Five Stage of grief over the GMC powerplant

[dave silva]

Denial- there has to be something better than the stock engine and transmission.

Anger- you old guys are stupid, I WILL DO AN LS SWAP

Bargaining- maybe if i gave up a lot of interior space i could add a transfer case and a Dana 60 front axle mated to a 454.

Depression - this sucks, i hate having an old engine and no overdrive

Acceptance- ultimately, the 455 and TH425 is really the best solution for this great coach. I can always add EFI.

Dave,

Since you obviously need a viable alternative to the 455, consider the
Cadillac 500. Could hardly be an easier swap: Drill new holes for
the front engine mount (or copy mine), bolt to your TH425, and cobble up an
exhaust system. Maybe add EFI. Voila! Ready to run with us big boys!

No i certainly don't need anything, I have Birch with a 455 and i can do math.

But haven't we been seeing this conversation for years? I posted this on facebook after someone offered yet another non-workable alternative to the
TH425.

Did that teach you to steer clear of Facebook?

I would also say the 472 Cadillac, the predecessor to the later emissions-choked 500, would be an excellent swap. Rock solid, and 375HP with 525ft-lbs of torque. A monster, and inexpensive. Commonly found complete with the TH425 in 68/69 Eldorados.

If we really want to see these things preserved somebody is going to have to deal with social media. It's OK, i don't mind.

Was reading something about an east coaster who wasn't an RV er, and from
the sounds of it, will probably never be one.
He rented a Sprinter Van for the weekend for $1700.00 and took off
unprepared. Ran out of potable water, overflowed the holding tank. Ran the
batteries flat, froze his butt off. He didn't have a good time, to say the
least. Don't know the guy, but am familiar with his type. He went through
all 5 stages and wound up dissatisfied and disappointed. Self induced.
Glad it was a Sprinter, and not a GMC. He laid all the blame on the RV.
Guess he never looked in the mirror for who to blame.

I was actually wondering why the 4T80-E isn't suitable? Can't handle the weight and torque?

As for the thread:

500 cad/EFI/HEI/electric fans if you can afford it: Turbocharge it.

No grief here, just power in spades.

Sammy,
When I turboed my 500 back in 1992, I had a pro assist me.
Since then I have learned from the first and without experience, doing a
turbo is not basic.
I have a ECM that is fully programable as that is what it takes to control
the timing and enrichment.

not careful as it is. My John Beaver build 455 with the 3.7 gears barks the tires off a light if I'm not careful as it is. Any more is like the Ford
guy said of the first SHO Taurus - there's another hundred horsepower in the engine but we can't couple it to the ground.
