hi guys I am new to this site and I have a 1989 rs with a 305 TBI I want to build about a 300 horse car just something to play with but help me out with some suggestions what to do 1st so far I have headers catback exhaust and each thing you tell me can you provide how much power it adds or should I just put a 350 in it. thanks for your help

 

your one of hundereds wanting 300+ horse out of their 305. Its possible, many people have it, but its a bit more difficult than with a 350.

First thing you need to ask is how much you wanting to spend?

THEN ask how devoted are you to keeping that 305?

 

well I have money don't really want to do a 350 swap is it hard to do A 350 SWAP?

 

Well yea it all depends on money, time, and your personal abilities. When i say money well you could spend 3 grand on a new 300+hp 350 engine(if uchoose new, i would)plus about 500-1000 on a mechanic to swap it in. And when i say time you could over time build-up the 305(what im doing), and when i say personal abilities i mean how much can u do yourself. So to some it up if you want to go with a 350 your looking at a decently big price. It's good your already runnin' a full exhaust that puts at a little over 200 hp now.

but if you choose the route of beefing up the 305 you could do the following: world products torquer s/r heads (good for 30-40hp, about $800), comp cams xtreme energy hydralic flat tappet cam(good for about 10-20hp, $125/costs over 500 tho for installation), you'd need to get an upgraded chip if you do a cam(mayb small horsepower increase, still a must with cam), edelbrock performer tbi intake(i've heard mixed thing about this maybe an increase of 10-20hp, $230). -OR- you could go with vortec style heads (give u more hp, but a bit more expensive and you'd need the vortec intake)--as far as bolt-ons for the 305 thats about it. And you could always thro a shift kit on their, and mayb some high ratio gears (3.42 or 3.73), and a torque converter(with 3000 stall) all of those would greatly increase acceleration and launch u out of a dig. And some suspension mods to put more hp to the ground (sub-frame connectors, etc) Hope that helps the above is what i plan to have done in about 2 yrs. Im ahigh school kid with a low income lol.
