Just wondering if most racers build there own short blocks or do they have them built.
I have built a few street motors and they performed very well....i could save alot of money if i did all the stuff myself...any comments would be of help.
I am a new racer so i really dont need a monster motor right now but id like to know what other racers throw in their "home built motors"

i built my own motor and can hang with the leaders. this was my first season. do yourself a favor build a good dependable motor but concentrate more on handling. all the motor in the world will not on itself win a race. if your car can`t handle it makes for a very long night.

if you have confidence enough to build something to get you home everyday then build your own. i have never had a good motor but always run just fine most of mine i just pull out of a junker put a cam and oil pump in um and go. i ran a stock 307 out of a truck with 150000 miles on it for a whole season only had $100 in it and it made me alot more than that in the long run

I always build my engines and i would never do it any other way. I get most of my power out of the right cam and a good valve job which i also do myself.

The bottom line is that it depends on your knowlege, skills, resources, and experience. I'm not trying to complicate a seemingly simple question, but from personal experience, it took me a while before I became comfortable building my own motors.

With you having built a number of street motors, you should be OK with a race motor, just remember to adress those differences between the two. Of course, the race motor must be built for durability, higher RPM, higher temps and pressures, etc.

I'll tell you one thing, spanking the other guys with a motor you built yourself is very satisfying.

I Agree with everyone else. If you want a good motor and if your track rules allow run 305 heads on a 350 bottom end. It will go a long way. It gives you more compression. It will not do much though if your car doesn't handle good.

Those are some pretty wide open rules..JE makes a great piston..alot of good lightweight rods out there, callies or lunati make a great crankshaft..GM latemodel '492' castings come with 2.02"/1.60" valves..Brezezinski does wonders with cast iron..Several good carb builders out there (I understand KPLugnut is good w/them.) As far as the Hyd. cam goes, I'm sure there are cam companies out there that can grind whatever you need..
