383 Stroker Kit? Need Opinion
 
Hey Guys! I am new to the site and just joined a few minutes ago. I got a question for you guys out there.

I have rebuilt a couple Chevy stock 350's before but never actually built a "performance" motor. I'm planning on building a 383 stroker motor here soon and I have been going nuts with all the parts and options out there for it. I'm starting with a 350 4 bolt main block that I will have decked and line honed and everything else done to it so it will be perfect. It will also be bored .030 out also. What I want to accomplish with the motor is to try to get it between 450 to 500 HP on pump gas. I'm not planning on put NOS or a blower on it or anything like that. I just want a to build a nice clean motor with good power.

Now this is my question for you guys. I was scanning through ebay and came across this 383 stroker kit and I would just like to get your guys opinion on it whether you think its a good kit or more of a waste of money or worth actually buying or not. Here is the address for it.

SBC Chevy Scat 383 Rotating Assembly Forged 030 Pistons H Beam Rods ft 2pc RMS | eBay ---This is the link. If you copy and paste it, it should take you to the kit.

Just let me know if you think it worth buying this or not. I have asked the guy a few questions about it but would rather hear from some actually guys not trying to sell it. Thanks guys and any info and opinions are greatly appreciated.

I've read good reviews for SCAT products, and have also heard good and bad early on views for Eagle kits, I've heard they cleaned up their act, I have a forged Eagle setup in my blown Nova, it came in at spec. I assume this kit comes with forged SCAT rods? What brand pistons?

Seems everyone lately wants 500 hp on pump gas, most on a budget, like it's an everyday gimme...and want it streetable NA. It can be done, but it's a tall order.

Looks like a good kit for the money, the piston rings are on the thick side, the the balancer and flexplate may be questionable but for a hot street engine with a 6,000 rpm redline that kit should work well.

The parts aren't high end stuff but they are very good durable pieces.

vinniekq2 06-25-2013 12:18 PM

decide whats most important.max power or max reliability?the budget will determine where the money gets spent.
My 434 is 10 years running,but it wasnt cheap and it makes decent power.... choose the heads first,,,,thats where the HP is released,,,
when you have chosen the heads,repost and see whats left in the budget.500 hp needs a head that flows 270 CFM intake side with 75% of that on the exhaust side.You can do it with lesser heads but will take better planning of parts and maybe more RPM

SGreve32x 06-25-2013 12:30 PM

Well, to be honest, I'm not totally set on which heads I am planning on getting for sure yet. I don't want cheap parts but I am working on a budget in this engine build also.

The heads that I have been looking at are the Dart SHP Aluminum Heads and the Motown 220 Cast Iron heads.

The cam I plan on using is a Comp Cam Xtreme engery cam that is a Hydraulic Rolller tappet with hydraulic roller lifters. The cam is a .562 Exhaust and a .540 Intake.

vinniekq2 06-25-2013 12:48 PM

why not use the shp heads and roller cam in a 350?
220 heads flow a fair amount for higher RPM or bigger engine. what are the flow numberson the 220s? SHP heads can support 450 HP before porting

Why not use a 350? To be honest, I don't want to, lol. I want a 383 stroker engine.

I'm not sure what the flow numbers are on the 220's. I haven't got that far ahead yet, lol. I'm trying to get the motor in the 450 to 500 hp range.

ap72 06-25-2013 01:06 PM

you can hit that range with a stock 350 short block and a good cam and top end. I wouldn't look at the Motown 220's. Id use the Assault chinese heads before those. the SHP's arent bad, nor are the Summit or Jegs "house label" heads. The Jeg's heads are actually really good.

Nothing wrong with a 383 but if your budget is limited make damn sure you get a good set of heads first, along with a good carb, intake, ignition, cam, and valvetrain. If you have enough for all of that then go with a 383. Don't cheap out on the top end! I'd also consider going EFI before going with a 383 for a street car- it makes a HUGE difference on a car that will see a lot of driving.

vinniekq2 06-25-2013 01:08 PM

you pick the heads BEFORE the pistons. 220 cc intake runners are big.My intake runners are only 227 ccs on my 434

SGreve32x 06-25-2013 01:22 PM

I wouldn't really say my budget is limited. I just don't want to dump 10 grand in a motor. I'm not gonna buy low end parts for this motor.

To be honest, I'm not even sure if that kit I have listed is what I will be using. I was just seeing what the opinions were on that kit. I have also been looking at a Scat forged crank with Mahle forged aluminum pistons. The motor will be a 383 stroker for sure. That's about the only thing I am 100% certain on at this very minute.

The cam and intake I am pretty certain on also which is the Comp Cam Xtreme Energy and the intake will be Edelbrock RPM Air Gap intake.

vinniekq2 06-25-2013 01:30 PM

ok,decide what heads you will buy. Then decide what parts match.the horse power is in the heads with correct cam and DCR.for a DD 195 CC heads might be better,you decide what fits your situation.10k for a good engine is a fair price.not many 5k engines make that kind of power.
2k for a kit and balancing,2k for heads,close to a k for machine work,,,,,

Voted most likely to frag itself.

This strikes me as a very nice kit, really good parts. The only nit I could generate is the use of 2618 alloy pistons rather than 4032. The 2618 is killer race stuff that requires a pretty loose skirt clearance, great for racing after you warm the engine but noisy and oil consumptive if you don't warm the engine up first which is a PIA on the street vehicle. The strength of the 2618 material is well above that of the crank and rods which are plenty sufficient. The 4032 high silicon gives up a little ultimate strength to the 2618 but is at overkill for a street motor just like the 2618 just not as much overkill. The advantage of 4032 is a much tighter skirt clearance which keeps the rings squared up with the bore even when cold which improves compresson sealing, reduces oil consumption and skirt click noise. But if you know about 2618's need to come up to temp going in and plan to operate the motor with a decent warm up they'll work just fine. A hint I'll drop for street use would be an engine oil to engine coolant heat exchanger (all modern OEMs use this in some form) this really reduces warm up time, getting dimensions stabilized quite quickly.

I have heard nothing but good things about these cams. I have a couple friends that actually have them and they recommend them.

vinniekq2 06-25-2013 02:49 PM

all cams are good or bad,they have to match the application.Buying a cam before the heads is just plain wrong
