I guess it's that time of year.

Want to do one of these 4.125" Crank motors with a 6,300 SBC journal rod. Maybe I'll luck up and find another virgin 340 block to work from...they're getting rarer and rarer....would LOVE to do one of the Siamese 4.18-4.22 bore 340 blocks, maybe if I get enough coin.

This is not to replace the 414 in the Rocky, Ijust need to get something on the stand since the weather's getting a bit cooler.

sold one of my W5 top ends, but I still have 1 good head, 1 not so good head, and 1/2 a head cut up, couple of intakes, and a set of iron rocker arms. Also have a 340 block that will clean up at .030, but it didn't sonic well in one hole for any serious power. Need anything?

@J body,

Thanks buddy, I can sure let you know. Ideally, I'd like to find a top end already machined properly, the W5 stuff really doesn't seem to be too hard to get a hold of.

Doing the math with a 4.22" bore Siamese block and a 4.25" BPE crank that'd be right at 476 cubes.

Hey, where did you come about a 1/2 head Guess the W5 thing is over for both of us.

You get to a point of diminishing returns will all those inches on a "small head" in a hurry.
My old 422 with w5 heads( pretty racy 9 sec setup) wheezed at 7300/7400 rpm last 100-120 or so feet getting to the stripe.
Those heads on that many inches should probably be put in front of a combine or a planter.....lol

Don,

Definately what you said is part of the final equation, what I miss most is the high revving sound my old W2 340 used to make at 7800-8000.... and as much face distorting torque as the stroker make they just aren't as exciting to wind-out.

To go mega-cubes would sure be fun but I think a a big 4.18-4.20 inch bore 3.79" stroke 6.300 rod would be my favorite way to build a W5, the pragmatic side of me says it doesn't cost any more to throw a big 4.125" inch arm in there instead....even if it costs a bit of that high pitch wail that I love about 340's.

The biggest point is for me just to get another interesting motor project going.

Whose 6.3 rods are you looking at? A set would help me piece together a engine on the cheap with the MP 3.454in. crank I got a while back. Someone else around here runs them but all I see are 6.2 or less.

Lots of companies make a (sbc) 6.300 rod with a 2.100 journal and probably a 2" as well. Don't know of any 6.300 mopar width though so you'd need a regrind I guess

Compstar makes a sweet, resonable
6.30 rod I have used. Nice pieces
Like big bore 3.79 motor.
What is around other than those 1053 cranks these days

There was a complete W5 top end in the classifieds last month here... wasn't too bad of deal, intake, good rockers, complete heads.

We're going back to our old 124mph 11sec iron head 360. Add gas, race, no fuss....no muss. And...no more getting scolded for those well into the 9 passes . It was fun while it lasted.
