Are you planing on building one? Or are you just wondering if they are any good? Although the 305 is a small block Chevy there are some problems with this engine in the way it performs and the way it is built. First off the 305 is 45ci smaller than the 350 and the bore is only 3.745 and that's one of the smallest bore to ever be drilled into a small block Chevy. These are the two main reasons why you can't build a lot of power out of a 305 but, because the 305 have a 4.00 stroke you can build some good bottom end power. The 305 also can only use heads as big as 1.94. If you were to use 2.02 heads on a 305 the intake valve would hammer against the cylinder wall. The 305 also seems to have ignition problems with higher engine speeds. http://www.superchevy.com/how-to/engines-drivetrain/1412-how- to-mod-a-305-with-bolt-ons-add-168-rwhp/

Yes, get something other than a 305 engine and that heavy car. It is likely not worth the money it would take to make major power increases with a low compression 305.


Thank you if there is anymore advice you can give me I'd appreciate it


I love my car and the body style I know the weight is Alot would just like it to be quicker then it is I know dropping money on a new engine isn't worth it that's why I was asking some parts I could get


After all I am surrounded by a bunch of rice rockets
