Yes they get expensive. If you had actually built that motor you would be looking a another couple of thousand just for the small stuff.

I know I have been caught years ago looking at a rotating assembly for say 2 grand and heads for 1 grand or so then add in the machine work on an OEM block and figure this motor is going to cost me 4-5 grand....well when it's actually done and in your car you spent 8-9 grand

If anyone wants a big inch small block I would tell them to build a 406ci, less expensive and you don't have to clearance the block in most cases

Tried that for a friend (408). Still spent about 10k on it, that was with me passing on a pretty good discount on machining and parts I get through my machinist and me doing ungodly amounts of porting and blockwork for beans as a favor. Of course only 2 others gave ballpark est of 15k+...with all the extras and "what abouts" we added it would have reached 18-20k easy.

There are ways to do it for less no doubt depends on how youre going to use it.
About 6 yrs ago I decided to change cams add a touch of compression and go solid on my 350. 3 yrs and 12k later I had it.

so, my qeustion was simply, how much was you block? i wanted to know how much it was for your engine to be so expensive. also, i did all the work myself, so i didnt add labor costs

My first 383 stroker was done with all good parts. $3200 something for just the rotating kit from Flatlander racing. $2000 in cam and Valve train parts. $2000 in heads

I don't know anyone that shops around and gets great deals more than Wayne (Motorhead), and as he has stated, he built it and didn't pay someone for the work.

thats cool. but i do know what some people pay and i know what i saved by shopping around. "YOU GET WHAT YOU PAY FOR", isnt always true. i have top of the line parts. i just did my homework. i am fully aware that a lot of people love to buy the best, and brag how much they spend. im not knocking the guy, his engine looks awesome. but dont knock me for being thrifty! if you want to spend a lot of dough, there are tons of suppliers out there that will take your money.
thats an awesome engine, but i feel for the guy if he spent that much cash. its awesome but its not like its a blower motor or turbo motor. plus its a chevy! do you know how cheap chevy's are to build compared to other makes?? DO YOUR RESEARCH MY FRIEND, and try to build a ford or a dodge engine. then ill see 15 grand and understand why!

what is with you guys??
you can get a 383 short block with forged internals and all the work completed for 1800 bucks, anywhere! SB chevy AFR's only cost 1200! you can even put in a roller cam for a around 800, a regular cam costs 300 with lifters! you can get roller rockers for 150, the expensive ones are only 300. an airgap is only 200. carbs usually go between 200 and 400 depending on size and type. and you can save even more if you used iron heads and off brands.

Where would a guy buy a Complete 383 short block fully forged for $1800. The rotating assembly is more than that and that is a cheap one.

That is $7200 before machine work, gaskets, studs, block intake carb, headers, Ect. This is more realistic. $4000 buys you junk parts.

The same engine!!!!!! Dude, it is not the same if it is built with chinese crap.
I just built a 383 with a stock L82 block. AFR heads, Full roller, fully ARP studded, forged. Got over $7000 in the long block. Add in intake, exhaust, accessories. Motorhead is spot on on the cost to build an engine with the power his has that will hold together. No way to build a quality Forged 383 for under $4000.

if you say so. i did it. so can you

you can get a 383 short block with all forged internals, complete for 1800, anywhere. and its not with chinese crap. at least mine isnt.
and like i said before, it ran a best of 11.40, and has stayed together for the last two yrs. under 4 grand. maybe more if i include the coated headers, k&n filter top aircleaner, fancy chrome hose clamps. whats with all the negative waves for a job well done? not a lot of positive folks here.

ok. the place i got mine has gone up over the last two yrs. but the same short block they sold me now goes for 2100. i paid 1800.
just did a quick search on the net. found some that are uber expensive, but found several ( 383 short blocks ) that were even cheaper than mine! found several different versions on one site, starting at 1400. there are so many i cant list them all. just search and youll find deals like i did.

Good thread the Rich verses the Thrifty lol.

You can tell people all day long till you are blue in the face that you can build HP on a low budget if you are willing to do some work. But they will not believe you. I have tried on this forum as well as a few others. For HP on the cheap go BIG BLOCK. With a BIG BLOCK you can build a reliable engine that makes from 550HP to 650HP for $3000.oo more or less.

a lot of folks suffer from THINKING that they have to have the best of everything. i see guys at the strip all the time that have cars that are falling apart and look like junk and go and set low E.T.! happens all the time. a friend of mine races pro mod mustangs and he tells a funny story about some guys he met at a machine shop where he was flowing his heads. these guys come in with some knarled up heads that they had ported themselves, high as a kite! he swears that they flowed better than his big buck heads with all the cnc machinening.

tell me, how do the guys in that stock class run 9's with all stock engines? wasnt the fastest guy last yr. in a c3? all stock, bias ply tires, no super mega expensive parts. 9's!

i have also tried to tell this forum things can be done cheaply and " down home " but get the same responses. but its a forum full of rich corvette guys that know it all. nobody ever believed me when i told the story about my brothers and i reguarly turning 7-7500 rpms for a whole race season, in a 2 bolt main, 2 barrel, 350 on a dirt track. the only thing we could change was the cam. of course we ported everything to death, but my point is it can be done.

i wonder how many guys buy stuff just to say theve got them?

Not everyone is rich here. All my cars have over 100k on them ,I do my own ***'y, porting, etc in order to afford it. Sure you can work stock stuff, may last may not. When Im taching it out I dont want to worry about it so it gets a bit "overbuilt" so the possibility of doing it twice lessens as much as possible.

What so many forget to include on their build costs is the little stuf..Gaskets, bolt kits, tin, etc etc. That stuff adds up. Most shortblocks Ive seen dont have timing chains, oil pump. cam lifters, pushrods, rockers, etc. Or they offer an assembled one with junk stuff (no name given). Thats risky to me if youre going to twist it or throw power adders to it.
Weekend cruiser different story.

I am definetly not rich. I have over 2 years in my Engine build doing a little at a time as I could put the $ together. I do know if you want big power that will hold together you have to use quality parts and pay attention to every detail no matter how small. But I also here a lot of BS on the forum. The OP stated you can buy a forged 383 short block with no chinese crap for $1800 anywhere. I just want a link to it. Asked 3 times no link.

http://www.fastraces.org/ These are Factory appearing stock tire cars. Just getting into the 10's. Appearences can be deceiving. These are not stock. They are full blown race engines in a factory appearing package. Here is a quote from there rules
:2.04 Internal engine modifications OK.
These guys all have a ton of $ in there cars. The ones that are competitive have tens of thousands of dollars of modifications throughout the car and they are a long way from 9's. More BS
http://www.fastraces.org/members/fas...5!OpenDocument


I have no issues with saving some coin when building your car. I do it as often as possible. I also admire the guys with a full machine shop, machinist tools and the knowledge at their disposal that can do all the required work themselves to save a bunch of money. Those tools cost money and lots of it. But buying a short block cheap and bolting a bunch of off brand parts on to it in no way resembles what Motorhead or Gkull did. Original post was.

This isn't even the small parts. My latest Callies crank was $2000 at cost because I didn't want it to break like the last one.

I've said it before, by the time you add all that valvetrain stuff up you could have got a shaft system for another 100 bucks

I'm not rich either, I surf the net every day looking for deals. My buddy who owns a engine shop cuts me good deals and this new motor of mine wouldn't have happened if I didn't get some cash for my 406ci. Speaking of cash, that's all I use, if I don't have the cash I can't afford it
