What's a mild 383 or 406, etc build run if i find used shit? You do machine work/build the engine?

 

i build engines. i let machine shops machine parts.

 

 

look at ohiocrankshaft.com or what ever there site is. take your block to them and just have the machine work done i thinking was 200 or so. but that was with me installing cam bearing ckearancing the block etc etc, when i just priced phils motor out ...ooppp's i didnt say that!

 

but why? a stock block/bottom end would be more to your liking in budget, and tons of fun to go fast with. plus i know you. you'll get bored with it or tired of throwing moeny at it and get rid of it!:p

 

and to make a 383 or 406 realy do work, you need a good set of heads, and so on. i know you your looking for bang for the buck. :cool:

yeah, but the car's fucking cheap so i don't mind throwing a bit into an engine if it'll rock out.

 

alright, well i'll start searching for a stock block and find a good set of used heads, an intake/carb and headers..

 

Any years/cubes specific to look for?

Finding a good core 400 takes some searching. I drove to Youngstown for my 509 stamped 400. You can find some "decent" stroker rolling assemblies online for not too much money (depending on what your definition of "too much money" is).

 

that cast shit wont live long with beating on it, or even being easy with it.

 

i just priced a all forged stroker lt1 build(just the bottom 1/2, no cam,oil pan etc) at i think under 3k out the door.together. and that was the works, level 2 block prep, etc etc. i would waste my time with cast stuff. it just dont live long and those cheap chinese parts life is like flipping a quarter. we will just guess how long it lives. but you get what you pay for. now if you was looking to build something cool and sell it, then maybe i would consider it.

 

but there are so many combos out there, its not funny. theres 100 different ways to build it and go fast.

3970010 is the block you want to look for IMO...4 bolt preferably.

 

 

 

These are both 4 bolt main engines. The impala most likely isn't.

 

the 2 bolt's hold 4500 or so just fine. arp studs and call it a day

 

 

edit i just gave away a 0010 4 bolt block, missing it caps. i just wanted it gone. hell i had it on here for ever

vortec heads, and the street dominator intake(dual plane, makes power off idle to like 6800 or some dumb shit) that works for them!

 

ill post the head numbers for those in a sec

you say the cast shit ain't worth crap, but isn't the stock bottom end cast? i doubt anything was forged back then....?

 

so rob, are you saying the engine thats in the car i should just leave as a starting point? i'd probably be satisfied with 400whp as I could probably hit my goal with that much, low 11's, seeing as how the 7 is lighter...

Rob, everything I've read about the high-nickel casting blocks has been pretty positive. What issues have you seen or ran into personally when dealing with this style block?

 

breaking them at 600 plus horse... that 18 degree 406 just pushed the crank out of the stock block. pushed the mains right out the caps. had billet caps and all.

 

ive had great luck with stock blokc and cranks, but they have there limit.

 

matt, the casting for some of this cheap chinese cast stroker stuff.IMO..well you like flushing money away? if so just hand it to me. ill put it to better use. granted i have seen some live, but its a gamble. ive seen them break under normal driving. but normally get beat on

 

ill put my money on forged stuff.

 

edit, there was some forged stock stuff wasnt there? just not worth the money

rob, ballpark it, what do you think you could get those parts for and install them for? and what's your timeframe?

 

or, if i get h/c/i and new carb setup, can you shoot me a install quote?

you could, but which motor is it? throw a cam, and a set of heads on it, but look on the side of the block to make sure it dont say 305!some of the 80 90's blocks ahd it stamped right in the side

 

lots of people will say something is a 350, but in the end its a 305

gm head number 12558060, throw a beehive spring on it with(with the stock spring you cant run more then .475 lift on one without machining them.beehive springs make it to where you run.560 max cam lift)

 

 

but the right rockers and pushrods and so on...

