In the process of building a new engine, mid season none the less but i am wondering what kind of numbers (horsepower / torque) i should be aiming for?

How much HP/TQ are you guys running in mod's nowdays?

I'm shooting for 600hp in the car. Although i get the feeling some guys (UMP) are running alot more, not sure but its just a guess. Some of the cars around here sound really good. Just trying to get a feel for what i am up against.

depends on what kind of track you run on adn what tires. Dry slick on IMCA tires 500-550 hp, tacky 550-600+ hoosiers more yet. You can overpower yourself real easy. UMP, USMTS guys I'm sure are pushing if not over 700HP but unless you can hook it up you can t use and its wasted and can make the car worse.

Yep, were on Hoosier's and run UMP rule set.

The reason i ask is, me and my brother were talking about how much power some of the guys were running in the mods in our area. So i thought i would post and ask. Were guessing between 600 to 700hp.

Were building the most power we can afford, so just kinda wondering if we are going to be in the ballpark or not.

700 plus HP seems to sound about right from what i see around here. Alot of Little M's and 18 degree Brodix heads etc. I hear rumors of one guy running a 790hp 377, but he is a highly sponsored driver so i kinda believe it.

Anyway thanks for the response, we'll just build what we can and go from there.

Well, thats a breath of fresh air, or a sigh of relief. 550 hp is doable by a low budget team like us.

700hp small blocks start to get really pricey and the durablility goes down the shoot as well it seems.

We do run the Burg, and hoping to run Florence soon. Also we run some KC and Brownstown Ind.

Something else to keep in mind, prob one of the best things that happened to us (in a roundabout way) was getting rid of our 406. started running 355 and 377 motors and they had just as much HP but were more drivable on our super slick tracks because of the softer torque. The bigger motor was just too much on anything but a tacky track, for us anyway.

Yep, were putting a 23* 355 together now, and 377 this winter. Like you said, and alot of others told us the big cube motors dont seem to be good in the modifieds.

Also, my driver found that he liked the higher rpms we turned with the smaller motors because it really helped him get into the corner. The car/engine would really brake itself instead of coasting in.

Top few around here are 406's a tad over 800 hp. And they seem to put it to the ground.

don't forget that alot of the horsepower figues people quote come from "magical dynos". if it was that easy and in-expensive to have some of those figues, everyone would have them.
an injected, all aluminium, 12deg cnc heads, best of everything, professionally prepared and assembled, with years (and hundreds of thousands of dollars) of research and development 410 outlaw engine (cost like $34,000) are only just around the 800hp mark.

some of the figues guys will quote you are very imaginative. even if they have "dyno sheets", unless the dyno is in a controlled environment (humidity, temp, ect,ect.) and calibrated, those figures don't mean much.

Rocket 36 i agree with your synopsis. 800hp is hard to come by, top notch thru out and durability goes way down. Requiring constant attention and freshining about every 50 to 100 laps i hear.

Dont want to go that route.

19J, i agree with you as well. Torque is a big factor in our minds as well. So were trying to keep it in check with what we want out of the motor.
