hey guys i was wondering if it is realy worth putting money into a 305 ho engine or not or should i just save up and get a 350?

i wanna know the same thing. My 305 HO screams pretty good stock, but I'm looking to mod it out as well. Any info?

If the shortblock is in good shape (rings, bearings) then it is worth putting in a cam, doing the heads and a set of headers.

Well, that depends on your goals?

What kind of performance do you want?

i woukd be happy to get 400 hp out of my motor after im done putting money into it.
should i do this with a 305 or should i save up and buy a 350

i got a 84z l69 ho t-5 t tops i was wondering how many of these cars where made. if there was alot im going to put a 350 because i doubt that its going to be worth any money. but if there is not it might be just like the 67 z dz302s

400 hp would require Nitrous on a 305. Go 350.

L69 Camaros are not very rare. It is not a collector piece.

Whats your 0-60/ and 1/4 mile goal?? Not predetermined HP, the 305 H.O. is a good engine.

so there is alot of them out there

That can be a dangerous question around here! This is an issue of common debate! You're gonna basically get a few answers:

No replacement for displacement

It'll cost much more to get the same power level from a 305.

305's are boat anchors.

305's are great.

I've seen a lot on this debate!

Etc......

My opinion, the 305 is a pretty good engine. I have the LG4 (slow) version in my car, and it is fine for a driver. Now what I really don't like is that my Intrepid with a 2.7 in it would most likely whip all over it (reason for putting a 350 in mine, plus I don't drive my camaro much).

What it boils down to is how much you want to spend, will you be driving it everyday, and that sort of thing. One thing though, if you do start bolting on a bunch of stuff, most all of it will work if you ever do decide to go with a 350. A few exceptions are header primary tube sizes, carb, and that sort of thing.

Hope I help!

headers should work and if ur using a 600 cfm it should work

Is an easy answer to your question: (I'm sure you have all heard this)

How fast do you want to go and how much $ money $ do you want to spend????

Figure that out and it'll make it much easier for all of us to help you out.

I have 2 305's that run very well, but I am gonna yank one here shortly in favor of a 355.

yeah i was actualy pondering with keeping this powerplant being its already3/4 chrome and putting a blower on it and a 150 hp shot kit in the end what will a good blower cost me {a loud one} and a 150 hp shot kit. this is realy what i want to do. ill have the money to do it so it not a prob but this sint till next year. so all in all how much will the blower cost and the nos kit that wat i want to know and about how much hp should i be putting out with this set up.

Keep in mind that all the chrome stuff will still work on a 350, besides, a new engine will be clean and the chrome will look even better!

BTW, I run with 350's all day long in my 84' L69.

Sure you CAN make the 350 faster for less money, but that only applies if you already have both motors and the cost for the blocks doesn't count. Since he already has a L69, not a 350, I say work with that. 13's N/A are not that hard at all.

Sitting Bull how many HP do u have and whats your 1/4 mile??? thnks

I have about 300 hp and it will run mid-14s.

I should correct something I said earlier. A 1986 L69 Camaro IS rare, less than 100 made.

Too bad you don't have the T-5 3.73 setup, you'd be running faster than that. Shoot if i had your heads, I'd have potential for mid-low 13's. I run low 14's now with major traction issues and about 270 hp (my estimate on hp).
