That totally depends on how MUCH MONEY your wanting to spend. Myself I wouldn't spend any money on a 305 engine. I would get me a good 350 engine to build.
yes
A Chevy 305 with a roller cam will have MORE power than a 305 with a flat tappet cam if both are installed in the same engine. The horsepower of any 305 depends on what all is done to the engine. Changing from flat tappet to roller will gain some. There are other ways to increase horsepower and there are other ways to increase torque.
Yes. The HO engine in the Monte Carlo SS had higher compression, bigger valves, and a different cam.
You'd have fewer complications if you stick with 86 and older.
yes most Chevy motors are able to be but in any other Chevy u just have to make sure the the intake system stays the same
yes. the last year of any Pontiac v8 was the 301 in 81. the standard engine in the 82 and up firebirds was the corporate engine-the Chevy 305
Yes. It has TBI (throttle body injection) that is run by the ECM (engine control module).
any Chevy 305 block can be safely bored .060 over. if you have a good block, with thicker cylinder walls, it might be .080 borable.
Honestly, junking the 305 and installing a 350. The 305 is basically an underbored 350. Because of it's small bore, large valve heads can NOT be used because larger diameter valves will actually hit the engine block. The 305 is a good fuel economy V-8, but it simply is NOT worth messing with if you want to go fast. 305's also have weak blocks, connecting rods and crankshafts as well. Ask any engine builder and they'll tell you the same thing. The 305 is good for what it was designed for, but for performance, it's basically junk.
Yes it will fit right on the back of any SMALL BLOCK CHEVY ENGINE from late 1999 down to 1955.
Regular Unleaded 87 Octane is sufficient. Buying any higher octane is a waste of money and will provide no benefit.
