I have an old good dead small block

When oil pan was removed, this surprise appeared:





So, now I need new camshaft, rods and pistons.
What pistons and camshaft should I get for stock/street engine? Is it good choise a something like COMP Cams kits for camshaft?

Just use stock type flat top pistons and a cam with a rpm range from just under 2000 rpm to about 4500 rpm. You get the best street performance and gas mileage that way. To many people put bigger cams and ruin the driveabilty and performance.I have used this on many engines I did and never had a complaint.

Yuck! Look at the sludge in that pan. Sorry to hear about your motor. That didnt look like a very old crate engine.

I updated information about my engine to make clear my problems:

Small bloch chevy 350cid, number 14016379
Engine totally destroyed. Looks like something wrong with oil system.
This 4-bolts engine run with Rochester Quadrajet carb, I want to build stock engine.
I have only block as is, and need to build engine from scratch.

Please advise me what spares I may order according my list. I note some details about each spare - beacuse I dont know enough information yet about really quality spares for Smoll Block - usually we order spares of some popular brands and I'm not sure, is it correct and cheap way.

I need new:
- timing chain kit (I think about COMP Cams kit)
- cam shaft + bearings + push rods + hydraulic lifters (again - I think about COMP Cams kit. Is it good idea to order tuning cam shaft without any tuning in other area of engine?)
- pistons + rings (set of 8) - bore diameter now (before reboring) is 101.74mm. After reboring will be something about 102.20mm or more - anyway I may bore according piston diameter. But I'm not sure about what pistons should I order - what brand, what price - according Summit or RockAuto price starts from 15$. How I may reach balance price/quality?
- connecting rods - the same situation
- new oil pump - ACDelco, Milodon or something elese?
- crankshaft main bearings (size I will detail later - tomorrow I'm going to buy another crankshaft at my local junkyard - anyway it will be better than my crankshaft)
- rod bearings (size I will detail later). Clevite?
- kit of heads bolts. ARP?
- kit with all valves (size will be detailed later, after a will check and measure valve-stem gide)

The main criteria is balance between price and quality of spares - due to very long terms of shipping and weight of spares (= high price of shipping) it's not possible to compare spares here.

Thank you for support, mates!

Check here, as they are about the cheapest here in the states
for rebuild kits.

You should do the bore before you order pistons.

You really need to tear into this engine a bit farther to tell exactly what parts you are going to need.
Just by the damage ed parts it look like you will be needing a new crank.
The bores of the pistons will also need to be checked for damage and how much there is.
Boring a SBC out 30 thousands is a good reliable up grade.
you will have to purchase the correct pistons and rings to go this route.
Finding a good machine shop to do the needed machine work to the block might be a problem.
Using a junk yard crank is really NOT a good option.
The crank and main bearings are the life of a SBC
The cam shaft is more than likely still good,I would replace that with a nice low end torque style cam shaft.

I am not really sure how ANY American vendors handle shipping parts to your part of the world.

Good luck with your venture.....

I would be curious what all the parts, machine shop time, etc....would add up to vs a new crate 350 motor....$2,395.75 from GM 350CI- 290hp 4 bolt block.....

thanks for your opinion, mates!

yeah, now I need new crankshaft, but I try to find any in my local stores or shops - due to very high weight it's very expensive to order crank from US.

I checked block visually - all ok, but I'm going to make pressure test of the block.
The problem is, that in my city exist only two place, where I can do all machine works..

Let's divide all engine components at groups and make clear some details for each group.

At first, I found COMP Cams kit for street usage, 2000-6000rpm
http://www.summitracing.com/parts/CCA-CL12-209-2/

and COMP Cams timing chain kit
http://www.summitracing.com/parts/CCA-2100/

But I'm not exactly understand what means note "Will not fit factory roller cam applications".

a local machine shop can rebuild an engine for close to the same price as a brand new crate engine.
the major differance is the crate engine is BRAND NEW.
the also come with a warrenty that is good at any GM dealership.

I have one in my early that is in it's 2nd vehicle.getting ready to put it into it's 3rd here soon.

It has close to 100,000 hard miles on it.

Some SBC engines (305's)came with Roller cams from the factory.This cam will not work on this style of engine.
