I need pics of a 60* rod

[ForcedFirebird]

Ah yes, what was I thinking? The reason ofr the odd fire in the 1st place is the 120* crank throws and 90* bank angle.

John,

What about having the 3500 crank ground to the 327 5.7" rods, or were you looking to keep the larger rod pins? I haven't heard of anybody managing to break a rod pin with the iron cranks, now that you have a forging, I don't see you having problems.

I may look into SBC "big pin" con-rods and a reground crank. That seems to be my only viable option. (I believe that thats a 2.150 or a 2.200 crank-bore)

Sounds good. You can get them on the cheap, Eagle H-beams go for less than $400/set of 8. You will probably just have to shave the big ends equally (both sides) for width.

Here's an ebay site with them less than the Eagles and seem to have a lot of options for length and pin sizes...

ebay rods?

[Driver_10]

Does anyone know the exact diameter of the 3500 crank-pin?

2.249"

Then the crank would need to be ground down by .0290 or so to accomodate "large-journel" SBC rods.

Seems like a lot of meat to skin off of that crank

I guess Ill go and buy a new set of rods as soon as I get off this post.

I don't feel that it's too much since you can get most bearings up to .030" oversized.

"large" SBC is 2.1, so that would only need rougly .150" smaller rod pins, "small" SBC is 2.0 ..

in the world of 4.3's (which have the same rod pin diameter as 3500's), turning the rods down to large SBC is a very common thing, for using off the shelf 350 rods.
