what was the reason not to use the subframe out of a 78 nove on a 1st gen camaro? uuuuummmm.....i was able to get ahold of one and it bolts up directly to my 1st gen. the only main problem was the front two mounts on the subframe are a little low and i had to add a spacer. besides that everything else aliens up correctly. :hurray:

It's a great conversion if it is as easy as you say?

Just make darn sure the front axle spuds are centered properly and that the rad. support and tranny cross member align up OK and you should be good to go.

PS., and fwiw, I would do this conversion before spending a basket full of money on a custom S/F!! But, then again, I'm a tight-as--, er, eh, "frugal" is all...

ANd I have mentioned this conversion several times here in the past!!

I have heard it mentioned and also mentioned it myself. I have never known anyone to try it so I don't know if it works. Report back stang on all the details and if it truly "bolted in" I think there might be problems with core support mounting? wich leads to body alingment problems?? I don't know any of this for sure? I sure would like to know if it's a true bolt in with a few core support spacers and will the fender wells bolt in and wheels and tires have no rubbing problems. Will be very cool if it does. Cheap big brakes, front steer..........awsome.

i already see the front rad. support will not bolt up. for one reason i cut off the front horns of the subframe. i'm not running a front bumper so i dont have to worry about mounting brackets for that. here's a picture of what i cut off and how the steering lines up

yea i believe i may have to trim a little off the bottoms of the inner fender wells. i believe this subframe arches up higher. if so its not much at all.

my plans are to fix this 67 camaro up completely modern and sell my 93 :)

the front horns will not stay like that. i plan on making them striaght like the 1st gen subframe and boxing it all in. then cut a hole in the top for the rad. support.

one thing i do know. the disk brakes are in working order. this came off a running driving car. lol its 4 inches tall now. :beers:

It was mentioned that the Nova subframe is front steer (it shows in the picture). Whereas your 1rst gen is/was a rear steer. Are you sure that the pot coupling on the steering intermediate shaft will reach the end of the steering column coming out of the dash?

If you have the Nova frame located correctly in the picture, it sure looks like you will have to raise the end of the intermediate shaft up and outboard in order to reach the end of the column. It also looks as if you will have hard interference with the upper control arm when you try to do that.

I smell some problems arising with your steering. Upsetting steering geometry always spells trouble. But, keep us all informed. It sounds like a great idea with a bit of work. Good luck! :beers:

Does your Camaro have a tilt column? The reason I ask is that the standard (non-adjustable) column has a stamped flange on the end in the engine compartment. It is a stamping and is press fit and staked to the steering shaft. It is very secure. Even if you remove it, I don't think that the pot coupling on the intermediate steering shaft will bolt onto it.

A tilt column will have a detachable flange that has a pinch bolt that holds it in place on the steering shaft. Removing the tilt column flange, you will find that the I-shaft pot coupling will bolt right in its place.

the column that is in the car right now is a column shift. i am converting that over to floor shift column. i wish i had a tilt but....i work with what i got for now. i will post pics whenever i get the column switched over and hooked up. this will be soon so i can move to car around the yard.

This post is getting intresting to say the least. I wish your sub frame was not cut up, but that aside please document what you do with pictures and words. This subject has been talked about many times but never done or at least posted that it's being done. Keep us informed.

On a side bar I talked witha Race Car fabrication guy that told me for $1000.00 he would put a second gen sub frame under my 67. I provide the subframe and suspension. All in all the advanatages vs the cost seem to be that it's good deal for aguy like me that could not fab his way out of a paper sack (fab meaning using a welder). I have not even come close to taking him up on his offer but someday when the money is right and I really want that extra something for suspension and brakes who knows..................ya right like I will ever have any extra money for something like that!! I would be better off taking a welding class!! LOL !!

David,

I never did get a verification if the width differences between the 1st and 2nd Gen. cars was just the hub wheel mount diferences, drum hubs vs disc rotor hubs??

And I have talked about this conversion a lot in the past.

Please keep the info and pic's if possible coming!!

i layed a extra fender on my car just to see how far it stuck out and it looks normal. sticks out just as far as the rear. i will get some measurements soon.

i came across my first problem today guys and i need your opinion on what to do. here is the link for a better understandingmy oil pan rubs the cross member

is it my frame mounts? or the oil pan?

You need to use the motor mounts from the original sub frame and I think you will be ok. Others my chime in here on this, but I am pretty sure there is place to bolt up the 1st gen towers (mounts) on the new sub frame. I believe with the older towers it sets the engine farther back to the firewall. That also looks like a big block. Your going to need a pan with only one step in it for an F body install. The ones with two will hit the cross member even when everything is right.

so just change the oil pan. cool. yea thats the 366 BBC truck engine i've gotten. right now i'm mocking everything up and checking for clearance issuses. i will then take everything back appart and clean/paint/polish my parts up.

No not just an oil pan change. Read the rest of the post. I am pretty sure you need to change or use the frame mounts from the 1st gen frame. After doing this you will also be needing to change the oil pan. Once again not positive and just going from a faded memeory. THese are places to look though.

I think that the First Gen. S/F frame mounts bolt up more towards the rear lip of the crossmember they bolt to.

Check it out and you will see what I mean.

I have posted before just how I would do this if I had a Second Gen. S/F and needed metal-working tools and a big garage.

I would set both of them side-by-side and match their axle spuds right together and start from there!!

This way, you will know everything fits!!

As for the pan, you might have 7 qt or bigger h-d BB truck pan on the mock up motor that won't fit regardless! I know, my '75, 454 P/U motors pan is the same as a cars pan so it was fine.

BUT I will say that my 409 "W" motor's truck oil pan fit my car fine!!! Sucker held at LEAST 7 qts!!
