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.Quote:

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.Quote:

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.Quote:

I have seen both of them far out of spec.Quote:

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.Quote:

I see.Quote:

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 intakeQuote:

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

I prefer Scat to Eagle cranks for 2 reasons. The Eagle forged units are cross-drilled while the Scat ones aren't. Plus, Eagle's machining leaves a lot to be desired. I have had to turn most of the Eagle cranks to correct the taper and hour-glass shape on the journals. Scat's machining is very good. With either's rods, I always re-lube and re-stretch the fasteners. I find that they are generally not stretched enough out-of-the-box. Usually they need some honing to make them round after that.
While you don't need the H-type bearings with the cast cranks, I run them anyway. I find that many times the journal radii taper runs out pretty far away from the fillet. The H-type bearings give a little more edge clearance in that area.
I prefer the ACL race bearings. I get them from Engine Pro, they are the Engine Pro brand of race bearing. The price is right and the quality seems better than Clevite lately.
I think the 496 build for the BBC is a great idea. It is not terribly pricey, block clearancing is usually unnecessary. I gives good power and doesn't require a lot of head to get it.

yep all the scat stuff i have used i just had one crank that i had to send back was one 4340 that look like it was polish with 80 grit .i run the tq up and down on the rods then touch them up on the sunnen hone .i do not care for the housing bore size on the rods on the big end of the spec i like hi crush.i like king over clevite never tried the ACL H bearings or engine pro i just may they seam good but the kings are more to size then the clevites. i like the speed pros with the 3/4 main but the size is all over the map and so is the tapper
