yes it is a wonderful thread,i hope everyone can learn something from this,cheers
I've spent a little time on "REAL" dyno's also. Our dyno cell's are about as "real" as any in the country (you may still be able to find a picture of them on the Superflo web site). My 598 fell a little short of the 1000hp mark (and only pulled it to 6300rpm), but it is well within reach. Maybe not for the average weekend builder, but to say it isn't possible???
Hopefully you have some good reasons, and not just because you haven't been able to do it.

Definately NOT for someone who wants to enjoy their thousand horsepower engine without pulling the heads every 2 weekends.
Everyone is saying you need this and that and all this other big GM stuff..
Here is a oem block with nothing big about it.. 521 cui.. Single carb with Kaase 429 boss heads making 900hp.. No port work to the heads nor the intake... OUT of the box deal
Slap in A460 block 4.5 stroke 4.5 bore, port the heads and intake.. BANG 1,000 on pump gas.. All day long
It is amazing what you can do when someone says you can't do it. That said, this is a huge chunk of "mud pie", (Black Angus style) you're biting off......
You will eventually need the dyno, if not for tuning, then for verification of HP numbers. Very few builds are perfect right outa the box. Also remember dynos are different, as the Department of weights and measures does not monitor or calibrate them. Some of the numbers tossed around based on "pump" gas are way outa reach, IMO. Maybe someone can explain a "base number" and a "corrected number".......It took decades for the best engineers in the industry to reach the 1 for 1 horsepower to cubic inch ratio, now we're hearing about 2 for 1 and much, much more. To add to the mix throw in the shitty gas of today. I would really like to see how these dynos are calibrated, and when......Maybe take an engine to another dyno across town, change nothing, and see if the results are the same......Ray
PS, all the PS89 motors come out of my garage, never been on a dyno, (too expensive), and the cost of an afternoon on the dyno will damn near build another bottom end..........MP

3 OPEN flatbottom APBA seasons left.....Let's RACE
HONK if you voted for obama........
It's that button in the middle of the steering wheel........
maybe you are in the old school of thought here but im positive the grand mark has been hit by more than 1-2 over a period of time.with todays tech. i personally think it is well within reach,damn sure not with production style componets off the shelf,but a good plan and some money it can be very much done.
you might have crappy fuel.so might i but we still have alot of 93 octane around here that smells like it did 10 years ago.oh well another hatter of the ideathanks for the good advice moneypitt.
last i remember there is not much ford or chevy left wehn you go real big.aftermarket crank,rods,block heads,blahhhh-blahhhh-blahhhjust that the dist. doenst move
well maybe after all these years i should do ford and with alittle over 500 inch i can get 1,000hp and with a 600 inch ford i can get 1500-plus
