Weight of 454 going to drop the truck even more? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

muthstryker · 10-01-2010, 01:53 PM

Hey guys,

Was wondering how much the front of my truck is going to drop If I was to drop my new motor in with the suspension I have now. Im worried that the new added weight (almost 350lbs more) Is going to drop the truck even more then what it is now, which would render the truck undriveable. Should I wait to drop the new motor in untill I have the new suspension?

Have a couple of your buddies stand on it that weight a total of 350 lbs. See how it looks. Turn the steering wheel. Maybe even drive up and down the driveway or something.

Ha! I didnt think of that, great idea! Thanks alot man!

I didn't think a big block weighed that much more. I thought it was less than 125#?

muthstryker · 10-01-2010, 03:41 PM

I looked up the weights of the 305 and the 454 and the difference was like 350 something. The 305 came in at like 600ish and the 454 was like 950 or something..

muthstryker · 10-01-2010, 03:43 PM

Uhh i think you were right.. I dont know where I got 350 lbs from. Hmm It looks like around 120-140lbs more then the 305 depending whats on it.

*nbpro* · 10-01-2010, 03:49 PM

one of your buddies then lol

3r!c84 · 10-01-2010, 03:56 PM

so from going from a 305 to 400sbc wont add much weight? if any

BigBlocksRule · 10-01-2010, 05:15 PM

305 to 400 won't add a bit, might even drop a pound or two.

STOCKISH · 10-01-2010, 07:29 PM

I swapped a BBC in place of a SBC and it didnt drop more than 1/2 inch.

Hottrucks · 10-01-2010, 08:08 PM

I took out a 283/th350 and put in a 500 caddy /th400longshaft and I run 5lbs more on the air for the same ride height

willett · 10-01-2010, 08:44 PM

never done the swap myself, but i have heard that a suspension upgrade is necessary

STOCKISH · 10-01-2010, 09:03 PM

It's not, you're fine. Might drop a little but you're going to run the Porterbuilt stuff. Your ride height will be adjustable anyway!

DubDubU · 10-02-2010, 10:42 AM

Mine dropped about an 1" to 1.5". It had a 305 also has some rake that transfers a little more weight to the front.

actaully, i think im not going to run the porterbuilt stuff. I saw scottshotrods IFS set up, they have everything I want. Rack and pinion, narrowed track, centered wheels, ect ect. But with coil overs, its what i really want.

STOCKISH · 10-02-2010, 03:07 PM

Well, with coil overs it'll still be adjustable so you can dial it in perfect. Unless your springs are junk, you should be fine to run it like that for a while. Like I said, I swapped my small block for a big block in a different truck and it didnt drop but almost 1/2 inch.
