258 connecting rods

dwg86

I'm looking for a set of 258 connecting rods for an amc 258, casting number 707 or 352.

I have a 79 cj here with a 258 but have no idea what the casting numbers would be. I am not to keen on teking it apart but if it is worth the trouble I will. I guess I am saying how much you willing to pay for the rods and any idea if these might be what you want?

I am near Atlanta Ga. I just won a set on ebay, but I can use another set. The local pullapart wants $13.00 a rod. I won the set on ebay for $15.00 plus shipping. I am building a couple of 4.0 stroker engines (4.6L). I got 2 crankshafts from pullapart for $31.00 each. The 4.6 stroker is a 4.0L .030 over with a 258 crank and rods in it. With a small cam people are getting as much as 269hp @ 4800rpm and 340lbft @ 2500rpm, without really effecting gas milage. (If you can keep your foot out of it)

I'm not sure. I haven't received the rods from ebay yet. It should be cast in there somewhere.

For $46 it is not worth the trouble to me to take apart a motor. I will just leave it in the jeep and scrap the whole thing out.

jerry

the # on the rod I have is 237. Jerry

getting ready to scrap the J10 with the 258 in it, if you think an 80 would have the correct ones let me know what you could give for them, would need to dissasemble motor, possably pull it out first.

Getting ready to list a set on Ebay if you haven't found these yet. Has the number 707 on one side of the rods and 237 on the other. From 1979 CJ7 AMC 258 105,000 miles. Standard pistons are still attached. $20.00 plus cheapest shipping I can find to another Jeep guy that isn't going to resell them. Can have pistons removed at Machine Shop, possible there won't be any charge. Thinking about this a minute - is there a difference in 258 and 232 rod lenghts - hate to send the wrong ones if this engine had been swapped.
