Thread: Scat or Eagle?

Tweet

Looking to get the most bang for my buck so what is your opinion on who has the best kit to build a 496 stroker and does it really matter which crank for a purely street driven tire smoker? Who has the best prices as well? Thanks in advance for everyones input....

If it is just a street car a cast-steel is fine.
They will both vary some.
I have used both the Eagle cast-steel crank and the Scat cast steel crank up to the 500hp mark with-out any problems.
I would look at the Speed - Pro Pistons Hyper pistons.

i have built them low buck 496 with the speed pro hyper pistons stock rod with cast steel crank and some with the 4130 forged steel i had good luck with the scat.the nice thing about the cast steel is you do not have to run the H bearings on the cast crank

Good call Pat.
I forgot about the bearings.

How about Keith Black pistons? Anything I should avoid?

I rather go with Scat because I've seen Eagle spec is too for out and having to redo it to bring in with spec. That sometime rods bore too tight os crank too big.

I think the Speed Pro pistons are better.
In a claimer engine about five years ago the KB's piston top use to break off right above the top ring land.

I have seen both of them far out of spec.
That is when you send them back and ask for a different crank.
I did have one customer that bought his crank used and by the time he was done he spent about $300 in balancing the crank.

Why don't you just use a stock forged 454 crank?You are giving up a tremendous amount of quality to use a lesser quality piece in either the eagle or scat

You won't have 496 inches but you can go to 481 with readily available stuff.
I wouldn't stroke it further unless I wanted to get up to 540. Used to do several 522 with stock 4.0 stock forged cranks at 4.560 bore in the bow tie block. One of my favorite combos was the 4 in stroke at 4.280, 4.310, 4.350 and 4.375

We ran a 460 in(4.280 ) in a truck block( 400 tall deck) in my Monza in the 8.0s at 169+ mph ( lotta 8.02s) but never got into sevens or over 170 with it--it had stock c exhaust port alum heads, 454 ch pistons, 400 long rods, touch of NOS.

It was a pretty economical buid as far as components

Jerry,I am guessing he has a low-deck 454 block.

Erik--I wasn't suggesting a tall deck, just stating what I had done with one, I could of used a shorter ch custom piston and longer rod but used a 427 truck core including the oil pan , and production 454 12/1 cr forged pistons from trw or speed pro. one of the biggest things was adapting a distributor because of the plates between heads/manifold raising it

I see.
I do like the 535 in a tall deck block with it's long stroke for street cars.
With the "slip collar" on the MSD dist. it has become a lot easier of the years.

the stuff is not as bad as you think and is a cheap way to go built over 12 of just the 496 about six or so with the 4130 crank and the tall deck truck block with a scat 4.500 crank for a air boat the short deck headers will fit and you do not need a slip collar or spacers of the intake

i just sold a bow tie 9.800 block on e-bay that would of got him a 565 i have more

Pat, are all the tall deck intakes machined down to except the std. sbc/bbc distrubutor?
