Thread: 305 question

Tweet

whats up guys, i am new to the world of v8's but i will get to the question. i am in the assembly portion of my engine, and i cant find the main bearing oil clearance tolerances or the con rod bearing tolerances. I am using plastigage. I haved learned so much reading old topics and things and let me tell you yall are great. I would be real greatful if somebody could point me in the right direction. The haynes book doesnt even have this info.

Welcome to CHR. Techinspector1 should be around i think he would know this

not trying to get an attitude tech inspector, but i aint new to the internet, or looking up info. I dont sit around and wait for people to serve me anything. But i dont need to waste my time talking to people that think they know everything. Also you say this site is about giving information huh. Well think about what u said. U would rather give info not take it. well if u dont want people to take info u give why give it? What is a forum for then. Thank you Streets i will check on some more of those search engines. Techinspector sure knows how to treat people too. Please open your mouth and insert foot.

my apologies go out to everyone on this forum. Just felt i shouldnt have been attacked like that for askin a question. Thank you though.

Thanks man. Okay here goes. The reason I am doing this rebuild is because its my 1st v8 rebuild. Right now I am searching this town for a cam bearing puller, once I swap the bearings the bottom end can go together. I am researching a cam kit right now probably gonna call up crane cams this weekend, and the clerk at the parts store is giving me a hand. I am cleaning the heads now, they are completely stripped down. The guy that gave me the engine said they were "circle track racing heads." well that tells us a whole bunch of nothing. My plan for this motor is to put it in a s10 and run at the 1/8th mile track down the road. If all goes well I am gonna scrap it or keep going. But I am really looking towards a 350. I spent many hours on this site looking at the 305 versus 350 wars. But to me its all about how you build it. I wanna run a performer intake and still bebating on a carb. I know they say you should plan things like this out, but i am not rushing anything. I really dont care to do the s10 thing, but its the only vehicle i think is pretty light, unless i get a chevette . But once again tech, i do apologize man this is a cool site and i would hate to get booted for my comments.

You can use a hammer and a really long punch that fits into the oil holes above where the cam bearings are located and being carefull knock them out..... Thats what I did to my 305 HO Motor

I also paid a machine shop $35.00 to install the new cam bearings instead of trying to do them myself

went to oreilys and talked to the store clerk that works there, and he said the same thing. $35 aint bad but i am gonna try and tackle them myself. thanks man. just got my piston rings in too, just gotta get my piston pressed on to the connecting rod tommorow and hopefully have the bottom end assembled this weekend.

You say piston as in one?

usually when their is a problem with a cylinder, piston or rod you should change the pair that sit in the same journal

My 305 had a rod knocking and i changed the pair in mine
