Which 383 stroker kit is the best?
Im currently building a 383 stroker and am not sure which rotating assembly to purchase. Ive heard good things about eagle but the scat assemblys claim to be stronger. The motor will be for street/strip (about 10.5:1 comp, 450hp/450tq) with a possible 150 shot of juice later on. I know i want SRP forged pistons and total seal gapless rings but am not sure on the eagle cast crank/ SIR I beam rod package or the scat cast crank/4140 rods. Scat claims their rods are better/stronger than the 5140 eagle I beams however ive heard many people say eagle is the best. Any experience or advice would be great as i cant wait to shred through some hefty meats!! Thanks, Eric

ive seen scat cranks and rods break in half and the rods bend like a corkscrew doesnt seem like you'd need after market rods to go to 450 horse though....
Well they are both import brands.Originally Posted by 70_"SuperNOVA"
I have never seen either a Scat or an Eagle assembly break.
If you are worried about it run a 4340 assembly.
In the engines I build if I get close to 750 on a sbc or about 900 hp on a bbc I
will try and buy American.
that is the same here to .i have seen the scat take alot never see a scat forged crank brake in 1/2 have seen them crack but that was in a hill climber 548 cid in a 4000 truck that seen the hi side of 7500 all the time up a hill .i fix a 632 that busted out the oil pan rail and cut the rod in half. kickout two lower parts of the bore on a world block i sleeved 3 holes welded the oil rail up and the crank was welded two new rods the two piston still running that was a cat crankOriginally Posted by erik erikson
i know 450 hp isnt all that much but if i decide to put a 200 shot, id like the extra insurance. What american brands would you suggest?
I like Callies but at your hp you really don't need it plus they start at $900.Originally Posted by 70_"SuperNOVA"
i would look at a better block if not plug the deck and stud the bottom end with billet steel caps i would run the H beams with 4340 import scat crank and rods usa parts crank and rods howards .crower
i let you know if i still like callies? order my crank 3/25/07 still not hereOriginally Posted by erik erikson
I think an early 350 block with the splayed caps would be all right.Originally Posted by pat mccarthy

You mean they did'nt just have one lying around.L.O.L.
small 5.500Originally Posted by erik erikson
Hey Pat will that fit in a "low deck" block???Originally Posted by pat mccarthy
yes you need a very short rodi hope it fits in my block cam may be tigth
Just take your grinder and cut some of those funny bump things off the cam, it'll fit just fine and probably run better, too!!!!!!Originally Posted by pat mccarthy
