nothing is numbers matching. car is a really a 6cyl
will get numbers later tonight.

motor and trans is out

any decent crate motors besides for GMPP....

edit: 3956618 is casting number

 

casting number is above

heads are 3932441

vin on block is k0806cnu

is this a 327 or not?

will a 383 stroker kit fit this block or not?

thx all

 

Well the good news is that your block is the later "350" main journal block, not the small journal.

I can't tell you what it is exactly because that casting number was used in the 302, 327, and 350 in 68-69 (its the same block for all 3 motors). Not to mention if it is not original who knows what has been done to it.

If it is stock and a 4 bolt main then it is probably not a 327, conversely if it is a 2 bolt then it's probably not a 302. But if you pull the oil pan you can just get the number off the crank and find out what it really is anyway.

The heads are off of a 350, with 76cc chambers. They are not "double hump" heads. Changing these for a good set of aftermarket heads could really make your car come alive.

Edit: Looked up your vin # and could only find this:

All the answers you need are in there


And yes, a 383 "stoker kit" will fit in your block. What you have is a standard 4" bore block, just like every other 350 SBC or 327 or 302. They are all the same and can all accept the 3.75" crank and 4.030" pistons to make a 383, with your choice of 5.7" or 6" rods.

It's the most common stroker kit in the world, should be able to get one from any performance parts retailer.

 

thx all. going to keep motor now

pulling the heads and oil pan out tonight

the motor had great compression and never burned oil or anything. should i bore it out any further or anything? or should i just remove the old and install the new!

plan is now

larger oil pan, high flow oil pump, heads, roller rockers, fordged 383 kit off Jegs made by egal. reuse my old weland intake, demond 750 (or 850) carb, masd igniton (off old)

 

Well if the motor has never burned oil and still has great compression I would ask why mess with it? It's already forged internals right? Change the heads and cam, you can get 450hp out of that motor. After that if it still isn't enough you already have a good set of heads and your supporting mods, it would be easy to go to a stroker after that.

What is your budget? That will play a big role on how big you can go.

Just my opinion though,

Jeremy

 

well i am a tad bit crazy....

anyways i took the old heads off. (god damn they are heavy lol)
the pistons say 040 on top....so i guess the motor was bored .040 over.

Are you almost positive i can get 450hp with nice heads.

was planning on spending 4K for everything

maybe 2K and plenty left for a good spray set up

i just figure while i got it apart i might as well wait and do it right. dont plan on driving car till april-may

 

I just think you will have a hard time "doing it right" on a $4K budget. Especially buying new.

This would be a great motor to buy used. Might be a bit expensive to ship though.

I would say talk to SStrokerAce or HeadDoctor on the board. Or Lloyd Elliot, any of those people and countless other should be able to tell you what you should do, because most likely they have done it.

Your pistons say 040 on top? I don't know that i've ever seen that, it's always on the bottom of my pistons?

 

i guess i will just go wit a good set of heads. can always spay or boost instead of 383

 

Hey guys! I decided to do a bit of surfin' for info, & came across this Rod & Custom 327 build-up. They managed to eek out a respectable 426 horses, without injection &/or forced-induction! You might even be able to contact them for parts nos. & prices!
Check it out, it might help!

Well there ya go. 426hp with out of the box 23* trickflow heads. Send those things off to Lloyd Elliot and get him to fix you up a cam to go with them and I'm sure you can make some serious power!

 

wow thanks a lot! this is why i love this site!!!

going to put together a parts list and then will post it asap and see what you guys think. can't wait to start!

the idea of a 420-450hp 327.....ohhh baby

 

how about these heads

500hp outa 350......maybe 420-450 outa 327

 

That's 500HP out of a 383. This is from the Trick Flow website:

TFS-K314-500-450, 500hp/450ft.-lbs., kit
Kit Contents:
TFS-30400013-CNC 23 degree aluminum cylinder heads, pair
TFS-31402002 Hydraulic roller cams, each
TFS-9000 Pushrod length checker, each
TFS-31400510 1.5 ratio roller rocker arms, set of 16
TFS-31400915 Gasket kit
ARP-134-3601 Head bolts, kit
SUM-G001 Cam button spacer, each
SUM-G1792 Cam locking plate, kit
FPP-1205 Intake manifold, set
TFS-31478500 Billet timing chain, set
NOTE: This kit was dyno-tested on a 383 cubic inch short block with flat top pistons, Kenny Duttweiler 23 Degree cylinder heads with 72cc combustion chambers, 10.0:1 compression, an Edelbrock Victor Jr. intake manifold, and a Holley 750 cfm carburetor.

 

That sounds about right. My guess is there isn't a whole lot of difference between the heads on that test 327 and those heads from Summit, if any.

I'm telling you though, it won't be easy to get that kind of power out of off the shelf heads, just send them off to a talented head porter, the results will be more than worth it

 

10-20hp is not worth the added expense or time to me. this is a street car. the old set up was just weak and wanted to hang with some of the other cars around here.

later on i plan on either spray or forced induction. I will cross that bridge when it comes though. goal right now is 420-450hp at crank. 500-550 at wheels with spray or forced induction

maybe i should put the 383 kit in it while it is all apart....

my TH350 2800rpm stall coverter, B&M shift kit trans (rebuilt) should hold up for now right?

I have 245 tires on the rear so there will be no hard launchs, just alot of smoke lolol
