No. The length is ok, but the journals are different.

It's usually screwed into the intake manifold towards the front, near the thermostat housing.

For the purpose of installing a distributor, remove the coil wire, remove the number one spark plug (drivers side, first one up front), put your finger tightly into the number one spark plug hole, have some one jog the engine over with the key a little at a time until you feel compression coming from the number one spark plug hole, stop at that point and turn the engine by hand clockwise until the mark on the damper lines up with "0" on the timing scale. This will give you TDC for the number one cylinder on the power stroke. This is where you would drop the distributor in with the rotor lined up on the number one position on the distributor cap.

For cam timing,A degree wheel and either a piston tdc spark plug stop or piston stop with head off. remove spark plugs. With degree wheel mounted on the crank,manually turn the engine over until piston 1 is close to TDC, distributor cap/rotor will get u close. put the degree wheel/pointer to 0. Install stop Turn the motorover by hand until the piston touches the stop, mark the degrees. Crank the engine in the (opposite direction 1+ complete turns)until it touches the stop. Marker the degrees down, add the 2 number(degrees before 0 and after 0) divide by 2 and that is the degrees# before/after 0 the piston should touch the stop. An example: if the piston touched 24 degress before 0, and again 20 degrees after 0. You need to adjust the wheel so it 2 degrees, so that the stop touches at 22 degrees before/after 0.

Because of the 305's small bore, you're pretty limited. Large valve heads (2.02/1.60) won't work on a 305 because the valves will hit the block itself. If it's an older 305, your best bet would be the old power pack 283 heads. They flow better than the older 305 heads. Now, if it's a vortec engine, you probably won't do much better than what it had stock. If you are really trying to go fast, the best thing you can do is junk the 305 and replace it with a 350 or a 327.

Depends on the year, but the 305 used the AC Delco R44t for years.

305 327 350 400 283 with a little modifications

The HO engine had higher compression, bigger intake valves, and a different cam. Also, it was painted black.

A lot depends on what year you're working with. Perhaps you could restate the question to better explain what exactly you want to do.

yes

NO. They are different. What you need is called a high rail cylinder head. It must be newer then a 1987.

The trans will work, but you'll need to obtain the correct bell housing.

YES.

you could put a blower on a 305 and a 350 with 10 to 1 compression w 2.02 valves and a stock quadrajet carb willhumiliate it sorry i went through 6000. wasted on my 1977 camaro lt w/ 305. the motor is nothing but a boat anchor. if you want to have real power order a crate 350 with a stroker kit the 305 just wont cut it i had heads cam pistons steel crank headers and a holley blower with nitrous if i got over 340 hp it was sad with all the goodies, and my friends stock 350/350 chevelle would burn me every time. so i gor so fed up i built a 427 and started running mid 10.s

To answer the question, your engine would probably not see much, if any, increase over stock hp. 305's had 58cc chamber heads with small valves. This kept the compression up, and improved the low speed air velocity for good low-end torque. The 327's had mostly 64 cc heads, which would lower your compression ratio, and bigger valves, which would improve high speed breathing at the expense of the previously mentioned low-end torque. Also, depending on the cam, you could have a problem with valve to block interference since a 305 piston is a lot smaller than a 327 piston.

305's don't respond to the same performance enhancements as a 350. You can increase the compression with better pistons, change to aftermarket heads and cam, and get the engine up over 300 hp, but the block just isn't made for any more than that.

32 to 34 degrees

The headers for a 350 and 305 are the same.

Should- I believe they are the same length on all Chevy sb. Since they are dirt cheap you should consider a light weight pushrod, high flow mech pump and upgrading your ss lines from 5/16's to 3/8's.. It makes a diff at high rpm.

You'll need an adapter to put that trans on that engine. Check with these guys: http://www.advanceadapters.com/

307 pistons are 3.875" diameter. 305 pistons are 3.736".

It might be possible to bore a 305 large enough to accept the 307 pistons, but the wrist pin location would be .230" off because of the different stroke.

In short, no.
