First of all....the machinist that is doing my block is a nice guy and always takes a minute to make sure I'm not missing anything...So if you are in the southeast Georgia area....bring your stuff to him in Statesboro.

Okay...first problem. I ordered the stock rebuild kit from Howell and since that kit does not come with rods I ordered the Eagles. The Topline pistons that come with the stock kit are the pressed kind. The eagle rods are the clip kind.

Can I still use these rods with the stock pistons. Do I have them pressed or do I use the clips if I can use them. The machinist said that I will need to get either different pistons or different rods depending on what I wanted to do and that in some cases you can go either way but wanted me to call and make sure. So I thought I would ask you guys first.

Any input is appreciated

dont know, but Id go ahead and replace the pistons anyway. JE's or Wisco's wish the compression needed to fit your future plans. Why not just get all the bottom end done at once so ya dont have to tear back into it?

I really can't afford JE's right now.
;(

Have him rebush the rods for a press fit wristpin.

damnit dino i was going to say that. dinos right, if hes a decent machinist he should have no problem doing this.

Correction, he could have major problem refurbishing the rods for press fit. They have a brass sleeve in them to accept the pin and provide a decent surface to float on. It has been a while since I've done anything with a 420A motor in the shop and when I worked there I was too absorbed into muscle cars too care about a 4-cylinder, but I do remember what floating rods looked like. Best bet would be too buy the aftermarket pistons.

I think I'm gonna go with DarkOne and SILVERNT on this one. Thanks guys.

LOL....More to posts to come as I work my way through this rebuild.

Actually, it's a fairly common practice in the 4g63 world. Many o those guys distrust floating pins in high HP applications, because a sudden burst of heavy knock can destroy that brass bushing, which in turn tears up the wrist pin, which fails, etc, etc, etc...

Perhaps i should have vtcomp offer his input. He's a professional engine machinist, and he could offer more in-depth input as to exactly what the process entails and what you should expect.

I personally like floating pistons, we have never had a pin related falure. The problem with bushing the rods, is that floating rods use bushings, you would have to re bush the rod (around $200)which can be done,the problem is that you can't heat the bushing to press in the pin without damaging it. You will have to decide if you want to pay for good pistons (around 550 with pins and rings. The fact that your pistons don't even have floating pins makes me wonder about the quality. I guess it all depends on how much power you are planning.

It'd be great to have the JE's right now, but I don't think I can handle the cost of that right now. Weak-ass Ruby Tuesday paychecks just don't give you much to work with. Dammit.

This isn't for high horsepower applications, just dependable street applications.
