weight savings after SBC and IFS swap

I know this is a very vague question but has anyone ever weighed there truck after an sbc swap and front end swap? The reason being is that I am trying to estimate how much weight I cut off this thing.

Im running an aluminum headed SBC with a no limit tubular coilover IFS. (similar to mustang 2) TH350 transmission and 12 bolt out of a chevelle.

Thank you,

Re: weight savings after SBC and IFS swap

You probably won't be saving any to be quite honest.

Yes, the 216/235 is a heavy beast. With that said, A small block is about 30-40 lbs lighter. With your aluminum heads, you may save another 20-30 lbs. But, are you running power steering, A/C, larger radiator? Those things all add weight, not to mention the TH350 full of fluid is heavier than a manual 3 speed or 4 speed trans.

As far as the suspension goes, the IFS is probably a little heavier. But, most of the weight is unsprung weight so should have little bearing on your spring rate.

Re: weight savings after SBC and IFS swap

Truth be told I'd have to believe that it is minimal. By that I mean within 100 to 150 lbs.

Curb weight on a 51 3100 reads out at 3285 and you could run yours across the scales with half or more of a tank of gas and hit pretty close.

Not Least of all - 36 Lbs for using Centerline Racing Wheels & Right Tire Choice . . Rolling Weight

Another 12 Lbs - rolling weight - moving to 2 Pc. Rotors

Not Counting ( Alu. Brackets , Lightweight Starter & Battery ) - which could get You 24 lbs easy ..

Re: weight savings after SBC and IFS swap

I'd just go to the local truck scale and weigh it. They will usually let you roll across the truck scale at a truck stop and read the weight for free if you don't want a certified printout. Printouts cost between 5 and 7 bucks around here but are accepted no questions by the dot.
