thats funny you should say that z284ever, i live rather close to you, i live in rockford.

if you want it, it couldnt be all that bad, maybe ill wait to mod/change my intake until im done with the body work.

keep posting though, i love reading your guy's controversial replies

 

As for me, I might be interested in a CrossFire, not because it's easy to build up. I'd be interested in finding one because it's different, relatively rare and I think that they look neat.

 

well, i could email you once i get enough money to change to a carburator set up. how much are you willing to spend?

 

I think that I would only consider Cross Fire Injection if it were in a complete, running car.

But let me know anyway.

oh, you want the whole car? i thought you just wanted the whole cfi set up. im not sure if i would want to sell my car, its my baby! lol, ill think about it though.

 

No, but supposedly a 305 TPI can run mid to low 14's easily. At least thats what some guys in here claim. I've stayed away from 305s for the lack of power. Still, the 305 CFI is like a 305 TBI, running very good they may turn 16's stock. I'd still beat ya with my wife's bone stock Grand Am GT w/a 3.4L. There are guys that get them to run low 14's to high 13's too.

To get back on the original topic. Personally, If you're wanting decent performance cheap, get the carb and intake combo, but only if you don't have strict emissions laws in your state. $300-350 (depending on which carb you get) you'll have an induction set up that can handle most future mods on your car. Even if later you decide to run a 350.

 

and don't forget you'll need a noncomputer controlled distributor, fuel pressure regulator because of the higher output of the fuel pump, and miscellaneous parts like fuel line, air filter, etc. so now your up to about $700 to do this swap. then you still have to tune it in. and you still end up with the same or minimal gains.

now, let's use this money another way.

hedman shorty headers and ypipe = $250
3" catback system = $350
someone to install = $200

now doing this we have proven a 1 sec gain. so, don't bother swapping the CFI on it. do the exhaust first. it'll be the biggest gain you'll get on the car. portig the stock intake gained us another three tenths.

the problem isn't just with the intake. the exhaust is a joke on these cars. (but hey it's the intake that's junk). the heads have 1.72 intake valves. kinda tiny there. so upgrading to say world product 305 torquer heads or say corvette l98 aluminum heads would be a big improvement (but hey the intake is the problem). then the tiny peanut cam in these 305 motors is another cause for such low output (but again it's the intake design at fault here).

 

i fail to understand why people buy 305's and mod the hell out of them. Sure if gas mileage is important to you then get a 305 but then modding the hell out of it doesnt make sense. A 350 will cost about the same as a 305 and especially if youre on a budget youd have to drop 2 grand into a 305 to make it the same as a stock 350....just doesnt make any sense to me

 

simple. because some people don't have $2000 right off the bat to drop a 350 in their car. so, they want to modify what they have. and usually what ever they change can be used on the 350 later on when they have saved the money. but, until then, they want to make what they have better. in our case, we have an 82 vette to do the 350 CFI stuff on.

 

you didnt understand....if you wanted a car to mod i dont understand why you wouldnt just buy a 350 instead of a 305. They usually cost about the same.

 

well maybe that was the car they could afford at the time. or they didn't know any better. either way, it's what they have and they want to know what they can do with it. so instead of making them feel stupid that they bought this particular vehicle, make them feel welcome into the f-body world and help them out.

 

thanks mrr2, i would really like to stick with the cfi as long as possible because of a low budget. also if i do go exhaust first, i could just keep it if i go to a 350. with the exhaust though, could i just go with the headers you mentioned, and instead of a y pipe, us a h pipe and have true dual exhaust? if so what mufflers would i use? and how much do you figure this would cost?

btw were you part of chevyhackers cfi project? if so great job!

 

Black, it is a major pain to run true duals on these cars, I have an Edelbrock TES exhaust system on mine it has the shorty tubular header manifolds and a real nice Y pipe that hooks to the factory Cat, all for around $320 out of Jegs and it is a total Kit all the bolts gaskets and what-not to put them on.

 

mmm....fuzzy math....this is like the presidential elections.

OK, $350 for a new carb and intake. Intakes can be had for under $50 on ebay and swap meets. You can pick up good used Edelbrock carbs cheap too or a rebuilt carb for ~$100. There are a lot of people that ditch good carbs when they convert a cruiser to a racer. Distributor, a working HEI non-computer controlled...$20-30 at junkyard, at a swap meet, or on Ebay. HEI's are a dime a dozen and there isn't much that goes wrong with them. Fuel pump ~$60 for a high output aftermarket unit. You can get a HO stock unit for less. The stock fuel line will work and if you utilize it then your fuel filter will too. You'll just need to modify the fuel line a bit. Fuel line is cheap and is sold by the foot. Even starting from scratch you can buy 25' of hardline for $25. Air filter for a carb, $20 to $40 (stock filter may even work here). Just use your brains and do a little shopping and you can have all this for way under that $700 price tag, even for under $300 if you know where to go.

I built a 350 longblock for under $800 that ran 13.36. I've seen turn key 383's and 377's go for under $1000. You just have to know where to look, and be willing to look somewhere besides the summit catalog or a speed shop. If you live in an area where there are dirt track guys, you definately can find cheap parts.
