CHECK your tioming - might have jumped a tooth - check control module or coil might be the problem
That usually means it's lean. Check all vacuum lines and gaskets for leaks.
It will fit, but you might want to have the crank, rods, and pistons balanced first as there is a big difference in the weight of a 350 piston versus a 305 piston. Wouldn't want to get it all together and have a nasty vibration at certain speeds.
As long as the 350 block is under the year 1986. Then all of the external engine parts will interchange. The heads and intake will also interchange. The CRANK AND RODS AND PISTONS WILL NO INTERCHANGE.
no
No difference in the engine. It is all in the trans and the rearend
All 350's will bolt up to a 2004r if it has the Chevy bolt pattern.
The problem will turn out to be either fuel delivery, ignition (spark) or compression. If all three exist in the proper amounts/timing... the engine HAS to run.
All 350's are internally balanced.
take out distriburtor and turn all the way around make sure number 1 cylinder is all the way up same thing happened to meAnswermine was actually the number 6 &8 spark plug wires were crossed made it backfire through the carb
yes
They are all the same size.
All the dimensions are the same, but it should be re-balanced for the lighter pistons.
