Eagle crank and rods are clearly marked. The block has an idenfication plate on the back as well that should clearly indicate whether it is a 4G63 or 64.

Can't help you on whether or not you're getting a stroker or not.

I assume you've already got a 6 bolt head?

get me a pic of the timing belt side, I can't promise I will be able to tell, but it will give me a better idea.

IIRC I think the 2.4 had individual main caps. This may be the 6 bolt I am thinking of......

Yes i have a nice 6bolt head already. I really just need to know if it will work on this shortblock or not .

does the owner have receipts of the parts that were used to assemble the block?

No he does not.

The part number on the crank you need to see is right beside the eagle logo... You can look the crank up and see if it's a 100mm crank or not.

You can use the crank in either a 4g63 or 4g64. The stroke is the same either way.

And yes, you can use a 6-bolt head. I'm sure you know exactly what you need to make everything work.

So from the pics would you say this is a 4g63 block or 4g64 ?

It is a 4g63 7 bolt block. I forget which years came with the cradle.

Im sure all 7 bolt 4g63/64s came with girdles. If it is a 4g64 it should be stamped on the side of the block close to the water pump outlet. That said i agree with nuclearr, thats a 4g63 block. 4g64s have more oil drain holes drilled into the block

Heres a pic from my build awhile ago. this is from a 7 bolt 4g64 out of a 1999 eclipse spyder gs. Its stamped by the oil filter housing/water pump outlet.

How does someone build a motor like that without having one part or machine invoice??
