Folks Of Interest 348 chev.

Can I use a flywheel from a 350 sbc on a 348

 

No.

 

Yes, unless you are talking about one for a cast iron power glide.

Just be sure to compare the balance weight on the crankshaft flange. The flywheel "may" need to be machined to clearance for the end weight. Even B & M used to make this stipulation regarding their old Hydro-Stick transmissions. Also be aware, depending on the diameter of the flywheel/flexplate, there may be a starter motor change in the works. I'd like to have a "W" motor!!!! I am Butch/56sedandelivery.

 

Straight shift flywheel or automatic flexplate? I used an automatic flexplate from a 350 on mine. Works fine.

 

If its a netural Balance flywheel and it will bolt on and the starter still work the answer is yes.

 

I used a neutral balance 396"-427" on my 409"

 

Glad this came up. Sorry for hijacking thread, Ive got 348 with cast iron P.g. I want to put 700r4 in. so i need a 350 flywheel?

 

I also used a "standard", small Chevy flex plate on a 409 that I built.
As noted, it was part of the pile of stuff, when the assembly was balanced (as it should be with any engine combination).

BA, I put a 200 4R in my pickup behind my 348 and I used a 350 flexplate. The 348 isn't externally balanced like the 454 so you can use the standard flexplate/flywheel.
Thats one thing I have come to like about working on Chevys, the interchangeability of parts, quite different with Fords.
