chevy 350 and trans question

[ATrain707]

hey guy i just bought a good running 350 with some bolt on for 500. i have a 68 chevy truck long bed with a 250 straight six and a 4speed with granny low, anyways will the tranny bolt up to it? or what will i need? also what other stick shift tranny will bolt too it that i can use with little to n mods to get it to fit. n if i did an auto tranny whats a list of parts i would need and what tranny? and how would a Chevy Saginaw 4 speed trans work?

Your 250 bellhousing will bolt to the 350 with no modifications needed. If the 350 is 85 or older and did not come with a manual transmission flywheel you can use the flywheel off the 250. If it is 86 or newer you will need to get a 168 tooth flywheel for a "one-piece seal" crank.

Any 68 or newer 3 or 4 speed truck transmission will bolt to your present bellhousing without modification. You can install a 67 or older truck transmission or a 55-up car transmission if you get a spacer ring like this.

The Saginaw 4 speed is a car transmission and will need the spacer ring.

Sorry, but can't help you with the automatic as all my trucks have manual transmissions.

you will need a cherry picker....
as mentioned above, it will pretty much bolt right in. your fuel lines and radiator hoses will be different, your fan shroud might not work, but the mounts and trans are pretty much the same. wiring is pretty much the same, once again depending on the year of the donor

ok sounds good, the motor cam out of a 72 chevy 4x4 truck he had a 4speed trans hooked too it i think, it came with the flywheel and new clutch mounted to the motor i was told the block was newer year and the heads were from 70s i ran the numbers off the block but came up with really nothing, maybe if i post the numbers up someone could help me with this? aslo i was told its a 4bolt main is there any other marking to tell the year of the block? anything?

You can determine the year from the casting date. This will be on the top rear of the block behind the intake manifold. It will be in the form of a letter (A through L) for the month followed by 2, 3, or 4 numbers. The last 1 or 2 numbers will give you the year. You will find a similar casting date on the heads if you want to take off the valve covers.

hey guys will my starter from the inline six work with the 350 fly wheel?

[mr48chev]

I did a bit of hunting and found this . A page worth saving. http://www.v8extremo.com/forum/viewtopic.php?f=4&t=168

Looks like the block is from a 92 Target (GM fleet replacement) motor originally.

The info says it is an early style block with a two piece seal. The heads probably came with the block and match up too but you will need the casting numbers to figure that out.

ok so its 10066038...350.....92....4...Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico". how are these motors? i know 350 are good but i mean this year 92 4 bolt main? thanx for all the help guys

[ATrain707]

hey guys, one other question theres no dipstick on this block there is some what of a tube stick out of the block does this need to come out to put the new one in? i havent taken the oil pan off yet. here are some pics

[ATrain707]

hey i just fell in to sum $$ lol any way i wanna chage over to a auto trans if i do and bolt the mounts to the frame for a v8 and use a tubo 350 trans do i have to do any mods to the drive shaft to make it work?


ok never mind, after doing some reading, way more work than what i wanna do right now, so what the best 4speed trans to put in my truck and will bolt right when when i put in my new 350

[Tx Firefighter]

The Goodwrench 350s are 4 bolt main engines.

[ATrain707]

are they reliable? the goodwrench motors?

[Tx Firefighter]

Sure. It's a brand new 350 built by the General. Good stuff.

does the linkage for the clutch mount to the block or the tranny? i know one side mounts to the frame

[Tx Firefighter]

Clutch pivot bolts to the block.

[ATrain707]

So is there a spot on the 350 were it bolts too? I have a straight. Six in it now n gonna put the 350 in with the stock 4 speed

hey guys i was wondering if u guys could help me with this setup. i have a 68 c10 im working on with a 250 straight six and 4speed granny low it looks like its not the stock bell housing and it looks like the mounts are sitting in were the v8 mounts and also looks like the clutch linkage was also moved on the frame. i gonna be taking out the 6 and put the 8 in so if this is already setup for the 8 it will be an easy drop in? cuz i was gonna mount the v8 were the 6 was mount and it was gonna sit back farther but now i dont i dont think thats the case, any thoughts/ ideas? here are some pics i took alot lol

[ATrain707]

more pics

[ATrain707]

and.....

[ATrain707]

too me it seems like the I6 is too far forward? i have a 69 parts truck with a I6 an it seems to be sitting back farther, i havent looked at the way its mounted in the 69 yet

[ATrain707]

and that z looking bar for the cluch linkage do i have to replace it? they have one made for a v8 do i need that one or can i use my old one whats the differents?

[ATrain707]

can anyone confirm about the pic of the I6? if it is mounted were a v8 mount, i just dont wanna have any problems when i start swaping out the motors, thanx

[67sss]

put the v8 where the I6 was. you'll need to change the Z bar set up, as it's different from I6 to V8.

another tip for you..on the top right hand side of this page there's a "Search" button. You can get most of ur questions answered by doing a search..AKA: z bar, I6 to V8(350) swap ect..

Give it a try, it works great. Good luck!
