The 305 is a early 90 z28 motor. It is a roller motor! So I was always told that the 305 heads were really restricting on these motors, so I figure Id use my fresh double humps 202/160s, my 400 crank "if its not all scared up" and go fuel injection and build somthing that wont be as easy to distroy but still make some power????

I want to do this fairly inexpensivly. I have the 305 short block. I have the 400 crank. I have all the fuel injection stuff, and I have the double hump heads. So I want to use what I have with out buying a ton and still make something fun to drive.

Hmm, using parts only because you happen to have them is not always a good idea. To build an engine that goes fast, and is fun to drive a long time you need to get the combination of parts correct. SBCs are very forgiving when it comes to running at all. Almost any combination will in fact run. But not always well. Consider your needs and the vehicle weight, set yourself a budget and then shop around for parts you need to achieve your goal. If parts you already have fall into this margin, so much the better. If not, keep them for later and buy other stuff for this engine. Building a motor is such a lot of work you don't want to kick yourself afterwards for saving 100 Bucks somewhere along the line.
But that's just my opinion, as always.

http://www.goingfaster.com/spo/modthel03.html Ahh nuthin like a good hot 305 to make em cry,especially when they can still see the block numbers and know its a 305 block. I think the 400 crank in the 305 is a 331.Follow the build ups and you too can spank all these 383 magazine bolt together mismatched combos!!!Speed (rpm) Torque (lb-ft) Power (hp)
