I need your expert recommendations on this one.
I have an 85 Fiero based Lambo Diablo Roadster replica. It original had a 5 speed 2.8L, It ran okay. I had V8 Archie do a 350 sbc swap(I kept the 5 speed) then i had the frame reinforced to address the flexing issues with roadsters, it probably added about 200 - 250 lbs in materials. I also put 18 x 11 wheels on the rears. It has been sitting in storage for about 5 years.
I just tried driving it.
Here is the issue...
When i engage it into gear, I don't get that kick/thrust one usually gets. The vehicle engages softly and moves slowly either in forward or in reverse. I only drove it 1/2 a block. Even if i step on the gas, it doesn't punch it. To make a comparison....it feels like if you are driving an automatic with low or near empty transmission fluid. The car has no punch when in gear. It has a new clutch when Archie did the install. Not sure whats going on.
Any ideas?

Sounds like your clutch is slipping.

Does the engine rev, but the car not accelerate, or does the engine lug?

Yes... The engine revs but and makes a slight difference in thrust.

Thanks to Will, Olejoedad and Fierosound for the quick response. I will have the throw out bearing replaced. I now just need to find out which clutch, throw out bearings V8 archie used.
I assume that is specific clutch and bearing?.

While you are in there.....examine the rear main seal on the engine and check for any oil on the clutch. 5 years of sitting can be a problem.

A bad throw out bearing would make noise. You just need to pull the transmission for inspection of the clutch, then figure out what's wrong from there.

Long shot... but make sure the rod between the slave and the lever on the transmission wasn't replaced during the engine swap with a rod which is longer than it's supposed to be. If the slave is bottoming out, the clutch will never engage completely.

I will definitely have the transmission pulled and check...
1. The throw out bearing as suggested. Even though it does not make any noise.
2. Oil leaks on the pressure plate.
3. Check the rod on the slave Cylinder and Lever.
Is there anything else i should check?
Also...Which setup(clutch, pressure plate, throw out bearing, etc) do you guys recommend for 350 swap? In case i need to replace.
