i bought a 505 stroker from Hughes Engines, 4.25 stroke, and started final assembly today. the problem is i cannot put two rods on the same crank journal because they dont fit, they are chevy journals and measure like this- crank journal, 2.01, rods are 1.018 each. stock chevy rods measure .995 with the crank journal measuring 2.0. anyone ever run into this problem? i am going to call Hughes Engines Monday just wondering if anyone has ever had this problem. Thanks guys.

Do they fit between the fillet but not down completely on the journal? If so look at the bearings & rods closely, one side is chamfered for clearance...

If they cant even fit in the throw area(a pair of
rods) you can have the rods surface ground(I did
that 1 time on my small block) I had to take .013
off of the inside wall of each rod... or have the
crank cut wider(I JUST had this done on my 4" crank...
it was cut for chevy dia but he screwed up and didnt
cut the width... he did after I brought it back

if i do the rods i guess they have to be rebalanced? if i do the crank it would have to be nitrated and balanced again right? either way im not very happy with the parts that were supposed to be bolted in without any problems, hopefully it will all be worth it if i ever finish it. Thanks Mr. P body

Call up Hughes and tell them to replace the crank...

You have Mopar width rods for a Chevy journal. Are these K1 rods or Eagles perhaps? There is a Chevy width rod, and a Mopar width rod, that both could be used on a Chevy journal, but the crank has to have the appropriate width.

i spoke with Craig yesterday at hughes, he told me to box the rods up and they would send a return slip and have them picked up and correct the problem by cutting the sides. i asked about the balance and he told me it would not make a big difference. however this doesnt make sense to me. what do you guys think?

To me thats the wrong way to do it... if you go with
another set of chevy rods you would need to have those
cut down... I would have the crank widened... and yes
the balance would be off... I dont know how much

I doubt he wants to go down that road, He will basically be made out as the moron, and made to feel like a school boy playing with a 5 hp briggs.
Probbly just have to have the rods narrowed, and rebalance things.

so say something happens and i need rods down the road, the crank journal is too wide for a standard width chevy rod, and not wide enough for a mopar width rod with chevy journal. so this is a total disaster. so really Mr. P body is correct or i need a new crank.

we always cut rods to get a final rod-rod clearance dimension,,
no,, absolutely no,,, no,, no,, you will not have to rebalance it,, cutting .020 off a big end will take about 1-2 grams off,, which will change the bobweight 2-4 grams..
do you rebalance your motor when you run 5-20 oil as compared to 20-50 oil,,, thats prob bout the same difference

no, but i dont pay 350 dollars to change my oil weight either. i asked because i didnt know.
off topic: does a quart of 20-50 weigh the same as 5-20?

He is trying to help you. The oil weighs the same but because of the thicker viscosity there will be a larger volume of oil on the part.
