If its locked up that means the engine siezed. Which means the pistons got so hot they swelled up until they couldn't move in the cylinders any more. I wouldn't bother with it.
will a 4.3l vortec starter fit a 305 vortec?
It will as long as the 305 is a VORTEC ENGINE TOO.
a 350 will produce around 250 hp, and a 305 about 200 hp
Are you asking if the 350 vortec will interchange with the 305 vortec or any 350 with the 305 vortec? The 305 vortec uses a conventional small block Chevy style large starter. The 350 vortec often uses a high tourqe mini starter. You can interchange them. The mini starter is preferred as it saves space has more torque and normally last longer. Now if you're talking older starters interchanging? Some of the older small blocks used a diagonal bolt pattern and different tooth count.
No 305 heads bolt up different then 350 heads If they are 305 vortec they will bolt up. However they do not have the same flow. The 305 vortec head has smaller runners, smaller valves and does not have the same heart shape combustion chamber. Now if you meant the older 305 heads onto a 350 vortce then no they will not. The vortec uses raised runners and the ports will not match. On top of it all the 5.7 vortec has more flow then any other production head. Placing a 305 head in its place would be going backwards.
A V8 vortec could be either a 350 (5.7 liter) or a 305 (5.0 liter), it will say right when you open the hood, i have a 305, the truck is a 97 Chevy 1500.
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
Yes they are the same.
Yes, they will work. but you wont gain power because the little 305 isn't putting out enough flow to keep up with the heads
Yes
dont know I hate you
No. The 350 has bigger valves. While you CAN put the 305 heads on the 350, (I can't imagine why you would actually want to) you can NOT put the 350 heads on the 305. Because of the 305's small bore, the valves on the 350 heads will hit the cylinder block.
