Good Day Folks,
New to us is a 87 HR Presidential on a Chevrolet P30 454 CI Seems It is very clean, has a little over 30K on the clock. I still need to pick it up. the Gentleman I purchased it from will hold it for me until the springtimes.
I like this one because it is Vintage and is in great shape.
I do have to look over some of the drive train and I want to install disc brakes
Balance the drive shaft, possible rebuild the rear end and add a posi unit.
It has a 3speed trans in it now. I'm thinking of seeing if I can install a 4speed
transmission in it. One of the things I think would troublesome for me is the shift linkage, I would suppose I would have to shorten the drive shaft.
I did see in one of the posts a question about an over and under drive.
Not sure what that means, and how it works.
Will it install behind the 454? Anyone have any answers about this. I was also on ebay and seen a 502 tow truck engine forged internals, roller lifters and rocker arms. Make will over 500 lbs/ft of torque and around 450 HP.
Should be and easy swap. I would also like to run electric fans. Less parasitic drag on the engine. I also want to install Doug Thorley Headers with Dyaflow dual exhaust. These need to be coated.
Another thing I want to do is install Load Leavers, and new tires. Does anyone know the tire size? Brand and Ply rating.
Any thoughts and suggestions will be very welcome. I have lots of experience
building Hot Rods, but no experience with Class A Motorhomes.
The Vehicle seemed to been setting around for a few years. He told me his
Grandparents own it for sometime. They seemed to enjoy it.
Thanks for taking the time to read this long winded post. I do need some
