posted January 02, 2003 09:33 PM Looking to buy a Hobby Stock. Other than running a 2bbl Rchester aluminum intake and headers anything pretty much goes. Am severely Sb Chevy retarded, looking for a relatively inexpensive combo to use. Or else I'll have to try and stuff a 383 Dodge in a Metric chassis.

I have only built two motors for street stock dirt. I mostly built llm asphalt motors. The best low buck motor I ever built was a 350 with 11.5 to 1 bought the speedway pistons hyper $150. A set of there x rods. I know this is going to sound odd but I used a 305 crank I think the number is 1182 its a steel forged factory crank its 4 pounds lighter then a 350 crank. Beware some 305 cranks are the same wieght but they are the cast ones. After I polished the rods the rotating assmebly ballanced out nice. Get a set of studs for the mains. The hole key to keep a botom end to gether is the bolts go spend $60 on rod bolts and 60 for mains. Well worth the money. And the balanceing $180. As for heads a set of Iron eagles if you can aford is the hot ticket but don't buy the big ones if you can only run a two barrel. If not a set of 461 or simular camel heads are very good with a two barrel if you can do some porting even better at least gasket match it. Z 28 springs and pin the stock studs if on a real tight budget. The place you need to spend money is on the heads intake cam and carb. Wheather it means buying better parts or porting. Most of the time its cheaper to buy a set of Iron eagle then redue a set of stock heads. Here is the hot tip of the day Ultradyne cams they have a website look them up they are a little spendy but they will make a cam just for you. Well worth it. I have seen gains on the dyno of 35 hp over a purpose built book cam. About $300 for cam and lifters. Again well worth the money and time. For a round 1200 dollors I did the porting of heads and intake had to use the cast two barrel. Polished the rods and did the assmebly we made 410 hp with a holly 4412 with no mods. The motor ran 50 shows running in a llm asphalt at 6800 rpm. Never freshened untill now. May be a lillte luck. But you should get aleast one good season out of something like this. Just take care of it meaning oil changes and don't overdue the spark timing. Good luck. Mike
