Trying to figure out what my car will weigh with a small block/th-350 instead of the glide/L6.

A stock L6 weighs 440lbs, and stock small block weights 575.
Whats the weight difference betweeen a dual plane Iron intake, and a dual plane Aluminum intake?
How much lighter is an Aluminum water pump?

Whats the weight difference between a TH-350 and a PG?
How about the difference between a 10 bolt and a 12 bolt?

How much weight will be removed by taking out the A/c compressor, the condensor and the cooler infront of the radiator?

It weighs in at 3176lbs now (on englishtown's scale), thats with A/C and cragars.

Thanks!

I can't give you any exact numbers off the top of my head, but a V-8 with an aluminum intake, headers, and no a/c compressor will weigh just barely more than a fully loaded I-6. The stock iron intake, exhaust manifolds, and a/c compressor are heavy! Is that a cast iron PG or aluminum case? Them old iron case PG's seem to weigh approximately a ton when trying to bench press one up into place.

travis the glide is aluminum.
I forgot about the headers, of course i will be using headers.

He, He!!!

It may not matter, but that old heavy cast-iron Power Glide can be used to push start your car b/c it still has a rear pump in it that can be ran off the driveshaft!!! pdq67

anyone?

Paul, Do you have any iron intakes you could weigh?
Thanks.

Cast 4bbl intake off a 305 weighs 37lbs.

The net result of all those changes on my car left me at 3120 lbs with a full tank of gas. Never weighed it with the I6, but I am using I6 front springs which happen to make about the perfect ride height with my V8.

Am running aluminum heads, aluminum intake, aluminum water pump, headers, TH350 trans, 8.2" 10 bolt rear end, stock brass 3 core radiator, full stock interior, and no 'glass parts. SSM lift bars and CE subframe connectors would add a little weight in the rear end of the car (like about 50 lbs).

ps. I heard once that the 12 bolt is not significantly heavoer than the 10 bolt. A few extra pounds in the housing and gear set but that's about it. Could be wrong though - you might double check.

When I swapped out my old cast iron 327 2-barrell intake for a performer aluminum some years back, the aluminum piece was more than 20 pounds lighter.

Water pumps... I did this last summer. The aluminum saved 4 pounds or so. Mini-starter saved 10 pounds! If you go with a 'glass hood... the stock flat steel hood on mine weighed 49.5 pounds. Rear seat is kinda heavy too.

Can't say about the AC...

Good luck with the car diet. If you find any more info, I'm interested as well... I'm shooting for sub-3000 pounds myself. Last time I weighed it I was at 3180 with no driver and 1/4 tank of gas. Since then I've changed up a lot of stuff... I'm guessing I should be closer to 3120 now.

cool, thanks guys. Those iron intakes are HEAVY. i'll weigh my aluminum performer rpm later on.

I weighed my 67' with a 1/2 tank

I doubt that the 12 bolt is much heavier, they're very close to the same size, i'd guess 10lbs, becuase the axles and housing are a little bigger.

Anyone know what an 15X8" Cragar steel wheel weighs?
how about a Weld prostar 15x8.

Thanks

I don't know the exact wheel weights, but I remember picking up a Cragar SS wheel once and thinking it was very heavy... the Weld wheels are supposed to be pretty lightweight right?

yeah, i have the cragars on there now, them wheels are like lead weights. Just wondering if anyone had a set lying around without the tire on it.

A complete drum brake 12 bolt weighs 185. A ten bolt might be 20 less.

Aluminum water pumps are 2 lbs lighter
Iron head is 45
Aluminum head is 24 for a -8 Brodix, the later alloy heads are probably a couple of pounds heavier.
I think the 575 lb weight is with cast iron exhaust manifolds and maybe an alternator or generator. Not sure if that includes a flywheel and clutch, but it might.
I'd expect an aluminum head intake and water pump SB to be in the neighborhood of 480 lbs.
This would be with pulleys, water pump, intake and carb, starter, a 15 lb clutch and flywheel which is way lighter than could be run on the street, add another 15 or so for a street clutch, subtract 10 for an auto trans flexplate. No exhaust, PS pump or alternator.

cool, the headers will take off some lbs. thanks for the 12 bolt weight.

Although I haven't heard from anyone with some real world experience. DUI offers a dry cell battery that's around 12 pounds or so. That's a significant weight loss there, too.

True. I'll get into the "nuts and bolts" weight loss after i get the new combo together and get it consistent.
Then i will know what everything accounted for.
I have no plans of moving the battery location though, but a lightweight battery might be a good choice, as long as it can withstand every day use.
