Are you being a smartass Gunny, or are you serious?

 

I have done several 305 -> 350 upgrade projects over the years. One of the cheapest, easiest and most fun upgrades I have done is to yank the stock 305 for a new GM "Targetmaster" universal replacement 350. It'll cost you $1300 complete to your door and comes with a warranty. You bolt on your intake, front end accessories and drop it in. It's a true bolt-in that a first-timer could tackle with a little help from a knowlegable neighbor or friend.

Rated at 250 HP, which is quite a bit more than any 305 of that vintage. And trust me, you WILL fell the difference in the seat of your pants. It'll be NOTICABLY faster than with the 305. And you can still run it on 87 Octane, it'll still get decent mileage and it'll still pass emissions if you tune it anywhere close to correct. It's also a very easy engine to upgrade later- better heads, bigger cam, etc. Just about anything you do to it will make it even faster.

 

thanks for the info but ive decided to stick with the 305 and just get parts for it. these are some of the things im looking at:
- exhaust
- headers
- camshaft
- carburator
- intake manifold
- cylinder heads
what else should i look for and what companies should i look at to find these parts?

 

Save your money and use your current carb. Nothing wrong with it. If you get anything else, you're going to have to get a different distributor, too. And you won't make any more power than you would with the stock carb for all that money spent.

Cylinder heads - up to you. I chose aftermarket, but re-doing your stock heads is viable.

 

Damon and five7kid are trying to steer you right. They know their stuff and are showing you how to get the MOST hp and value for you hard earned dollar. Spending $1500 on your 305 doesn't make much sense when you can get a brand new 350 for $1300. See?

Sticking with the 305 is OK but ONLY if you stay with parts that will transfer over to a 350 when the 305 croaks.

Stick with parts like those in my sig. That will put you in the mid-14s easy. And follow the link at the end of my sig for a lowdown on how to hop-up your stock heads

 

I think \Camaro83/1011 is on the right track. In fact.. that is THE track to power.

 

Anyone here got a berlinetta? or a 305? and race, wether on the track or street and if you do how well do you do?

 

Yes, yes, and yes (track only, that is - I am a strong non-believer in street racing).

I don't race the Camaro regularly, but based on observed performance, weight as measured at the track scale, and generally accepted formulas for converting track performance to HP from the times I have had it out at the track, I'm putting about 250 HP to the rear wheels. With a stock computer-controlled distributor.

As for how well I do - that's a little hit & miss on any given day, but I'm headed to Pomona next week for the NHRA Summit ET Finals in the Sportsman class.

 

thx 85 305, the only reason i know what i want to get is cause i guy i work with has a 97 z28 with over 500 hp

 

Wow.. that is a very impressive number. Of course, it is not like it is a hard feat to accomplish with that LT1 of his.

 

ya he says he can do the 1/4 in under 12seconds. but anyway what are some good manufacturers to buy those parts from?

 

Well.. what kind of parts? Name your parts, and I will name your manufacturers

 

I would hope he could run the 1/4 in under 12 seconds since a lot of my friends with LT1's run in the 11's with under 450hp.

 

You better keep in mind that you will also have to beef up your tranny and maybe even your rear end. It is a head to tail project to safely get 400 hp out of a third gen and actually keep it running.

It is a LOT cheaper to hold yourself to 350 gross hp and not have to overhaul the tranny and rear, too.

350 hp will get you nicely into the 13s, which is a fast car by anyone's standards.

 

I would suggest AT LEAST a rear end cover that has screws to hold the end caps in place
