++ ponies for the same XX dollars? Block prep costs the same, cranks cost about the same, pistons the same, heads the same, etc, etc.

IF you arent building for some class rule that limits cubic inches, why not go big? Especially since getting 500 horsepower will require non-stock components.

Just curious are you looking for a good quarter mile time or just 500 horse and torque???

street legal shouldnt be the question. The question should be streetable. I would say 500 streetable HP from a 327 would be pretty tough normally aspirated.
But than, whats the definition of streetable ? are we talkin something to just do a little local cruising between valve spring changes , or something that you can take just about anywhere reliably ? or something somewhere in between ?

build a solid bottom end and go for the 350 hp and drive every day. if 500hp is the goal just hook up a 150 shot of juice to wake it up

---I went back and read both threads again. At least 8 of us have either questioned your judgement ot tried to stear you down a more reasonable path. We have and I have vowed to try to be nice and helpful to new members. You are making it difficult. I guess You will keep trying until you hear what you want to hear.

Do you have the money and the tallent to do all the things that would be necessary to handle 500 hp? It takes a real good suspension, good brakes ,good tires and wheels,headers and good exhaust,good transmission,good converter, good rear end,good cooling,good distributor ,good wiring ,good heads, goodcam,good valves,good intake and carburator ,etc.etc.etc. How much of this do you have now???

Forrest Gump had a real good saying. I'll let You decide what it was.

Be Nice ,Gene ,BE Nice And You have a great day,Too!

This is doable Mo, if you have the money I'll help you with your combo- but first your going to need some special tools for this.
You'll need a small grinder simular to - but NOT a dremel- that has a top speed of 13,000 rpm, a degree wheel & dial indicator, a set of gram scales (ditgital), a full set of mikes. These are just enough to get you started, after you have these and 500 dollars extra in cash for the machine shop, let me know & we'll procede.
