I was wandering if anyone could help with with a question, what kind of horsepower does an ASCS 360 car typically put out in order to be competitive? I do not care about which builder is better I am sure all the builders build fine motors, I would just like to know what the average horsepower is of an ASCS 360 motor.

Thank You

640's to 650's for an ASCS with 2 3/16's Hilborn. Close to 700 with Engler or Kinsler without the restrictors. Dyno's and builders will vary but this is a good baseline.

More than a 410 made 20 years ago.

 
 
 
They don't even know how to spell sprint car 
much less chromoly...http://www.ycmco.com

I know a guy who runs with the ESS and ASCS Patriots who has dyno'd at about 710 hp to the rear wheels. Perfecly legal motor.

640-650? 690-710 i would say is an average. the really good ones are in the 730 range. i had a 620 8 years ago that wouldnt get out of its own way.

do it in the dirt

I'm curious,has anyone dynoed a motor then put the sprint car on a chassis dyno and compared the # 's. i'm just curious as to the amount of HP/Torque loss through the drive line.thanks

I think your asking for a average, baseline, no smoke and mirrors, correct? keep in mind dyno's can vary 10-20 hp easy ,somebody, that gives you a questionable HP might be the same person that likes to alter his baseline ADR , or fuel mixture, A "DOA" engine can really sharpen up when choked for fuel! Agreed, todays 360 is much like the HP of a good 410 fifteen years ago (although the 410 is still 100lbs lighter and todays 410 is pushing 900hp but, big deal, its like compairing apples to oranges thats another debate, and a bit off the topic, umm nevermind? forget what I said, my bad) anyhow, the higher numbers found on pulls will be with motor combinations useing the latest and greatest equipment, Injection and Ignition systems seem to aid the ponies, compresstion helps also," You get what you pay for", something to keep in mind is the dependibility (life of your mill) could be shortened up with the larger #'s , Im thinking todays average and conservative 360 is the 635-680HP area , again it just depends on where you want to spend the dough , a good engine builder will be glad to fix you up with more HP for more $$!! ahh, the smell of HP, smells like green ink!

In the four years we have been dynoing our engines all of them fell in that range of 635 to 680 hp. I have heard of engines making 700 hp on the same dyno. But they worked for two days to get it. Trying everything you could to get every pony. So I would say you are right on the money. Drivable horse power is probably just as important as big horse power. Big numbers don't mean it will be awesome on the track.

Tell me how much money you got and I'll tell you how 
fast you can go!

there is a few items that have come out in the past four years that have helped guain 10-15 hp easily bolted on , otherwise, I think the real significant increases have been in fine machining and stroke dimentions , Im no engine buff, but its interesting the combinations that are out there that run good numbers on the jet, if a guy had the money it would be fun to play around, thats why the good engine builders have the knowledge us blue collars dont , My advice would be, (since you ask the question about HP ) your fairly green yet? If your looking at ASCS engine, Build a reliable mill or get a good relationship with a honest engine builder (this might cost some dough) make sure he knows your direction, get your feet wet,set your goals achiveable but not to easy, challenge yourself , respectable results will follow, race the track not your competition, keep your ears open to whats new ,dont forget whats old(sometimes it works better? ), and never give up!
