I am a new racer and I bought a pure stock monte carlo. Its got a 305 in it and I need to know what I should replace in it before next season. I am on a really tight budget (im going to school) and I can not afford to pay someone to work on it. Thanks for any and all info.

Well lets see here before we get to refreshing the motor does your rules say the motor has to be stock? If I was you I'd buy a 350 cause a 305 just really doesnt have any power. I mean most people aint as forunte as me cause i got a $8000 motor. But in your case your on a limit budget if you dont go buy a 350 and just wanna refreshin up your motor just replace the bearings, and the rings. The only reason I said anything about a 350 is that a 305 and a 350 interchange, plus a 350 has more power and prolly will be better to stay with the field

i agree go to a 350 . if you do it right it realy doesn't cost you that much . myself i i found an old truck that needed a over haul for 150 then pulled the motor and sold the truck for 150 without it i'm sure you could find somebody that needs a 305 for there street car so try to sell it then just get a re ring kit from midwest motorsports $80 or 60 for the cheaper one,a cam 100,good oil pump and double roller timing chain $50. and if you have a little more you can put in it then get a set of flat top pistons.i have less then 500 in my motor but i have the best handleing car out there so i can get by

The 305 is what you have to run,so your basic rebuild is in order. Maybe a couple of questions come to mind. Port Matching? Something you can do with a die grinder and alittle time. Valve work? What they can't see in the bowl area is maybe a direction for some work.
What type of carb? Q jet with the right mods is a hot ticket. If you can only run a 2 barrel, find which kind is legal and do some tricks to it.
If you are running a HEI,pay some attention to it. Thre are some mods that can be done to it for under $100 that will pay off big time.

i was looking thru my summit catolog the other day and they have a kit for you you'll just have to get the pistons pressed off and on the rods will only be about 45 to do that the kit is like 250 thats with everything you will need but a cam

after freshing up the bottom end up like the rest of the guys said i would spend some time on the heads, good valve job and springs ect. u can a few etra hp by a 5 angle valve job if u run a lower lift cam, also port work if allowed, and get the best flowing heads u can get and then fine a good cam to match then u will be set

The 305's came with different cc heads-you'll be sure to want a set of the HO 58cc heads Go over to Moretec.com for the casting #'s that you're looking for. You might call Wheeler or Midwest or J R Motorsports and buy a set already preped cheaper than you can buy a set locally and have the work done. They are able to buy that stuff in such quantity that the local guys can't compete---if you don't already have the castings.

Here is another approach, 305 engines are almost falling out of trees everywhere. If you don't have engine work experience I would look for a low mileage used motor, do a compression, and leakdown check, and RUN it. Your first season is spent learning how everything else works and you should not have to worry about a homebuilt motor. Keep the one you have for a spare. Ive been there.
