Hi I'm new to mini stock and racing in a division with a $500 engine claim rule. I'm setting up a 2300 and need some basic info on what would be the best mods for the engine. As stated I have a $500 claim so I cant get to wild with the mods. I have the stock one barrel carb on it right now and timing is also stock. Any help to get me started would be appreciated.

Hey I am new also. Check out www.racerwalsh.com They have a tech article for the 2300 engine. Go through the site map towards the bottom of the home page. You will see it. Also (I'm NEW TOO, so you may want to get my opinion confirmed)I think one of the easiest (and cheapest) ways to pick up power is by milling the head. I think you can mill it 0.110 inches but not sure. But racer walsh has a lot of info that would be good for you since you are new like I am. Also if you do or find anything that helps you out let me know as I have been in the racing business for about a month myself!!! Since I am new to racing. I am learning alot about tires set-up and other things. I have also learned that tires arent cheap and they are easy to ruin. I set myself up with a tire shop, and they are keeping the "good enough" performance tires that they pull off of cars for me. I am going to be using used tires until I get the set-up I feel best with down. Hopefully this way I save money through my trial-and-error phase of learning.

I RUN A 2.3 STANG "ON DIRT" 1/4 MILE TRACK. I'VE HAD MY HEADS MILLED .145 AND MY TIMING IS ADVANCED ABOUT 30---SOME MINISTOCKS GO AS HIGH AS 40. THIGH HIGHER YOU ADVANCE THE HARDER IT IS TO START AND IT RUNS KINDA RUFF AT LOW RPM--BUT ONCE YOU GET ON IT YOU CAN FEEL THE DIFFERENCE.
GOOD LUCK

i run a 1/4 dirt track...
we advance the came up to 8 or so
and we run timing at 32 to 35
we have ran 38 to 40 timing and when you turn her off she likes to kick and jump and stuff like that
we just kinda like 32 33 for the timing
i also mill my head to about 125
it really helps

How about for carburator and cam shaft. right now I use the stock Carb and CAM.
The carb is a 1 barrel. I don't think it could afford a holley 350 or 500 just too much money any other cheap alternatives or mods.

Your help is greatly appreciated.

well man, i think the holley 350 or 500 is the norm at my track for the ministock, actually the 500 i dont know anyone that uses the 350, BUT someone in here said that the 350 would be better. I dont know for sure. as far as cams... well my machinist says to go with a 510 lift solid cam. but to do that you have to get a whole bunch of other stuff to make it work. like valves springs, lifters, etc... there is one on EBAY right now and the bid is at 102 dollars. it comes with the springs too. as far as the claim rule goes... has anyone ever had their engine claimed at your track? Let me know about it, there are no claim rules at my track.

I USE A 350 HOLLY BECAUSE IT CAME WITH MY CAR, I LOOKED AT THE 500 BUT AUTOZONE WANTED ABOUT $230 FOR IT-- ONCE I GET SOME MORE TRACK TIME UNDER MY BELT I MIGHT UPGRADE. I'VE BEEN TOLD YOU CAN ADJUST YOUR JET STREAM WHICH WOULD MAKE A BIG DIFFERENCE????
ANYWAY AS FOR THE CLAIM RULE MY TRACK HAS ONE IN THE RULE BOOK TOO....... $250 FOR THE HEADS UP, BUT I'VE NEVER SEEN IT DONE.
ANYWAY COUPLE NIGHTS TELL RACE DAY GOOD LUCK TO ALL

You probably need to get ahold of Earl Parker or KPLugnut for carb issues. The 350 is the better choice for you application in my opinion, but the 500 will work and I bet most guys there are using it. What ever carb your using, just take the time to make sure all the circuits are set up properly. Determine which power valve you need (don't block it off). Put a fuel pressure reg on (set at approx 6 lbs). Someone said it before, the adjustable timimg gear is a must. The bottom ends are naturally tough peices as the have a main for every rod. You can get by without the high doller light weight bottom end peices. I have run stock bottom end components with my not so stock head with no problem. Just put good rod bolts and rings in. The head is where the power is at. Also most of the money... It just depend on what you want to do and spend. Mill the head valve job and decent hydraulic cam makes a difference. .180 off the head solid cam bigger valves, etc makes a bigger difference but is going to blow away your claimer budget.

I wrote the Holley tech guys about the carb selection for a 2300 cc dirt tracker. I told them I was running 60 over pistons, a hefty cam, and my RPM range, 7000 +. They wrote back saying that the 350 would give better throttle response and pull. BUT the 350 runs about 40 dollars more than the 500.

Hey Newbie,

Your $500 claim shouldn't include your carb, header, or performance pullys and fans. You need to get a Holley. I can't recomend 350 or 500. I have a Celica with a 500, and my buddy with a Ranger uses 350. Last week I was second place to him in the race. We have the same claim on ours. I spent my money on a performance cam from www.blazespeedshop.com he also does fords. Put double valve springs, adjustable timing sprocket, smaller crank pulley, larger water pump pulley. We cannot port or polish our heads. This stuff was probably a little over $500, but in a claim you should get the engine of the person that claims your engine.

Head work wil give you the best results for your money.larger valves, cam,solid lifters,porting{expensive},milling etc.if you don't run a 350 Holley,a less expensive alternative is those old"flat top"autolite/ford 2 barrel carbs.

well if your on a tight budget id shave the head 150 thou, to start with and if you cant afford a holley id go to earl parkers web site www.parkercarburetion.com look up motorcraft cfm ratings and you can tell which motorcraft carb you need i would recommend the 357 cfm you can get it across the counter rebuilt really cheap and will really out perform a one barrell, also if your running a stick get you a escort clutch and if your rules allow it turn it down as much as possible, then the next thing would be to hull every ounce of weight out of the car it dosent need. dont sacrafice safety here tho, get that car where it will handle good ,lower it, get it set up right change the springs etc.
