You are right Jester,I think Dyno tuning is a great tool for getting the most H.P. out of an engine.
Sure beats running up n down the road to adjust stuff.
The number at the rear wheels is like you say always lower than the FWheel number.
Wow I dont no how many Flywheel H.P. would be needed to put 600 to the ground probably well over a 1000.
Some of you guys r lucky to live in a place where there is dynos available,
I moved here from Miami n its culture shock for Hotrodding

Check the collages close to you if they have automotive classes they may have a dyno (They do at some collages around here) you can schedule your car for a class and they will dyno it free (collages dont charge labor) and if you check with the instructors you can sometimes bring your own parts for a dyno tune. Collages also do repair work on public cars no charge but they can not buy you parts or supply them !!

The hot roders around here that know about it go to a school about 40 miles away and are very happy when they leave

To get 600 hp to the ground depends on the paresitic load on the eng. Water pump, trans., drive shaft, universals, fluids,
ring & pinion, torque converter, disc brake or drum drag, axle bearing drag, fan, aircond., alternator,power steering, the weight of the rims, and much more, any thing that puts any kind of load on that eng. is reducing total horse power and torque away from whats needed to propel that car !! The other factors are many like oxygen in the air, fuel, barometric press., plug wire resistance per foot, spark plug resistance, humidity, temperature of cooling system ( too cold lose hp too hot lose hp) and on and on!!! Even the bends in exhaust systems reduces hp & tq

Any thing you can do to get rid of these parasites will free up horse power !! I did A 440 road runner a couple of months ago ( an 11's in the 1/4 car) he had Blue max 800 ohm wires New out of the box(The brand doesnt mater really) And New autolite resister plugs! After the dyno run We changed to accel copper core plug wires and autolite copper core plugs same heat range And picked up 10 hp at the same rpm and load, changed back and lost 10 hp put accel & autlites back on gained 11! Did this 4 times and still showed the same average gain of about 9 hp! Then he was worried about radio noise but his radio played fine, He says he can really feel the difference on acceleration, the only complaints are from his neighbors ,because their home tvs and radios act up when he runs his car (the radio in his car plays fine)!! Now thats cheep hp!! Now think over this, people bore their 350 eng .030 over + buy pistons and rings and gain 5 cu in. and pay big money! If they get 1 hp per cu. in. ( 1 hp per c.i. is very good) and they spent over 300 bucks For 5 hp. Compare that to 10 hp for about 70 bucks!!

Now Ill try to head off arguments I dont favor 440s, I dont favor accel products or autolite, ( I actually like champion and mallory) Im not telling any one to do this, Im not saying not to bore a block ( boring is actually needed to repair cylinders Or needed for some planed builds ) Im not saying everyone will get 10 hp (a 6 cylinder grandmothers cutlass isnt going to get these gains), Im not saying a complete eng bore ,pistons,rings & bearings cost 300 bucks.And I dont dislike a 6 cyl. cutlass' My wifes a grandmother and I bought her one! I dont need to hear about it effecting electronics or fuel injection Ive done this to both injected and electronics, and Im not saying it wont effect all injected or electronics on all cars every where!

Ive got a chart I made on other tests Ive done on different brands and Ohm ratings on fords , Chryslers, chevys ,Etc I have ohm ratings and hp gains wrote down. If I can find it Ill post it! The brand names didnt really make a differents They all performed pretty much the same if they had the same ohm rating, The less ohms per foot and the shorter the wires the more hp was gained.
I retired 4 weeks ago and closed my shop, I put all my equipment in my 3 car garage!!! Its so full all our cars are parked out side under the car ports and some of my equipment is in my back den The only paper work I separated is what I need for taxes So it may take me a while to find some of my test charts their packed with All my other papers in boxes they date back 30 years. But there must be something on line about resistance and hp thats not biased ( like a co. testing its own products)

I built a similar engine for my nova

I used the article cobalt posted for my Nova

However I ended up running 8 to1 compression In order to run 87 octane. I get 21 m pg with an overdrive transmission. Naturally aspirated I run 13 flat in the quarter mile. With a 75 horsepower shot I run consistent 12.3 in a quarter mile.

Nice work 12.3 is a very respectable time

Im very happy with the results. It was a blast on the Hot Rod Power Tour. It didn't cost me a fortune in fuel and I was able to cruise 70mph. I also enjoy participating in the real street class(7.50 and slower index w/ street tires) at the local track during the street racing events. I run a consistent 7.58 in the 1/8 mile if I get it to hook

I also, have based my engine build on that series of articles (it helped me choose a cam)
but I was a little farther into the head and cam upgrades that they did in later articles, with the same motor.

so do you have the peanut-ports?
and did you use the XE268H cam?

the reason I ask, is I am curious about the lower CR

Yes, If you read my thread it states that I used the peanut port heads with a Comp Cams xs256s camshaft. I ported and polished the heads with bulk of my concentration on the exhaust side. I used stock valve size, upgraded springs, and the matching comp cams stamped steel roller tipped rockers with 1 piece push rods.

sorry, but what thread?
do you have engine build thread?
or photo journal?

are the XS the same as the XE but soild lifter?

that cam is 2 sizes smaller than the article used
so i am sure that helped with your choice to use lower CR

very good, missed that i guess

I asked about the cam vs. CR because I am trying to see what I can get away with for my build, for the CR

but you are way lower on the cam then I am, I have the XE 274 H
thats is why I asked if you had the XE 268 it would have been close
its no wonder your CR works well, with the cam you have

I'm a motorcycle guy, (not HD, Imports)
As I don;t come from 'automotive' I don't have preconceived idea's about what is 'right'
454 is about 7.6 litres, 500bhp is about 65bhp/litre, not a particularly good output in my opinion, 85 is reasonable, 100 or more is good (around 150~175bhp/L is 'normal' for motorcycles I work on, even 1970's low rpm make about 90bhp/L at the wheel with stock cams and carbs)
I like small ports with thick walls, you can shape them where they need to be for best flow without being oversize and losing driveability
Personally, I would buy a cheap electric die grinder and router speed controller (Harbor Freight tools, probably less than $75?)
plus some GOOD carbide burrs(expensive, about $30.00 each) and open ports closer to 'stock' (even though rectangular ports are not so good for flow)
Do a bunch of reading/searching (articles by David Vizard are always good)
Stock BBC heads respond well to only minor clean up, I see no reason why the small port heads wouldn't do the same?
It all depends if you have more time or more money, quickest thing to do would be bolt on some decent heads, cheapest thing to do is DIY

Ditch the peanut ports and go for some closed chamber heads and you can get away with that cam and factory flat top pistons. Otherwise you will need some domes and serious work on the peanut ports. That will save you a couple hundred dollars.

Furthermore, I spent some of my time concentrating on the balance of the engine. I put my longest rod with my shortest piston and etc; I also balanced all the piston/rod assemblies within 8 grams of each other. Not an over the top balance, but enough to give me a snappy throttle response and some assurance when I rev to 5500 with nitrous on factory rods. The only other upgrade I recommend is ARP bolts. I ran the small cam and the peanut ports just because it fit with my engine design and budget I was building an engine for torque; not horsepower. Like the previous poster said;"I have more time than money"

I dont have the peanuts
I have some 781s that have been cut for larger valves

I was asking how your 8:1 comp. works with the XE 268 cam that was used in the build, in the magazine article

but you used a lot smaller cam
