questions about ifs for 57 chevy 3200
 
hello all im new to the hotrodders seen. i happened onto a project that im really trying to learn about. my boss had an original 57 that he was going to customize and decided he was getting to old for the project so he sold it to me for 800 dollars along with all parts. which include an early 70s nova sub-frame that i really want to graft onto 57 frame if any one has any info/pics it would be greatly appreciated. thanks

Well can I just put a witness mark on the on the frame of the 57 to determine the length of frame I need to add?

The Nova/Camaro subframes are popular front clip options because they graft onto the stock frame pretty clean. In my research though, I wanted mine to be lower in the front and be able to turn without rubbing, using standard offset wheels that are commonly available. I used the 1978-1988 G-Body front clip which is narrower, but a little more complicated to graft on to the existing frame. I am using 17 x 8" torq thrust wheels and have full steering radius, with the truck lowered 6" from stock. The G-Body also shares spindles from the S10, so availability of 2" drop spindles is good. It will also take the '82-'92 large front sway bar from the Camaro/TransAM as a bolt in. Good luck in your project, and I'm sure you will have a great time figuring all of this stuff out. That's what makes this hobby great, with all of the help from here and at the car shows.

An Early 70s Nova sub is ideal for that truck. It should be rear steer. I just did one a few months ago. Here is a tutorial on doing one. http://enjenjo.com/frameclip.html

I would seriously consider fixing up and using the original suspension over grafting on a sub-frame. It makes for a much better vehicle overall.

Thanks all for the insight my sub is a rear steer can any one elaborate on the too far to the back look? Does that happen with all sub frames?

Byron,
If you plan on doing this I would suggest getting very educated on the subject of that swap. First of all the geometry on the first gen F body subframe / 2nd Gen Nova leaves alot to be desired out of the box... then if the clip is stubbed in off it gets worse. Common on that crossmember is also installing it to high in an attempt to lower it too much. Then by trying to get the truck up to a drivable height, the geometry is so far out that nothing can be done to correct it. Unfortunately here with what we do we talk to alot of guys that try to use an air suspension to band aid the problem because it is a done truck.
Im not saying this is the worse idea on the planet. I have seen a number of them done correctly and now with the pro touring movement as strong as it is, there are tons of bolt on aftermarket parts to correct the poor geometry issues that subframe is plagued with.
I would suggest at first looking at it from a price conscience standpoint. You will need to look at your crossmember and determine what will need to be rebuilt in order to make it spec right... brakes, bushings, tie rod ends ect.. ect... Then look at what it will take to correct the geometry and / or stub it in there correctly and hope that clip has never been hit, bent, or excesive crossmemeber sag that would need to be corrected. I would then weigh that against just simply finding you a weld in crossmember that has been engineered for your application and will be fabricated to run it at the height you want. That route, out of the box you would be getting better geometry, brakes and steering with a much simpler install with predictable results.

very insightful and thanks very much now a couple questions how do you determine what sub you have (1st or 2nd gen)? i picked it up when i got the truck and previous owner could not remember the year it came off. i measured it out and all appears to be true as far as i could tell also do you no of any place i would be able to get some reseach material?

Measure 27 times, with the front sheetmetal in position to ensure you center the front wheels in the wheel well openings. Then and only then should you fire up the torch/sawzall. Tack on the front clip, and re-check everything. Then and only then should you fire up the welder. Measure 27 times, cut and weld once. :)

1st gen is a rear steer.... 2nd gen is a front steer.

byron peters 07-15-2011 03:09 PM

thanks i have fisrt gen then

byron peters 08-02-2011 02:12 PM

ok so i got the sub frame measured leveled and welded the question i have now is about boxing it in what is safe to do around the powering steering mount? box it all the way around except that?

enjenjo you tutorial was very helpful. i noticed you did a rear steer as well. how did you box around the steering mount?

enjenjo 08-04-2011 12:31 AM

I boxed up to the steering box mount, and left the mount itself as it was. I can get a picture for you if that would help.

yes that would help im at the point of boxing but i want it to look decent and most importantly be safe all has been fairly simple , but yet time consuming but thats what its about right
