I am going to be running a 350 chevy smallblock in a factory stock class on a half mile track and am wondering what I need to do to make this motor durable and what type of cam ( lift , duration, etc... ) I should put in it? This is my first attempt at building a race car and I need all the advice I can get. I will be running an 85 Olds Cutlass with a minimum weight of 3400#. I am also planning on running a Holley 4412 carb. What brand of gaskets - Fel Pro or Mr Gasket etc... ? Thanks , Kent

Call a cam manufacture for a cam recommendation. Use a heavy oil.

If you don't overdue it and go too crazy with your stock combination, it should be a reliable motor. When you start putting a lot of compression into a stock motor your more likely to have problems.

What does your rules alow you to do,but most of all,what does your budget allow you to do. For alot of 1st timers,they go out and spent wasteful dollars on things that have no effect and no help in the performance department. If you have done a compression test on the cylinders and everything seems okay....spend some money on the HEI with upgrades,a good cast iron intake manifold to go along with that 4412,nice big exhaust with good flowing mufflers,and a nice clean 4 core raditor to keep it cool.
Sure people will tell you to go out and build up that motor,but start out smart and learn the race game before you spend a ton of money just to learn you spend a ton of money.
Tire size,and tranny will have alot to do with the final drive you are shooting for. Need to get the gearing right to hold those rpms up when coming off that corner.
Can you run race springs up front and in the rear?
Pieces of a race car are like a puzzle,they must all fit to to get a complete picture.
Take the time to learn,up grade as needed.
You can always start a motor program during the off season to be fresh for next year.
As for gaskets,I like Fel Pro,hate Detroit Gaskets.
Sometimes you can find good deals for gasket sets thru ebay,Day motorsports,JR motorsports and others.
Take your time and read the rules to make sure your money goes to the right area of the car.
There will always be someone faster than you,but don't forget the consistent cars finish up front.

look around on ebay and you can find some good parts for cheap find a set of hypertetric flat top pistons and use clevite 77 bearings,felpro gaskets. myslf i usually just find a junker with a 350 in her every year and just get a good re ring kit, oil pump,cam and valves springs and have a good reliable CHEAP motor and it will last all year this year i broke down and bought some flat tops this year but i will still have less than $400 in this motor when i'm done and i will run just as good as the guys with 1000 in one

Thanks for everyones input. I just bought a 76 Monte today with a sweet running 350 that I will be putting in my race car. Yes - I am able under the rules to use aftermarket springs and shocks and everyone has to run the "track" tire. I am a beginner and really appreciate all of this advice! Thanks, Kent

my first season was all about getting around the track, suspension, weight transfer, shocks, tight, loose, camber, toe out, ballast, bite, and learning how to drive like a cunning physco nut with smarts. after that comes juicing up the performance. you'll need to get these things down first, all the horsepower money in the world means zip if don't have a car that will turn and once you get it to turn well, and can drive it well, then visit the piggy bank. just my open onion.
