    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.
    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.

    I like Callies but at your hp you really don't need it plus they start at $900.

    I think an early 350 block with the splayed caps would be all right.

    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!!!!!!
