Alans Scratch build

[Bryan Koehler]

What modifications where made in order to run that G9600 box inverted?

Hi there, Seems weird that the trans is upside down. However that is how it will fit. I think the only mod is to seal the vent and drill a hole in the drain plug.

What would be even weirder would be if it were not mounted upside down... you would have 6 speeds in reverse!

I have a 351 roller and was planing on stroking to 408cid. I was told the 408 would be more reliable than stroking up to 427. I think you have to bore all the way out to get up to 427. Whats your thoughts on that? I think 408 was going to be a .030 bore job vs .090 on the 427.... its been a while since i lokked at the exact specs.

 

[Brian]

Depends on the stroke. The 427 is most often a 4" throw with a 4.125" (aftermarket) block. I don't think you can bore a stock block .125" over.

I think the 408 is a stock block .030 over with a 4" stroke.

That's a glorious mess of plumbing. Active power? Corvette rear suspension.

Yes it is Active power

What motor mounts are you using?
thanks

Scoff if you want, but on kit cars and such, I use a Mustang 2 front end strut bushing. It's on the far right of included pic of my Cobra.

Here's the big plus. With a lock nut, you can adjust the firmness by how hard you smush it. I welded the bottom cupped washer to a piece of square tube, and the motor mount has a thickened plate with a hole. It was a far better solution than the Mopar motor mounts Lone Star speced.

Couldn't find a better pic.

I am not to the motor yet

Bidenomics has made building the GT painful. However moving forward I am adapting the 996 trans to the 351 roller block, I have to machine the adapter plate. Then build the engine mounts and adapt the 996 CV Joints to the C5 output shafts.​

For now the 427 Stroker is out and the 351 is in​

Good to see you back. I was enjoying following this build.

Its great to be back !!

Machined the 351 W flywheel to fit the 996 transmission, Next its the adapter plate, since aluminum is so expensive it will cut from 1.5 thick plywood and if it all fits then get aluminum.

Starting the welding jig squared up ends on the Hass using XYZ to make measurement. View attachment 106163

Building the adapter out of wood on Hass mill the drawing on internet was good and no Drawing on the 996 trans. So I used 2 locating pins on the Hass and used X Y zero to locate 996 pilot shaft with wood build up. Measured 1.400 from edge of bellhousing and bored for slip fit. To follow with clamps and hand drilling with guide bushings a .200 hole that will plotted in X Z and to create points for CNC program. Wood is the best way to get this done fast. When I get it right then I will cut the aluminum adapter

I also like making a practice run in things like this. Sometimes I use poly pro and other times I use wood. I just have to be careful that nothing gets in the residual coolant that always seems to be hiding .
Great work as always ..

Regards Brian

Great to hear from you Brian, back to work on the GT. Every thing cost more than I'd did when I started. Any way moving forward once trans is attached I need to cut machine axles and tack weld engines mounts. Using wood allows for lots of mistakes corrections. Again thanks for all you help on the GT
