Hi, im new to the forum and was just wondering if some people could help me choose parts for a good strong 383 stroker. The motor will be going in an 83 z28 shell that i picked up a few days ago. I have about 3,500 dollars saved up for the build so far and i already have a block (350 4 bolt main with standard bore) but no crank, heads, pistons etc. Im trying to stay on a budget but if i have to wait and save up more money to have good brand name parts that are reliable i will. I dont want to have cheap chinese parts in my american car, so most things on ebay are out of the question. So please, any good ideas on this build will help me out alot. Im looking for aluminum or vortec heads and preferably a forged crank and pistons. And also a good cam for it. I want it to be a good street/strip car so im hoping to get around 450-500 hp/tq. All suggestions are greatly appreciated

 

For $3500 that will mean you will be using a lot of used parts for that HP and Torque. The block you have what year is it? Because that will help on the exact kit that will need to be purchased. With the back of the motor facing you look on top of the motor to the left of the center bolt for the transmission. What are the numbers there?

 

Minus the machine work, your goal is somewhat reasonable as long as you have all the front end accessories already. A scat rotating assembly is capable of handling the power you are looking to make and is under a grand. Edelbrock actually has a top end kit for strokers, they claim 460 horse 460 ft lbs on like 9:1 compression. The kit costs like $2400?

 

The block casting is 14010207. And I was searching for edelbrock top end kits and found this one on jegs for $2,000 (http://www.jegs.com/i/Edelbrock/350/608919K/10002/-1). It doesnt have the cam or timing set like the others but its fine cause i want to get the cam last since i want it to work good with everything else. I was also looking at the scat rotating assemblys and found this forged kit for $1,800 http://www.jegs.com/i/Scat/942/1-407...0002/-1?CT=999). I know buying these 2 things will be using more then the $3,500 i have saved, but if i have to save up say another $1,500 or so to build this motor right i will. I dont want junk parts, everything is gonna be new on this motor.

 

Does your engine have a 2-piece rear main? If not that kit will not work.

if it does for $49.99 more you can get this kit with H-beam rods for greater strength. http://www.summitracing.com/parts/SCA-1-40760BI-60/

 

Yeah it does have a 2 piece. And what do you think about these stroker kits? Its around $1,200-$1,600 for the kits depending on pistons (http://www.strokerkits.com/index.php...emart&Itemid=1)

 

They don't list who's making the crank and rods. Here is a Scat forged kit through Summit that's only $1307.98 http://www.summitracing.com/parts/SCA-1-40755/

 

Although not necessarily cheap, Scat is Chinese. Eagle too.
Check out Howards. 100% sourced, forged and machined in the U.S. (Their website isn't very good though)

Or Competition Products.They distribute Howards components among others.

Im a big fan of eagle products.. as far as the top end your looking at do some research on the different top end combo's out there.. or sit down and piece together one yourself. For a 383 personally i wouldnt want anything less than a 200cc intake runner. Dart and AFR have good choices... Then once you select the heads you want.. and have the flow numbers, go to comp cams site and download thier cam help program.. it gives you alot of different option to choice from.. granted if all were perfect in the world and ya had every spec you could use.. i compared desktop dyno to a real world dyno and came out only 1 hp off..this was on a nascar engine..so i had every spec i needed. so get something like desktop dyno and play around with some different combos then build ya a tire burning nightmare

 

I have a Scat stroker kit. I don't see anything that says made in China anywhere. If it is made outside of the USA it has to be marked with the country of origin.

 

What transmission are you planning to have behind it? That is part of your cost. Adapters ect. Might want to check that out first. Speaking from very recent experience on my part. The wrong 383 kit lead to a fly wheel that didn't fit, a custom bell housing having to be bought. Redoing the kind of clutch I have, all to handle my "good deal on a 383" motor. Your probably smarter than me and already know this but just throwing it out there in case.

 

The raw forgings are sourced off shore. It used to be China but reports have it that they now buy from India. The machining and treatment process is done in the US. That's why Scat doesn't say "Made in the USA" on their packagaing or in their advertising. Nothing wrong with a Scat crank as I see that they're recommended and used by hundreds of individuals and teams.
However they are still an off shore item.

Totally clueless.
The OP wants 450 hp and 500 ft-lbs. For that, any head over 180 cc is too much. And DD2K has never once predicted the real results that I get from a real dyno, to within 5%. You might've got 1 combo close once, but notice it was Nascar, not a real street combo.

 

Sometimes hard to find kits that give the parts and compression you want. Most flat top pistons will give 11 to 1 compression which is good but use a good aluminum head for pump gas compatibility. I wouldnt use a vortec iron head on the motor. 3500 probably wont get you anywhere near a complete motor with forged internals unless you shop around and find used deals. May have to piece together a kit to get the components you need.

I used eagle forged rods/crank with SRP flat tops in my 383 and after block machining and such plus price of block, it was more like 3600 for the shortblock. Then add 1400 dollar heads, 300 dollar cam, 120 lifters, 200 dollar oil pan, etc etc and it starts adding up quickly. If you build up the block yourself, you save abit more. I had a shop put it together so thats abit more labor.

My setup probably had abit more power than what your looking for. AFR 195's with 230/245 hydraulic roller. Stealth ram fuel injection up top, mildly ported. About 400whp thru the automatic, was a mid 11 second car. Very streetable and ran well on pump gas.

Dont need forged internals for that build but I also ran nitrous later on, so I went all forged for strength. Plus I was turning 6800 rpms so its nice to have strong rods.

My new motor uses Callies Compstar crank and rods. Forged over in china, but final machining and quality inspections are done here in the USA. Seem like nice components, and price is near same as Eagle forged stuff.

 

i dont know bout 450-500 hp for that but i made around 425hp for less than 4k. my trick was was an eagle cast crank and i beam rods with iron heads. down side is i only spin my motor 6000 rpms and i know it would like to see more. its fun enough to make a 3700lb car run high 12's.

 

if you are looking to make that kinda power on a budget i would build a 406

 

406s aren't budget unless you score a free block that isn't already 30 over, isn't 4-bolt-main, and isn't cracked.

 

i should have worded that different . the 4k would produce more in a 406 still getting into crank and pistons. 400 are getting to be harder to come by. I have been buying everyone i could for the past 10 years. but they are out there. just watch out for the coreshift