 

matt, theres so many different ways the build could go, aka shit i have to swap put on it etc, that change prices with more labor. a idea of what you already have to work with would give me a better idea on pricing vs your budget for that part of your build...you understand where im coming from here? like i said, give me a call one day this week and we can go from there with pricing. ill only tell you most cant beat my prices for the level and professionalism that you get

There is 100x more info available on small blocks than can ever be discussed here. Run a quick Google search to find a couple forums that talk solely about small block Chevy's. Read for a few days.

 

You can make 150hp or 500hp. There are more tricks and tweaks for these engines than any other ever made.

Some good info here. Just check your casting numbers before you throw parts on it.

 

Small Block Chevy Engine Block Identification

 

 

General Engine Block Specifications

While 6 different bore size blocks have been produced, the small block engine can be classified into 3 bore sizes and 3 main bearing sizes. 283 blocks (3.875" bore, 2.3" main), 302/327/350 blocks (4" bore, 2.3" or 2.45" mains), and 400 blocks (4.126", 2.65" mains). In 1968 the main bearing saddles were increased in size from 2.3" to 2.45".

 

CID Year Bore Main Cap

262 1975 3.671 2 bolt ONLY

267 1979 - 81 3.500 2 bolt ONLY

305 1976 - 96 3.736 2 bolt ONLY

307 1968 - 73 3.875 2 bolt ONLY

327 1968-69 4.001 (2.3" main) 2 bolt

350 1968-88 4.001 (2.3" main) 2 bolt

265 1994 4.001 (2.45" main) 2 bolt

302 1968-69 4.001 (2.45" main) 4 bolt

350 1968-96 4.001 (2.45" main) 4 bolt

400 1970-72 4.126 (2.65" main) 4 bolt

400 1973-80 4.126 (2.65" main) 2 bolt

 

Notes: 2 bolt ONLY means what it says. You will NOT find a 4 bolt 305 block (made by the factory). Period. Otherwise 2 or 4 bolt can mean either design...

 

Engine Code Stamping Numbers

All engines are stamped with an engine ID code, consisting of assembly plant code, production date and suffix code. V8 codes are stamped on a pad just forward of the right side (passenger) cylinder head. 6 cylinder engines are stamped on the passenger side of the block behind the distributor.

The engine date must precede the car build date, otherwise something is amiss. Some engine machining operations (decking) will obliterate the engine ID.

 

Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)

 

Engine Plant Code

Flint (Motor/6-cyl) F

Hydramatic H

St. Catherines, Ontario K

(McKinnon Industries Canada)

GM of Mexico M

Saginaw Service S

Tonawanda T

Flint (Engine/V8) V

 

 

Casting Clock

On some Saginaw blocks, intakes and exhausts a "clock" was cast into the block. The clock is a circle of 10 dots, one dot for each hour of a shift (usually 10 hour shifts). An arrow points to the beginning of the shift an another dot outside the circle indicates what time of day the cast part was made. Anyways, that's what that circle thing is (if you happen to see it on something).

 

Casting Date

Small block casting date is located on driver side rear of block on flange forward of bellhousing. Big block on the right side of engine above the oil pan rails.

Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

 

Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec

 

VIN Code Format

The vin code format is stamped onto most engines. The format consists of divisional identification number, model year, assembly plant designation and vehicle serial or sequence number.

In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stamped next to, or under the engine code ID.

Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the block pad (in front of the cylinder head), or on the transmission flange somewhere. Chevrolet issued technical service bulletins to indicate which engines were to recieve a vin stamp, so who knows what could have happend (or not happened).

 

VIN code format Example: 13N100001

(1 = Chevrolet, 3 = 1973, N = Norwood, 100001 = Production sequence)

 

Engine Block Casting Numbers

Notes (for below): "High Power" is the maximum rate HP this block was used for, "Low Power" is the lowest rated horsepower RPO engine the block was used in. "Main Caps" is the number of bolts holding the cap. A "two-bolt" main, or a four-bolt main. Four bolt main blocks are desirable in high performance applications because the extra strength of the additional bolts keeps the bottom end rigid and less prone to failure. However, a properly prepared 2 bolt main engine will work just fine (often times you'll lose a rod bolt before you break a crank because it's "only" a 2 bolt main).
