looks solid!
I say 86-7 GN or T-type drivetrain. A turbo LS would be cool of course.

Re: GNX2 Has Arrived(Feb. 23, 2011)
Is there a budget on this at all? Also what about time-frame estimate? Always good to have.
If it has a 400, as megaladon6 suggested in this thread: viewtopic.php?f=3&t=26161&start=15#p202091, why not keep the 400, destroke and turbo it? Imagine a destroked 400 roller cammed, aluminum headed and turbo'd. That would be insane torque and horsepower, and totally streetable. You would still have big cam idle and gobs of torque. IMO such would be the epitome of a GNX2. GM might even offer to buy it off you when it's done.
P.S. If you want more gear, I believe TCI makes a 6L80E 6-speed manual/auto valve body transmission. I'd like to see one of those in a g-body.

Thanks. A turbo big block would be even cooler 🙂

What engine, hmnn what are your goals for the car? What do you really want to end up with & or how are you going to use the car? 400 sbc already in it for ease & bang for the buck it would be hard to replace. Did the Caddy swap as you can see in my photos and miss it dearly. LS series would be a strong consideration looking forward and at fuel costs. Again what is your goals or important to you? Limited mileage, nostalgia, crazy big block torque Caddy. Mileage, modern, latest car trend, LS.
Transmission? Drag car usually a three speed th350 or th400 depending on engine choice and output. Almost anything else in a gbody the best choice all things considered is usually the 200-4R. http://www.extremeautomatics.com
Edit Yea a GN drivetrain if you can find one reasonable can also be a great choice.
Edit II You are suggesting destroking and turboing an already flimsy 400 small block that you don't even know if its the original bore? Racers do 383s instead of 400s for the fact that the block & crank don't twist and wiggle around leading to self destruction. 400s are easier to make power with but harder to keep together when you do. The 6l80E is interesting but I would not buy a transmission from TCI. They are recognized by joe beginner because of their long standing advertising budget.

My only goal is to murder it out and make it more convient(a/c, heat). This is more for my girl than it is for me(the convience stuff). But it is true what they say. Once you get used to some power you don't want to downgrade. We had this discussion before when you helped me out with info on the caddy motor. I eventually went with a big block buick and loved it. Gas mileage isnt a issue since I wont be driving this one everyday right now. Heck I drove that big block everyday as my daily driver until I sold it.

Power brakes & AC usually start to get iffy via lack of vacuum shortly after cams exceed 230@50 duration. Sometimes an external vacuum canister can help but I have not messed with one.

Got a lead on a caddy 500 engine for $175!! Probably going to pick it up next week. I was interested in this motor about a year and half ago and a salvage yard said they had one. I went and check it out but came across a better deal on a rebuilt buick big block. I called yesterday by chance to see if they still had it and they said they did. So GNX2 will be Caddy 500 powered. Possibly built to stroker.......

Re: GNX2 Has Arrived(Feb. 23, 2011)
Surprised you sold your Buick it was cool and I'll bet fast and not yet even finished. 30 years of hot rodding the Buick 455 & Caddy 472/500 are my two favorite street car engines for the gbody. I sold my spare "still ran when pulled" 500 the other summer for $250. I had never run it just knew that I could turn in over by hand. The guy who bought it blocked it up in the back of his pick up had fuel & a battery and started it. I thought it would be rough after moving it around and not running for 4 years, nope after a little warm up it was smooth & had clean exhaust. I knew I shouldn't sell it then but such is life sometimes. He gave me asking price with no bartering after seeing it then we loaded it up.
Honestly going the stroker route is at least an extra $1,000 just in parts and is overkill in a gbody. The 4.3 stroke of a 500 makes LOTS of torque down in the low 2,000 rpm range right where you drive it. Even with a good bit of cam.
Plus the heads (as do all old v8s) already need work to allow her to breath deep and work toward her potential.
If I built a stroker it would be to a smaller BBMopar bearing size for the primary purpose of having an engine that likes and can take more rpm better. The smaller bearing can still easily take the load but does not make near the heat. Safe bore to match the stroke would end up with a 542ci and a need for worked aluminum heads in order to allow her to breath.
What year 500 and did it come from an Eldorado?

Re: GNX2 Has Arrived(Feb. 23, 2011)
Not sure yet. I probably wont pick it up until Wednesday. Yea you are right about the stroker. I still keep in contact with the guy that bought the car and he said he has had some fast cars but the regal tops them. He is currently in the process of putting a beefed up rear end. I told him that he's gonna end up around a tree somewhere. 3.73 behind a big block street car....hmmmm. 430's are 360 hp and 475 torque factory. Motor had beefed up 455 heads, cam(2000-6000rpm), intake, and was bored 40 over. I can only imagine what life will be like with the caddy motor. I will probably break it down, clean it up, and do a basic rebuild with mts #10 or #15 cam, intake, etc.... I might possibly go with the same type cam I had in the regal.
It wont be going over 5500 rpm but I know about the valve train needing to be upgraded regardless. Do you remember the numbers on your motor or estimates based off what you had done to it. What about comparing it to other motor specs and built motors. I know the caddy stock specs are impressive.
