What price in U.S is for the 400ci engines in standard and ok shape should it be? early 1965-67 and 68-69 ?

some tip?

Oldsmaniac

From what I have seen the G block 68-69 400 is easier to find and less desireable than the earlier E block 400. I see these later ones for sale in the 400 to 600 range. As for the E block I have seen them from 800 to 1000 dollar range. The 65 400 is more scarce. I believe it is a B block.

Oldsragger

Ok thankyou

oldsmobiledave

$500 US for a 68-69 core & $1000 US for a 66-67 400. Never owned a 65 400 but would likely be around $750.


These prices reflect what I have paid in my area.

Oldsragger

aha ok, well i have one i will get very soon ,the casting nr on the block is 396026G so it seen to be the longstroke 68-69model engine, and it`s done new rebuild and tuned and have a rate on 381hp and 576nm (torq) and its (overbored?) so its 407ci now. the nice thing it follows documents with the engine of all that have been done with it. I hope it was a E block. (the high rev engine?), that i read on google is a good choice,, but it think it will be a little better anyway than the 140hp 300nm 307ci i have now . :P im not going to use it for race and high rev so i think the engine will be a ok choice in my large delta 88.. not rigth a sleeper maybe but nice to have some few more power under the hood

but i guess it will be a good buy then for 2940US when the engine is built for 7938US and its almost turnkey engine, i use a valuta calkulator on these numbers so i guess its very near the us price vs norwegian krones.

Another thing i have heard of that its expencive to build and tune up this Olds engines? than forexample a Smallblock ch**y , but in my opinion i will do what ever it takes to have a good olds engine in my oldsmobile than use a nother brand engine. hehe

jankyrre

Kvar i Sogn og Fjordane då.Eg er frå Sykkylven Møre og Romsdal, om du veit kvar det er.

Gloppen kommune, jess har vert der før.

G block is a great street motor with loads of torque.

Oldsragger

Sounds nice, what is the orginal Hp and torque on a G block with 4bbl carb and C heads if you know?

Nilsson

G block used in the 68 442 is 350hp for the auto and 360 for a stick car. I am sure 69 would be the same, and of course that would be C heads. The only other model that used the 400 was the Vista. Not sure what heads were used on it but the hp rating was significantly lower.

allyolds68

I THINK (I don't have the assembly manual in front of me) that the Vista only got the 2 bbl LC 400G. They all (except the w30's) had C heads

dnmfranco

325 for the auto;350 for the manual and lastly 360 for the w-30's
all C heads except W-30 - D heads

allyolds68

You forgot the Turnpike Cruiser which (like I said.....I THINK) is the same as the motor used in the Vista. It's a low compression 2 bbl.

dnmfranco

yes the one I had Ca heads???????? 290 hp
I know they only had 2 inch valves perhaps the a designated that

oldsmobiledave

You left out 350 hp for W-32 equipped cars (1969 Automatic)

dnmfranco

yes I did ty, how did I forget that with the most recent thread on................ oh a w-32 for sale. oh well

Oldsragger

Hi guys, thanks for answers, well now i have more info about my new engine, the engine is like i sayd a G block with casting 396026G and with C heads, and the number under the head is 38M386314 is it possible if anyone can help me to identify where the engine comes from with that number maybe?

i have all the papers from the engine build now...
it is overbored 0.03"
Hp: 381,1 on 5000rpm and 596,7Nm = (438.8 Lb-ft) on 3750rpm 400.9 lb-ft on 3000rpm.

The engine have ned bearings over all, new pistons and rings, modified rods, polished crankshaft, and balanced pistons,rods,crank, the valve seats is overhauled, the head are ported,,new oil pump, walls in the oil sump. follow with new msd ignition,eldlebrock carb,edlebrock intake etc..

3=Oldsmobile
8=1968
M=The car was assembled at the Lansing Michigan plant.

Dont think you can find out any more from the VIN derivat.

Oldsragger

Ok, takker.

Octania

The range of the final 6 digits can tell if it was Toronado or Some Other Model. There are many other clues to Toro-ness though.

Heh I missed that part of it being a G 400 so that rules out Toronado obviously. So, it was a 68-9 442 or Vista motor.

If the bore codes are D it would likely be a W30 motor, otherwise, hard to tell any more detail.

Oldsragger

Im just asking here instead of making a New tread..

what Oil type do yall recommand on these engines? 20-w50 classic? something else?

oldsmobiledave

Run a high zinc 15W40 diesel oil & you will be safe & lubricated. I like Brad Penn & Joe Gibbs products for race engines.

Oldsragger

Ok, i will try to find 15w40 diesel oil some place here then, i have not heard about these product in my contry but i will see what i can find in the local v8 store.

Oldsragger

Hi,it`s me again, New question,, what converter should i use With this new engine? should i just use my Stock one? im a little New on converters so i dont have so much ideas about it. the car is in daily use driving, not racing car ,lol but, somethimes i like to press the trottle in the floor.

I have stock rear axle 8,5" 10 bolt, im not sure what gears but its nice to long trip cruising and street cruising. i have 275/60/15" wheels in rear and Th350 transmission, i will upgrade the transmission later cause i dont know if it can handle 438,8 lb-ft in 3750 rpm in pedal to the floor accleration. (it depends on the stall speed convertion right?)

well i just need a tip of what converter that will be ok and the engine will not rev to high in daily use and cruisings.

thanks

64Rocket

Do you know any of the spec's for the cam?
If it is just stock or a step above stock, the converter you should be fine.

Gene

Oldsragger

I guess it`s stock cam since it stand nothing about cam upgrade in the building papers. you mean i should just use my standard converter? im think about it, things have working fine anyway, i think i will upgrade the gearbox later so maybe i can upgrade a converter then too.
So i will just have an engine swap and use the car like normally then
