no you cant this is a different style and requires that style of head
The crankshaft has nothing to do with a short are long block. A short block is everything but the heads and intake. A long block has the heads and intake all ready on it, Its the complete engine. You have to put the heads and intake on the short block yourself. That is the difference.
yes ,I have change one out with a old 350 it had lot more power . I used the old heads to with vortec intake you have to slot the four bolt holes .but it will work.
A short block is a engine that has NO heads are intake. Some short blocks don't even have a oil pan and timing cover either. A long block is the entire engine complete.
The 5.7 heads will work if they have the smaller 184 intake valves . Or you will have to bore the block over to get the 194 ,200,or 202 intake valves to fit into the cylinder if not it will lock it up when the valve opens and hits the edge of the block
yes! depending on the block. ie. a 350 or 305 will work with newer heads and intakes. as long as you have the correct gasket. the heads can not be reverse flow. they will not work without modification.
Depending on years that you are swapping around....yes. The 305 heads will raise the compression of the 350 considerably. However, the intake valves are a lot smaller than the 350.
460 long block comes with heads... short block does not
A long block comes with everything but the intake, Sometimes they will leave the sheet medal off, Oil pan,valve covers, Timing cover. A short block will be just the block,crank,rods and pistons and cam shaft, Timing gears No heads or sheet medal.
It could be if it is a big block but a "long block" means it includes the heads a short block does not.
Typically these terms refer to rebuilt engines. And two different ways of ordering them. The Long block comes with rebuilt heads already on the engine, the Short block comes without the heads on the engine.
Short answer is yes. But unless you use the same model intake you will have to "hog out" the center bolt holes on the manifold. This is due to the angle of the bolts. With the holes slotted or elongated it will still seal fine. I owned a '78 Chevy PU with this mod done to it with no problems. buy edelbrock intake and u'll make good power with those heads.
It can be done either way, you can request a long (complete) or short block (minus heads).
