Looking into running a street stock class and the engine rules are calling for stock parts with a 363 cubic inch rule. Does anyone have a comment on claimer short blocks by some of the vendors like Speedway or others. The rules also state 194 heads also with no work. Any suggestions for a small block Chevrolet?

I KNOW PEOPLE WHO HAD PROBLEMS WITH MOTORS FROM MIDWEST, SPEEDWAY, AND STORM PERFORMANCE OR SOMETHING LIKE THAT, THE LAST ONE ADVERTISES IN ALL THE MAGAZINES..

IF IT WERE ME ID BUY PARTS FROM COMPETITION PRODUCTS TO COPY A MIDWEST MOTOR AND GET A DECENT MACHINE SHOP TO DO THE MACHINE WORK THEN ASSEMBLE IT YOUR SELF, OR GET A FELLOW RACER TO HELP YOU, I HAVE BUILT A LOT OF MOTORS FOR MY COMPETITION RIGHT NEXT TO ONE OF MY OWN, AT LEAST THOSE GUYS ARENT CALLING YOU A CHEAT THEN WAS MY THINKING........

WHERE ARE YOU ASK ON HERE YOULL GET HELP, OR JUST GET A BOOK AND GO FOR IT THATS WHAT I DID 13 YEARS AGO TO BUILD MY FIRST MOTOR ONLY THING DIFF NOW IS I HAVE BETTER TOOLS AND MEASURE A LOT MORE STUFF TO MAKE SURE ITS RIGHT!!!

I have in the past run motors built by well known builders in this area,but I am now going to put together a car to run a local high bank dirt track with alot of spare parts we have laying around. Of course we have a nice good to go 454,but this class has a flat top 9 to 1 rule,with 194 heads,at 363 cubic inch,with a 4412 2 barrel. I am just looking at different options as for a engine. I will talk to a engine builder tomorrow to see what he has to say.

You'll definitly save money either doing it yourself or having someone you know build it. I have ran a basicly stock bottom end 355 for two years. It has good power and the most important thing is it's reliable.I have under a grand in it.

I have ALWAYS BUILT MY OWN MOTORS. Think about it..aren't you just out there for the fun of it anyway? You've got several months to get a good motor together, so, what's standing in your way? The best advice I can give to you is to talk to some of the guys you race with and find who they are using locally to do their machine work. I don't have the precision tools nessecary to check what the machinist has done, so I had to find one that I trusted. Once I got to that point, the rest was all downhill. I did make the mistake of using a "production" shop here in this area, and wound up with work that probably have been fine in a motor which seldom saw revs higher than 3500. After making that mistake I sought out the guy that was doing the work on the Sportsman motors and asked him to do my work. Believe me---there is no such thing as "cheap" machine work!
Get help from the guys you run with. Get work from a reputable machinist. And get professional help in choosing and installing a camshaft>>>IT IS THE SINGLE MOST VITAL PART IN A RACING ENGINE!!! And most of all-have fun at it.
