what can the typical small block h body weigh?

[shytebucket]

My Vega is similar to L79racers: aluminum headed sbc, plastic front seats, no rear seatback, no heater, no spare tire, no cage/frame ties. You get the idea. Last time I put it on a scale it was 2560 with 4gal of gas and 30lbs of nitrous hardware. It doesn't look stripped down, but all the niceties are gone. With a V6 your goal can be reached depending on how far you're willing to go.

Well if you are serious about weight loss (on the car) you really need to look at just about everything and see what you can either eliminate, replace with aluminum components, drill "lightening holes" etc. Keep in mind every little bit adds up, it may not seem like anything but when you throw it all in a box and weigh it you'd be suprised.

There is alot you can do along these lines.

well i know what kind of power my motor makes and mathmatics are telling me this thing has to be 2550or less to run what i want it to. its a shell now so at least i can dictate what goes back in!

[L79racer]

My car only has what it needs to drive on the street. No heater, radio, rugs. Front center bumper support removed. Plastic fuel cell. Centerline rims are very light with front race tires that are light also. If it had a chrome moly cage I think it might come in at 2650 !!

Ha ha ha......... you guys know I had to chime in on this one.

You want light weight, eh? My aluminum Buick 215 weighs in at about 320 lbs from flywheel to fan. A full 300+ lbs lighter than an iron SBC from flywheel to fan.
I have three of these babies and the most I paid for one is $250.

Granted, I'm only getting 200 hp/240 ft-lbs torque in this current form but when I stroke it and/or go with a larger bore block, I should be able to get 250 hp quite easily.

Let's see.... my car weighs somewhere around
2000 lbs(stripped) - 2300 lbs(fully loaded '72 GT).

Let's say 2300 lbs divided by 250 hp equals 9.2 lbs per HP.

Compared to a 3000 lb car with a 350 hp engine getting 8.5 lbs per HP.

Sure, I'm lacking power but I can turn and brake much more effectively. .... which makes for a whole different kind of fun.

OK...... I'm done here.

Hey
Does anyone know the largest displacement aluminum rover v-8??

[custom101]

4.6 Liter, and the last ones were made in 2003 or 2004.

[bill1978v8]

My LS1, 346ci weighs in about 390 to 400 lbs dressed out. Granted my Monza weighs more than a Vega but it still should weigh under 3000 lbs but it makes 345 hp at the flywheel. LS6 intake, dual exhaust, and a computer reflash and I'm at 360 to 370 at the wheels.

LS1........ YES! Hard to top that.

But for those of us on the CHEAP...... here's some Buick/Rover 215 info:

http://lotus.www.50megs.com/V8articles.htm Some basic history, specifications, etc of the GM 215, mods for performance, VEGA SWAP, racing configurations, etc.

http://www.aluminumv8.com/ D&D Fabrications. Been doing VEGA SWAPS since the early 70's. Article on stroking up to near 300 cubes. Near Detroit. The best stateside 215 specialists in my opinion. I've been to their shop.... nice. This site includes their catalog with prices for anything 215.

http://www.v8engines.com/ More performance info than you can imagine. In the UK but all their development and research applies over here. Fuel injection, carbs, intakes, heads, etc...... articles, testing and tuning, etc....

http://autos.groups.yahoo.com/group/215V8/ Lot's of 215 info here on Yahoo groups. It's free to join and there are numerous other groups you can view. Cosworth, other H-bodies, etc.... you name it.

http://www.roverv8engine.co.uk/index2.htm High end Rover mods $$$ 6+ liters..... tubocharging...... computer chips...... etc Just throwing that one in for teasing.

i gather your,s is all aluminum ?

[bill1978v8]

Yes, it's an all aluminum Gen III smallblock with fuel injection. They are coming down in price so a swap could be done for around $3,500 to $5,000. Mine is bolted up to a turbo 350 but you could bolt up any trans that fits a Gen I smallblock. I like the 215 v8, it's a cool combo that is light and powerful. The V6 is also a good choice for cheap power.

really shit i know of a LS1 short block and a set of heads , if i did that swap i,d go with the carb set-up , no need for the computor and all the efi stuff , i,m old school for now LOL

[bill1978v8]

If you go the carb route it's even easier and cheaper!

You can remove the heavy side impact protection beams in the doors, but then you'll need a roll cage which might be more weight than originaly removed.

Looks like you have a sunbird in the background.

Should be a tick lighter in the front than a monza.

I'm sure you could get down to 2750 easy with that light little v6 installed.

loosing 250 is going to have to be done like Cylde said, shaving metal way wherever possible.

[shoebox1.1]

well im not too worried about it anymore due to the fact i have decided to eventually go single turbo on my v6... should make 520+ rwhp @14psi so 100lbs here or there isnt going to make much difference then. im building the car now for straight motor we will see what it comes out too.

[dragmonza]

My Monza with the interior gutted & only a fiberglass hood & ladder bar suspension in the rear weighed 2670 with me and fuel.
