I've heard nothing but good things about swapping the 305 to 350, and am doing it soon. I guess my question is how much of a difference am I going to see with the 350??

 

well if you have a stock 305 right now you probly have somewhere around 175-190 horsepower, and with, per-say, a gm performance crate 350 your lookin at around 290 stock.

 

Simply stated... there is no replacement for displacement. You can get more power more efficinetly out of a 350.

 

huge, the basic bottom of the line 350 is puttin out about 180 horse. Thats what the 305 is getting to the rear wheel. But, spend a little money and you can easy get over 300 horse. Its all in what you want to spend.

 

NO FACTORY STOCK 305 is geting 180 RWHP.....[sm=badbadbad.gif]

 

Well, think about it. It will be more efficient to make power with a 350. For the same amount of money for both motors, the 350 will make more power. Sick likes to dump money into his 305 to make 302 hp. There is a point where you can reach 1 hp for each C.I.D. for your motor.The amount of money to get it there is greater with a 305. 350 has so much potential. We've built a 600 hp naturally aspirated 357 motor for under $10,000. We plan on adding a supercharger later so we upgraded the rotating assembly while we were down there.

 

i may be thinking to the flywheel, but still, not a lot of power any way you look at it.

 

Well the engine im getting is definately a bottom line 350, cheap as they come. My next question is...what would be the first thing you guys would modify on this engine?

 

id do a set of heads , an intake, and a cam.

 

i agree with 83 up there, but with an intake upgrade, you need a exhaust upgrade as well to get the most of your intake upgrades. Headers and a full exhaust to go with it.
