[455Grandville]

Around 2000 I bought a rust free 455 Granville just im case I needed extra parts for my other one. Drove it to my cousins old storage building and never touched it.
Fast forward to today; my son has been watching Roadkill and expressed interest in finding in reviving an old car. I told him we have one sitting out at cousin Tims. He was excited, so we drove out to look at it today. Luckily he took a liking to it as CL is full of overpriced junk sitting in fields that I’d rather not waste money on now.
We then bought a battery, changed the oil and got it running with gas off a can. Couldn’t believe how well it ran, either.
Tomorrow we’re going to tow it home and drop the tank, work on the brakes and see if we can’t put it on the road.
Not an exciting car but, I’m happy I’ll get some quality father/son time in plus he’s looking at performance parts asking about rebuilding the engine (I can machine the engine at my cousins shop)

A 455 Grand Ville sounds plenty exciting to me. Should be a fun car for him.

[Wick]

Awesome! Teach him to drive a stick too. Unbelievable to me how many kids cannot row the gears.

[Ben M.]

That's awesome. My kid wanted a Cadillac so she has that... but if I could convince her to drive the '71 Bonneville...

Plenty of quality father/son time to be had. Amazing you had the forethought to pick up one of those when they were still to be had for pennies! The craigslist junk is amazingly overpriced these days.

I wonder if any of them sell, though.
I just can’t see anyone giving $2,500 for a rusty ‘77 Caprice sedan that’s been sitting in a field for years and there’s many ads like that on there.

He’s got a Kawasaki 140 so, he’s almost there.

[Ben M.]

I doubt any of them actually sell at those prices, but if the seller is making a cash grab or clueless I don’t want to bother wasting my time even contacting them.

Convertible?

[hurryinhoosier62]

Good deal, Brad. Looks like a perfect father-son project. Geez, I cannot believe he’s fourteen already.

That’s great- I will never forget my dad and I dragging home my 65 Grand Prix. The motor was toast so we dragged home- you guessed it, a 74 Grandville that I bought for $25. I gave that Grand Prix back to my dad for his 57th birthday, but I kept the memories.

The 75 Grandville is my favorite big Pontiac! I still remember passing up a running 75 455 about 10 years ago for $700. Damn.

That's a wicked cool car for him to work on! Drop on some 6X heads and throw a decent camshaft in it and you'll have a powerful land yacht.

[shaker455]

Very Cool!
Is that car a convert?

[Firedup6975]

Awesome! How old is he? Anytime you can get our youth to have interest in classics it puts a smile on your face and theirs. keep us posted as he works on it.

4dr hardtop. But it should be safe.

That’s the combo I have on my 75 GV ; 6X 400 heads with pocket porting & 3 angle valvejob, Ram air restoration exhaust manifolds, no cat, dual exhaust, 255 DEH competition cam, roller tip rocker arms, 1971 intake manifold (no egr) the difference between the original 7.6 : 1 455 is night & day.
Be a great car for him to pull his off road toys to the parks we have around here as well.

I always wished that my dad would do something like this, but no way. He wasn't that kind of guy. So I promised myself that if I had the means, then I would do it with my own son. We did that with our "one foot in the grave" Tempest. There's no greater feeling of accomplishment to me than resurrecting a car and getting it on the road.

Daughter is out of college, 21, out on her own and recently bought a new Subaru BRZ.
Her T/A is now mine and I’m upgrading the suspension on it.

Most of the 455's I bought were out of junkyard Grandvilles. Must have been the base engine in most of 'em. Paid $75 each for 'em, from a scrap iron dealer.

He'd let me take 'em to my shop to pull the engine/trans. For the price of just an old scrap body of most any kind, they'd bring the cars to me, then come back & get 'em after I removed what I wanted from 'em.

I'd rebuild the short block with a reground crank kit & TRW forged pistons, add an 041 clone cam & Rhoads lifters, then put some 400 big valve heads on 'em, along with a rebuilt Q-jet, then race 'em in area bracket races. Probably made around 400hp/500 torque. Those 455's broke lots of stock parts, won lots of races, & provided lots of fun !

Yeah, that was definitely back in the good ole days !

[Drag Star Le Mans]

seems to me one of the first episodes of Roadkill had the guys thrashing a Granville. So cool deal he has a Granville as his first car.

If it's a 76, it might have 6X-8 heads (?).
One thought even if it is a 76, it could still have that goof ball quadrajet, that is usually mostly on 75's...I'm sure you have a stock of parts
6x-8 heads will get comp ratio in the 9ish:1 range. The 068 cam will give it a little better breathing than the 067 that's likely in it. Nice that it only requires stock springs.
I see no need for more gear or a O.D. Trans. Some easy and cheap engine mods should make it drive-able with land speed record differential gearing.
The intake might be the iron lump with the huge sump in the bottom. Later EGR intakes are lighter and perform well. The large sump unit performs well also, but is just a bigger pain to work with...
Not sure what you can do to the exhaust in your state, being over 40 years old, I hope emissions is not an issue.
It's good for a kid to learn to drive in a big car...safety first of all, second, maneuvering that thing will be good for him. Little cars are way easy to drive...little skill needed.

I have a friend that stuck with his sons first vehicle project. Started at about 8th grade, finished around age 25... It DID get done! I will try to post a picture of it..even though it's a pickup!!!
Having a relationship with ones child is such an awesome thing, very little of that going on these days! My hat is off to you for doing this. Maybe your example can rub off on other parents!!!

I’m going to leave the engine alone as we’re going to build a spare 455 with 6X from my junk pile at my cousins machine shop. We’re going to go through it front to back so it’s long trip reliable.
I’ve told him after he graduates take it cross country to see his family in Texas and California to see his extended family like my wife and I did 20 years ago and see America.
