Do a search.....

Why not get a 350? A 350 can be had pretty cheap, slap on a full exhaust, cam, high flow heads and you will be over well over 200HP.

a 350 is too expensive for my budget, my friends taking out the engine so rebuilding it at the shop will be real cheap $300.

Convert it to a roller setup and a set of vortec heads should help it...

That's sounds way low for a rebuild.

are you lookin to spend 300?? ive found a 350 as cheap as 150$

BTW, whats wrong with the motor that it needs a rebuild?

If you're carburated, a good cam like the Extremes from Comp and a Performer RPM or Z28 style high rise along with good exhaust and gears will really wake that car up. mine ran mid/high 14s with no off the line traction @ 96 miles per hour with only mods like listed above and some good tuning. Heads will help a lot, but the $$ will add up fast.

That's a very good question.

If by "rebuild" you mean "adding stuff", then you can do this without pulling the engine. I.E., cam and valve springs will get you to 200 HP.

But...

That's assuming the exhaust is up to the task. And, stock LG4 exhaust is not up to the task. The bad news is $300 will not cover what you need to do to the exhaust to get it up to the task.

-the engine is just too old. and i want it new. and runable. i want to rebuild the actualy engine not add cams and bolt-ons, thats after i get it running. thanks for the help guys please post more help.

or can i get a 383 stroker kit put into the 305??

a 383 stroker kit is only for a 350. NOT a 305.

Not only that, if u did have a 350 and wanted to go 383, its going to cost a hell of a lot more than $300.

You should add a cam with lifts and valve spring to hold the new lift and that should help you get closer to you h.p. goal. There are even cams that work with computer control set up in case you have that set up
