'66 nova project

[kevin_l]

So, I haven't been messing with the nova too much lately, I am still waiting on the transmission crossmember. But I have been attempting to find a header solution and an answer for the a/c compressor.
I've been measuring around on the motor and trans trying to see if I can shift the motor to better clear the headers. Here's where my lack of car building experience is costing me. I Now have my motor mostly level with the subframe, but noticed the trans (tail shaft is just sitting on a jack stand) is shifted to the passenger side approximately 3/4" I read that some manufactures build this offset into the motor mounts to eliminate drive shaft issues, Also I read that DSE's mounts their engines centered. But my motor and trans are wanting to rest offset. If anyone has some insight on the matter I'd greatly appreciate it, If not I will call DSE tomorrow and see what I can find out from them.

Until I find out if the crossmember is being built with an offset and where the motor's final resting spot will be I can't move forward with the transmission tunnel modifications, header solution and finding a compressor and mount to clear the subframe.

Hi Kevin,

Just went through your build thread and NICE job! For what its worth the Nova's (62-67) came stock with a approx. 1/2" crankshaft offset to the passenger side. I have one of the earlier DSE front clips for my 65 Nova and the engine still sits approx. 1/2" to the passenger side. Hope this helps.

Thank You, I didn't get a chance to call DSE today to ask. The 1/2" offset would explain my header issues. I guess I need to double check with the guy building my trans cross-member to see if he is factoring offset in or not.

No, should just be offset by 1/2". The block for the most part is parallel with frame rails.
Just as a check starting with the engine. Find your cam OR crank centerline and use a square or something to plumb a line down low enough so that you can measure over to your frame on both sides. You should find a number like 13-5/8" to the drivers side frame & 12-5/8" to the passenger. This is your "1/2" offset to the passenger side.

Also, since you have your rear-end bolted in. Transfer a chalk line down the center of your car on the concrete floor beneath (plumb line down "center" of your front sub-frame and mark on the slab, then plumb line down center of your rear frame rails and mark on slab,,, connect/snap line connecting the two) This will give you a decent reference "centerline". You should find if plumbed up to your crank/cam centerline that it is 1/2" off to passenger side. You also should find your pinion center the same...

Kevin, also remember (if I remember correctly) that your engine/transmission should be approx. 2-3 degrees "down". I think mine is closer to 3 degrees down based on DSE recommendation...

Ok great! Thank you for the explanation. It's tough to really determine how the motor is sitting but your idea with the center line and chalk line makes a lot on sense. I'll give that a try this week and see what I come up with. One other issue may be is the rear end isn't located yet. I just threw it in there for mock up purposes.

You are correct about the offset, I did a quick measure with the tape from the head to the upper control arm mount and I am 1/2" offset to the passenger side. I'll measure the tailshaft to the rockers and see if I have that same 1/2". Thanks again for helping out, I am a newbie when it comes to this type of thing, just goes to show how valuable members on here are. Thanks again.

Had tires mounted and balanced today, Just couldn't resist test fitting them and rolling the car out for a few pictures.

Tires are Michelin PS2 315/30r18 and 275/35r18

The more I see this car the more I am in love with it.

Thanks, I was grinning ear to ear once I let the jack down. Can't wait to get this car driving!
