  • Standard (STD) size for stock crankshaft journals
  • Engineered specifically for Chevrolet 400 V8 engines

So far so good. Now if the part fits it'll be great!!

Received just what I ordered in just a few days. I can't review the tires yet because I haven't put them on.

Good price on the fuel pump, and reasonable shipping rate. Now we'll see how soon it arrives and if it's a real walbro not a knock off.
