this is what ive found out so far as i progress to finish the car and upgrade it in the future i will update the info on this list and add too it if you have any question or info feel free too post

after doing more research the series 1 can fit the grand national cam and crank into the block

the way you can use the cam is you need a lg3 timing cover and you have to machine off the oil pump lobe and end gear on the gn cam shaft also you need the cam gear off a lg3 it will fit perfectly.

from what ive looked at the way you use the crank is you have to use the came also its a direct fit into the block you only have to change the cam and timing chain and sprokets which give you a upgrade you can now use the double timing chain for the grand nationals

to sum it with this setup a series 1 3800 can handle 800 hp

one thing i forgot to meantion you have too use a lg3 modded flywheel with the 4t60e all you have too do is elongate the holes for the tourqe converter too fit

Wow, that is quite a list you have going on there. Are you planning on switching over from supercharged to turbo? Are you using the custom grind to change the engine characteristics (less low end, more top end)? How do you plan on keeping the differential together? Do you have any pics of the build?

Yea, what ^ said.

This is just all research that I'm posting up that I mite be doing in the future but I am building the series 1, I have the forged piston and rods and raised the compression to 9.1. I will be keeping the supercharger for now, and do a regrind on the stock cam for more mid too high range power. I would do more this year but I need too sink money in other places

I plan on welding my diff I think I have a build log on here somewhere just need to find it
