I was putting my 428 in and things went really good until I tried to find the holes to screw the engine mounts to the body. As I set the motor in I found that I was not able to get the motor far enough in toward the fire wall to get the bolts in to secure the engine to the frame mounts. When restoring the car I did pull the front frame off to sand blast. Is my problem likely that my frame is not positioned correctly? If so what is the best way to move the frame forward? I have already bolted the motor to the transmission housing. I also have the front fenders on the car. Ideas? Am I missing something? The frame has not been aligned on the body yet. Was going to send the car to a frame shop for that.

You're going to have to unbolt the fenders to slide the sub frame forward (at least at the cowl and door jam). There are two alignment holes next to your forward subframe mounts. I used a socket (forgot which size) to put up in the hole to align the subframe. If your steering wheel is connected you'll also have to loosen that. Is it the engine that's hitting the firewall or are you using HEI and the dizzy is hitting?

I would go beyond just aligning the (roughly) 1/2 inch subframe alignment holes. I would get the frame alignment measurements from the shop manuals (Supplement for '67) and test them with a plumb bob and masking tape on the floor underneath the vehicle.

I just installed the subframe using 1/2 inch bolts to align the subframe alignment holes and found later my measurements were still off about 1/2 inch. I was sure that was NOT going to be good enough to prevent issues down the road (panel and front wheel alighnments)

(Never mind - computer posted twice)

Alignment holes, one on each side .610 in dia. I turn 2 pieces on the lathe with a slight taper. Plumbob to the floor and mark set to the manual dim.I had to buy a Camaro assy manual to find all the info but it worked out fine.

does anyone have the supplement for the alignment that is discussed here. I am in process and have a guy that is helping me who is leaving to Alaska in a week (he is a commercial fisherman). Would really like the engine running prior to my main (knowledgeable) help takes off. He is an engine guy so the tuning would go much better with him around.

Sent you email can send pics of manual pages if that would help.

Do you have my e-mail address?

Is this what your looking for?

This video tells it all!

Hi

When I looked at the video it does not show where the guy is measuring from when squaring the frame. It shows the center point under the motor, but not the point on the frame rails. In looking at the diagram you posted I can't see that point in the diagram clearly either. Would love to get that supplement e-mailed. Any help would be appreciated. Buckeyebird said he would e-mail it to me, but I did not get it. Hope he looks at this tread and tries again, My e-mail address was wrong in my profile -- oops ---- Thanks

Thank you vikki

Is the master gauge hole the one that is the pilot hole near the frame mount bolt hole or is it the hole where the bolt goes through the frame and bushing into the body?

The master gauge holes are the "pilot" holes on the cowl mounts.

You now have what I was going to send you update your email address and I can send the shot out of the Camaro manual also if you need them.

My e-mail address is updated. Also sent you a PM with my e-mail address yesterday or the day before. thank you

Does this make sense?

I checked the frame for Square and length point to point and it was dead on. My motor still would not go back far enough to bolt into the motor mounts.

I ended up unbolting the trany mount and then it went right into place and the trans then slide back to a point where the trans mount would not bolt up to the cross member. I had to drill new holes in the trans bushing bracket backing to get it to bolt up. What is wrong with this picture? The bolt holes had to be moved back about a 1/2 inch to make it work. The motor seems to sit about right in the engine compartment. I have a after market th400 cross member for my th400 trans. The trans was in the car previously bolted up to a pontiac 350. Confused!! this happen to anyone else?

Is your trans long or short tailshaft? Have a pic?

Trans is short shaft. It was converted to a short shaft. Was originaly out of a big car and we had the tail replaced with a short shaft setup. Picture would be hard. It is siting on it's wheels. I am squeezing under the car to work on it.

I had to use a really big C - clamp to shove my tranny forward enough to get the tranny mount bolts in. But I doubt that they were off anywhere near your 1/2 inch.
