3500 crank

[34blazer]

i cant remember, but has anyone confimed if the steel 3500 crank is forged or not?

[montess408]

does any body know if this stroker crank would fit in a gen 2 block and what displacement i would end up with after a .030 overbore ?? and would i need to get diffrent rods or would the onefrom my 3.1 be good ? and what about pistons i was gonna get a set from a camaro can i still get them ?

SO, basically, from what i've gathered is:
1. a 3500 is essentially a punched out 3400, with better flowing top end?
2. The best way to gain cubes is with a 3500 crank in a 3400, (since the 3500 is like a punched out 3400 from the factory?)

No, the crank has the same throw, but the rod journals were increased from 1.999" to 2.499". People have been discussing offset grinding them to use the smaller journal rods and making a .25" stroker.

No confirmation yet, but it appears to be billet at the least...

I test fit the crank in a RWD 3.4 and it rotates freely. I did not press a piston off a 3500 rod to be 100% sure, but bolted the rod on with the piston sticking out of the block on the oil pan side, and it looks like it would almost make it - of course I could not get a full rotation this way, but gave an idea...

and the 100cc difference is the bore then if the stroke is the same?

thanks

oh, and has there been any details on specific model/year that said billet/steel and or forged/steel crank comes in, or is more likely to appear in? last i knew there was no definitive answer.

thanks

sounds good

[blkalero]

the forged crank has a very fat casting line

My 3.4 crank sounded like that too.

dave can you tell by looking around the throws if its cast or not? if you can can you post some pics?

the crank is just sitting in the block, if you need any pics of different spots just let me know.

You usualy have to hold the crank by the snout isolated with a towel and hit the end of the crank. BUt it seems to be steel. I would be happy just beeing steel.

The tone is a little different, but as I have said before they both ring about the same amount of time.

Seeing that they have different size reluctor rings and rod journals, they could easily have different tones just from the mass of each.
