Hello, I'm looking for a rebuilt 305 for an 81 k5 blazer. I'm having some trouble finding one, be it by iether an onlie site or store.

My question is this, where would I be best to look for this (like what kind of stores have this, where in the phone book should I be looking) or if anyone knows of any websites that could help me with this. Also, I have looked ut upgarding to a 350, but have been told that this would require a deal of extra work dealing with throttle and tranny linkages to engine mounting bolts.

Any comments are welcome.

 

The swap should be almost seamless.....the 305 and 350 use the same trannys and mounts...the carb off your 305 should drop down on a 350 intake maifold. The only issues I see is headers, distributer and accesoies....pretty sure the front assesories on the engine should bolt up too....other than that personaly the 305 is a bit of a boat anchore......but if time, tools,knowledge, and coast are a problem then your local race shop or machine shop should have 305 long and short blocks at hand or can get you one resenably quick! Hope this helps
