has anyone used Roger Thelin's mounts? It looks like he uses the dogbone strut as the upper engine mount... anyone haave any experience using this? wftb, I thought your upper mounts were fabbed to connect to the cradle below, weren't they?

i would just like to know how much they cost

I have a set from him, but it'll be awhile before I can work on the car. Paid $60 for them.
Give him a call, he's real good about getting to you.

Finished up welding the sub frame and time for the first trail fit in a car.



I dropped the V8 from the GT and wheeled the LSJ under it. I have to say the LSJ was way lighter then the iron block V8 by the feel of rolling it around on the dollies. It would be great to wiegh then both at this point. The V8 still has about 30 more lbs. to add with the rest of the intake installed.



Once in, it was appearent the Tsudo headers are not going to work unless I completely remove the trunk wall. Too bad, they look good and are the right size for the motor.



Front clearance is real good so far. But the front sub frame bolts are not in yet and need to go another inch up.



Shock tower clearance is good but does leave a lot of room for a torque strut.




The tranmission butt end also good clearance.



The belt side, also plenty of room. On this particular car I dimpled the car frame a little for more clearance for the V8 lower pully/dampner some time ago.

The OEM cast iron exhuast still could be used.



The subframe is almost in. I need to drop it again and tweek the front ears a tad. I think the doner frame was a little off. The front tongues are about 1/4 squeezed in. I should have checked for square before I started.

I plan on working on it all day so I'll post more picts tonight.

Looks good. Just one question/concern. How hard is it going to be to change the oil on that, isn't the filter under the supercharger?

You must have the motor back farther, I got the tsudo header in there with about 3-4 inches between it and the trunk wall... but I dont have a supercharger either
Edaw 0 SEP 22, 03:56 PM
Nice work and that header looks reall nice. Any chance of you going with a smaller trunk?

The factory oil filter is located under the &^%*#(!) super charger and it takes a (#^(!#$)$ extension just to get the cap off then you got to pull the &*%^$ filter up out of the holder. But it will not fit between the (^#!($ engine and super charger so you have to move it lateraly forward to get it out. Did I mention these are (^*$!)($!))&$!( CARTRIGE ELEMENTS!

I plane on a remote spin on filter as soon as I can.

I notice that the motor is at the stock tilt of 15 degrees toward the rear, if you tilt the motor /trans straight up so that you can use the Tsudo headers, will the supercharger hit the firewall?
