I'm looking to build a 383 stroker, and I'm going to buy one of the crankshaft/piston/h-beam rod kits. I saw a Scat kit for $450 and I thought tht wasn't too bad. I want to buy an affordable qaulity product what brand should I choose.

I got an Eagle rotating assembly for $750, it went over 500 passes in the mid ten's with no problem. I freshened up the engine for this season and got the same kit again and now how over 100 passes on this set up turning the same e.t.'s with no problems. Just dyno'd it at 491hp at the wheels with a 2 bolt main.

whats the torque??

dam pretty good do you know the part number for that eagle kit you got?

Make sure the balancer for the Eagle kit is sfi certified. I bought 2 Eagle cranks last year and my machineist wouldn't use them. The snout was .002 too small. There for no pressed fit for the balancer. sbc should be a pressed fit for the balancer. I called eagle direct when I got the second crank and it was in their spec. and they said they use a pioneer balancer with their kits. Only thing is the part number they gave me is NOT sfi certified. I switched to scat cranks, they measure right on the money.

hey are you still running tpi or going to a carb setup

allenfre

. I also want to know. I am hoping to see an awesome carb setup

Just out of curiosity how much does stroking a 350 cost in machine shop costs alone??

85z28guy

Depends on shops and locations. The only extra machining needed is some clearance for the rods. You also might have to run a small base circle cam depending on the specs of the cam. I ran a scat kit with kb forged pistons, I wouldn't use there bottom line kit as its designed for claimer series racing.

I have found that cnc-motorsports seems to have the best prices on balanced rotating assemblies, I would look them up before you buy.I would not bother using h beam rods with a cast crank and hyper piston, scat makes an I beam rod that will handle way more power than the cast crank.

I just saw Whites Performance advertising on Ebay a balanced Eagle stroker kit in the 6-700 price range. There in Kingsport Tn, so you could drive up and check them out.

i might do that on a free weekend thanks

they had sum pretty gud deals on there and im pretty sure thats where my machine shop ordered from
my rotating assembly was 600 shiped
cast steel crank, sir ibeam rods, and hyper pistons

Wow that great for a two bolt block. What kind of trans you running & what rpm you leave at.

samiam91RS

wow! those are good numbers! you must have a nasty cam in there im thinking at least .500?

Im running a SCAT kit.Forged stroker crank,forged h beams in 6.0 inch,and mahle forged .060 pistons with free floater wrist pins.complete kit was about 1700 bucks.had to do alot of clearencing in the block for the rods and cranks but it was well worth it.Made 628 hp with 570 ft. lbs on the dyno,i shot it with a 500 hp pro fogger and it took the beating.Im completely satisfied so far

samiam91RS

just askin here for all you stroker guys.

but someone told me that a stroker doesnt see a long life, due to the high stress on the piston/rod angles and that the bearings wear down FAST and that they dont see more than 50k miles, usually. not talking about the beating of drag racing but mostly street drivers.

is this true?

camaro1185

Well im not a stroker guy...yet. i hope to build one one of these day, so im also interested in your question. I think the reason they may not see more than 50K is becasue the engines are usually built to be beat on/raced, therefore they spend lots of time at high rpms, which puts lots of stress on the internals. I think that if you had a stroker that was built well with quality parts, and it was just used on the street, i dont see why i couldnt go 100k.

No it's not true. The type of stresses and wear you're talking about come from high rpm use. Strokers make great daily drivers; with the added torque, you won't rev them as high as a stock cube motor with comparable hp.

http://www.ohiocrank.com/chevsb_rotate.html look at these kits. i would add forged pistons no matter what u are trying to achieve.

stroker when built well, doesnt sacerfice as much reliability as some may claim. a well ballanced and light rotating assembley wont woller out the bores from excessive side load like some of the ford 347 strokers do.
generally an engine built for racing is gone through long before 50k miles.

and for premature bearing wear, i dont see why they would say that.

dirtracer43

a 383 will last a good while on the street with no abnormal wear on the bearings. i had a circle track 383 pushing 700hp blow on me last year beacuse of oil starvation but that motor was regularly ran at 7500 rpm and the lowest it saw during a race was 6400

I have an eagle 383 kit and like it a lot.

Don't waste money on a balanced kit. Get it balanced yourself. I got the balanced kit when I built mine and while talking to my machine shop about my built he told me that he has had to rebalance several Eagle cranks. I bought crank, rods, pistons and rings as a balanced assy. I watched this guy check my balanced assy and it was way out. It cost me less to get rebalanced than I paid extra to have a balanced assy.

Here is the 383 setup that I built:

350 4 bolt main roller block bored .030" over
Forged Eagle one piece rear main seal crank
Clevite "H" series main and rod bearings
Scat I-beam forged rods(bushed)
Wiseco Pro Tru Forged piston kit with plasma moly rings (10.7:1 CR)
Stock oil pump
CompCams XR282HR-10 cam
Pete Jackson gear drive
ATI Super Damper
2 pc timing cover
Chrome oil pan
AFR 195 Eliminators
Stock roller lifters and pushrods
Crane Gold Race 1.6 ratio roller rocker arms
SLP 1 3/4" headers
Mezeire electric water pump
Accel SR intake and Edelbrock high flo base with FMS 30# inj
150 shot NOS

I'm sorry, I got carried away. I had the kit balanced at a local machine shop. I have a little over 500 miles already on this motor(PITA to tune) and I must say that I'm very happy with this combination. I can really tell the difference between this motor and the 305 I had in there before I set the rev limiter(Nitrous Mastermind) to 6500rpm and so far the T5 has survived.

camaro1185

Looks very similar to the build im currently pricing out. What kind of numbers is that setup putting out? if you dont mind me asking, what did it cost you for that build including the machine work/balancing/tune?

pwdbychevy

I'm not sure on the power numbers but I'm guesstimating around 500hp at the flywheel w/o the NOS. I raced one of those Mustang GT500 during my break-in period(I couldn't help it, he started it!) and won by 2 car lengths. Imagine if I would've sprayed! The Mustang runs 12.9 in the qtr so mine is definitely a 12 sec car. As far as price goes:

350 4 bolt main roller block bored .030" over, notched and rotating assy' bal - $750
Forged Eagle one piece rear main seal crank - $459
Clevite "H" series main and rod bearings - $106
Scat I-beam forged rods 6.0"(bushed) - $209
Wiseco Pro Tru Forged piston kit with plasma moly rings (10.7:1 CR) - $450
Stock oil pump - $40
CompCams XR282HR-10 cam - $200
Pete Jackson gear drive - $250
ATI Super Damper - used $205
2 pc timing cover - $40
Chrome oil pan - $60
AFR 195 Eliminators - $1440
Stock roller lifters and pushrods
Crane Gold Race 1.6 ratio roller rocker arms - $350
SLP 1 3/4" headers - $500 slightly used and coated
Mezeire electric water pump - $325
Accel SR intake and Edelbrock high flo base with FMS 30# inj - $850
150 shot NOS - $500
Spanking a GT500 - PRICELESS!
