Weight of a s/b chevy

Morning Hambers, Hey i was wondering if anybody can help me out with the weight of a sb chevy. Doing my front suspension and dont have one sitting around to throw in there to see if im close. This way i can just stack me and a few iron parts on there and guess. Thanks for your help Scorp

 

approx 575#..

The problem is there are so many variables. Blocks can vary several pounds due to cubic inches and casting, same with heads. Then factor in the weight difference between aluminum aftermarket parts vs. factory ones.

I have a factory 283 4-jet intake that thing has to weigh 40+ pounds. I also have an Edelbrock performer rpm air gap....maybe 6 or 7 pounds...

I ran performer rpm aluminum heads on my little pickup, they were VERY light...I don't know the exact weight difference, but I would venture a guess at 20 lbs + or - PER HEAD..

Things like that make a huge difference. Make sure you account for all the goodies you plan on running when you are estimating.

575 Sounds like a pretty decent starting point to me too, but I would say my trucks engine after it was all said and done with lightweight parts was probably in the 475-500 range.

hope that helps,

Scot

 

If you can just go to a junkyard and find a junk engine that isn't fixable and hollow it out. That way you will know where to put your mounts and such. You could always add weight to make it where it shoud be. They also have those plastic mock-up engines. I just use a hollowed out engine and a muti-patteran bellhousing for mock-up.

 

I have a windowed 327 block I use to mock up. 575lbs is a pretty good number for an all iron SBC. Aluminum heads and intake can drop that weight down to just over 500lbs.

 

Thanks alot guys this will help me, The motor im planing on will be iron heads and an aluminum intake, no power steering or a/c, This is a Rat and Rats dont have any of that junk!! I dont think any way Thanks so much for the info Scorp

 

550 is close. You do realize this isn't a rat site?

 

What if a rat is the best that you can do? Can we still read and hope?

 

Why are you guys so **** about the word rat?? Lets all jump on the band wagon. Rat rods are bad!! give me a break. The Rat rod term was fine to use till everyone on this site started crying. Now more people are snubbing their noses to the word. What would Rat fink say with all his rat rod pictures?

 

If building a Rat Rod is the best you can do...I think its time for you to get a new hobby!!!
