i saw this thing on the net bout sum 350 conversion kit for 305's...i wanna know if any1 knows anything bout them and what the down sides of these conversion kits are. thanx

 

umm, you cant make a 305 a 350. the bore on a 350 is too big.

 

Is this the GM one?

If so, it's a ZZ4 and some stuff to basically turn a LG4 into a L69 clone except it's a ZZ4. That's basically the only way to "convert" a 305 to a 350, is to unbolt the 305, and bolt in the 350.

 

yea thats the 1...so whats the deal with it?

 

techniqu3: I plan on doing this conversion at some point in the future. You can find lots of information about it here: https://www.spoperformanceparts.com/...119&CATID=1099

As it will say in the description somewhere, this kit is for a 1982-87 Camaro originally equipped with an LG4 or L69 305ci V8 engine and a 700R4 automatic tranmission.

You can't buy the kit at that site, but you can get it at a number of other sites, including GMP Direct.

 

If you're talking about the GM conversion kit, it's been discontinued (I just checked the site). I would do it on your own anyways. You could have a very healthy engine with a bunch of goodies for $5,000.

 

Heh.. There's a limit to where you can use the word "conversion." TBI to TPI conversion, yeah. LG4 to L69, yeah. 305 to 350? I call that an engine swap, not a conversion.

 

Oh who cares what it's called? When you buy the kit from a website, it's called "ZZ4 Conversion." It's more than an engine swap. It comes with exhaust and trans rebuild parts as well.

 

I care. I would never say that I "converted" to a 350 because it sounds awkward to me. Conversion implies changing something--be it an engine, a number, a molecule--to something else. In this case they are replacing the short block, the exhaust, and a ton of other parts..yeah, I guess they're converting it. It still sounds weird to me. You can't "convert" a 305 to a 350, right? You replace a 305 with the 350. Gosh, I hate words.

 

Well, if you boys insist on being boys, keep on arguing. This is the title on the GMPP site:

"10185077 - HO 350 Camaro Conversion"

The beginning text: "Chevrolet engineers have developed an emission-legal conversion kit to insall a High Output 5.7-liter (350ci) small-block V8 in a 1982-87 Camaro originally equipped with an LG4 or L69 305ci V8 engine and a 700R4 automatic transmission."

It's no longer being produced, but stock may still be available.


FWIW, from my Webster's:
conversion - 1. a converting or being converted.
convert - 1. to change from one form or use to another; transform.
swap - to exchange, trade, or barter.

Hmmm, considering the "transformation" in performance going from LG4 to ZZ4, perhaps "conversion" is more accurate...

 

This is one complete what ever! It is a very good price for all the parts you get, I mean right down to sticker on the gas cap. Ask the GM dealer for the instruction book or buy it. The instruction book cost me about $13.00 bucks.

I scanned the instruction manual and posted links to it in this thread. The way the manual is written it's more of a conversion than a swap.
