Well as a lot of you know...cause you've been buying my parts I'm building me a 383 stroker to drop into my car.

I've read a lot about how people have asked about cost to do it and what has to be done in order to get a motor this size into this car. Well as I build mine I'll show pictures and details about things.

Of course I might jump the gun on something..so you might see my oops that I have to fix later on.



As you can tell in the first picture we went ahead and just cut out the two cross members and completely unbolted everything to get it all outta the way. So much easier to see and weld this way.

Now this is our guessed at location. As you can tell I think we could of left the middle support. But we'll see when we get everything a little more solid in there.

Now when you do a build you always have to apply new paint...That's gotta add atleast 15hp ya know.


But anyways before the half a million questions come in. I'm still waiting on the transmission.....

But as far as cost I'll add to it as I go.

Now remember all of this is off the top of my head. So I'm sure I forgot something.

 

now this is what I'm talking about, an rx8 with a carburetor

and because you used blue paint thats at least 25 not 15

not sure that build sounds like 500+ hp. What compression are you hoping for? 10.1, 11.1??

 

Cross Breeding O.o lol

 

Looking forward to your build I was raised buy a bunch of hot rodin gear heads so this is right in my wheel house

 

chevy small block swap. you are the man.

i want to do this one day.

 

^yea this is up there on my list of things I want to do too, as well as a S/C kit or a LSx swap.

thats a long ways off anyways.

 

i'd rather do a LSx+t56 swap than FI. but a turbo would be a lot more simple.

 

cast iron block - that's going to be a heavy motherfather

 

subscribed! very promising good luck dude

 

An LSX swap is one thing, but I'm disgusted that you would use a carburetor. Pre historic garbage. You're like my old neighbor who sold his C6 Z06 so he could drop a carb'd SBC into a 94 Firebird. Carb'd 383's are pitiful engines without spray.

 

^do you know what your talking about?


cuz it just doesnt seem like it at all

 

Hopefully whoever painted that block isnt the one doing this build

 

lol You don't agree with my over spray??? lol Nothing a little paint thinner didn't take care of.

 

Well I could say yes and no to the carb. Fuel injection does have it's benefits but why spend the 5 grand for the LSX which is only like 335 hp or something. I'm not sure of numbers but I know it's in the 3's I can build this engine all brand new besides my block and I'm figureing my total cost with the transmission will be 5 maybe 6 and I spent 1250 for the transmission.

your totally right....that carb 383 has to be slow as hell.

 

Oh and yes... I actually carried that damn motor from the car...threw the yard....and now the steps to my basement. I only made it from the car to porch before the crank had to go. and yes the block by it's self is still heavy... I'd say about 100 pounds.

Before I install this motor I'll weight each item so I'll know a exact weight of the motor.

 

I like it, but, yah, the carb is going to be a bit tall, and wow, to get 500hp out of it N/A, you know you're going to need that lumpy cam and pretty good heads to do it with a 383 stroker.

Iron block typically weighs 90 lbs more than an aluminum block

Tear it up man! I love seeing these V8 RX8's coming out of nowhere!

 

Well 220cc heads are good at .5 lift to about 570 hp..and my lift is like .56 and yeah my cam is a huge lobe cam. I went to the street/strip cam's and the last one said it wasn't drivable..track only. Next one said very rough idle...but could be driven. The one below it said something about rough idle but still streetable to someone who can tolerate it.. my advertised lift is like 284/292 or something. But all in all this motor should be a easy 500 just how high is the question.

 

500 hp out of a carberated stoker chevy is pretty common now a days dude! Come on.
The weight is in the heads--and I know those will be aluminum?
Dry sump system?
What are you going to do with the chassis/rear end?

 

I put a 350 LT1 in a Porsche 928 several years ago. Factory FI ally manifold with stainless headers. Weight as installed with ally adapter, alternator, AC compressor & PS pump was 630 lbs, about 5 lbs lighter then the ally Porsche V8 it replaced. Thats what, about 350 lbs more then the dressed Renesis?

After selling the 928 I never expected to own another touring class car that drove as well. The RX8 changed that. While it doesn't have the stump pulling torque and is a little more thirtsy on the highway its a much more fun to drive car.

The LT1 was stock internally and delivered an honest 24 MPG at 70-75 MPH. City wasn't so good, probably because I just couldn't avoid driving it miserly. Anywhere from 12 - 15 MPG average on city driving.

I think if I were to do a conversion on the RX8 it would be a turbo 4. Good luck on the V8 adventure its sounds pretty cool.

 

As far as the dry sump... I've been looking into that!!! Hadn't decided the route yet as far as that.

As far as the rear end I use to put 400 whp to it and it held up find and never had a problem. I don't plan to drag race it. If I do it will be just a day worth of fun. But I'm hoping the rear end will hold up.

 

Ok. I was wrong. I should have researched before saying anything. I didn't think a 383 stroker made power like that and it's cheap. Cam specs look close to one that did almost 530hp with 1 3/4" headers


This setup is good for 425 to the wheels? Is that the goal?

 

There really isn't a exact goal really.....and like was said...The heads hold all the weight. A stock head with cam can get ya as high as like 375-400 hp.

But my heads well are 220cc in the intake and like 180 or 190 in the exhaust. compared to your stock head of like 170 intake.

Setting the stock head beside the new one. The new one is almost a inch taller. Since it's taller it have a lot larger intake and exhaust hole. The huge cam... the air gap intake with a double feed, and double pump carb. This thing should be nuts.

I'm running an adjustable distributor as well. So I'll be able to tweak my timing curve as well.

As some say carb is old history. But carb with new technology is killer. Tuned to perfection. In this case a adjust in fuel pressure will adjust my wot fuel ratio. While my screws will adjust the idle.

 

i miss the carb! A lot.
New tech with carbs is crazy---it still doesnt give you the fine tuning as injectors do but hell --who needs fine tuning for the street with power like this!
What kind of intake will this badboy have? Single or dual plane?
Havent answered my ? about the chassis?
cross that bridge when you get there railroad man?

 

Well yeah not fine tuned...for every RPM but you can tune pretty good with them.
I'll be running the Edelbrock air gap p/n 7501 it's a dual plane...since I'm still on the street dual is better. As far as the chassis I said I stuck 400 to it before. I'm just hoping it holds up pretty well.


Anyways on to another note... I'm still waiting on my main bolts so I can't build the bottom end of the motor....and I'm waiting on my other head..and the damn cam kit. But otherwise my engine is ready to be built. I'm going to build my own oil pan for clearance reasons. I want to keep it up off of the ground as much as possible. I'm making it wide rather then deep so I'll end up with a 8 qt or so oil pan. Who knows I may just go 10 quarts.

Oh and my transmission come in tomorrow. But with my th 350 bolted to the bock to see my angles and get the engine sitting where it needs to be.. here is a idea of what it's going to look like with a high rise intake.

 

maybe you need a fabrication mock up block and trans for fitting purposes?
The carburetor will make the drive ability and tuning a whole lot easier --never mind the oem puter.
How are you going to do the steering?
Sorry dude--i have too many questions
But following this trend.........!
Dont forget the increase in TQ --that may be a big difference from the engine you had before.
TQ can bend things---ask me how I know
