Anyone know were you can look up your vin number for free and see what motor and ect.

The 1988 to 1995 truck,the 8th vin K is a 350.I am not sure on the 305 and 4.3.

305 is H, The 4.3 is Z. The RPO codes on the sticker in the glove box will tell you much more than the VIN number.

There are many sites that can decode the RPO numbers. Best bet is to use Google or your favorite search engine to find them.
