Scat is not cross drilled and is the one I am going to use on the next build! I am talking Forged. |

Eagle has spotty quality control, I would sooner run Scat.
Seen too many guys have issues with out of spec measurements not outright failures. |

Have had the same issues with scat (VW's)... When it comes to some of the lower line (china) products these things happen..
If we could assume that all parts were correct based on how much was spent for it there would be no need to check any clearance in the motor.. but I'm afraid thats not the case... _________________ http://www.dtpprecisionrebuilding.com |

One more thing, I have had a 460 ford eagle crank that had a throw that was off .010 too.. But I could ramble on about some bad scat stuff as well..
It is what it is, and thats better then stock cast... _________________ http://www.dtpprecisionrebuilding.com |

I think you'll be surprised what a crank will handle.
My old 352 nitrous motor had a standard GM steel crank & stock 010 4 bolt block with cast caps & saw 8800rpm every run.
The rest of the engine was as follows: Venolia nitrous pistons (14.0:1cr), Manley 6" rods, Brodix -8 heads, Crane 1.6 rollers & girdle, Erson roller cam, Victor Ram with twin 660 c/s carbs, NOS Pro Shot Fogger & modified NOS Cheater plates running a total of 350 gain. The nitrous was activated when the transbrake was released. It had full MSD ignition & a Comp Cams belt drive setup for the cam.
I ran a manual glide with brake, 6200 stall & 9". Rear wheels were Pro Stars with 32x14-15 slicks.
This motor pulled 8800 every run & 8000 in the burnouts with full 350hp nitrous shot.
It used to blow the centre 4 bolt cap in half on the odd occasion but never actually let go.
The result: 1.26 60ft, 9.08 @ 140mph over the 1/4 in a 2742lb door car.
So dont underestimate factory parts. |
