alright guys, my engine blew up. very sad day. but im tired of this computer controlled ... so im switiching it over carburated. i already got a crate engine that my grandpas is GIVING me. yes its pretty amazing. (he restores old cars and he has like 4 305's and 2 350's laying around the shop so im gonna steal it )it has the heads on it already but no intake. can i use my intake off my engine or do i need a carburated intake? is it all the same or not?? i know the intake will fit on the new engine but i just needa know if the intake will work or not.

and now i need to buy a carburator. what kind of carburator can i go with. ($300 or less). i plan on putting a good cam and new heads on it (someday) so what should i go with to plan for the future?

 

"Your mission, Jim, should you decide to accept it, is to give the OP useful recommendations when he has given you squat on which to base your recommendations. Good luck, Jim."

 

Give us more information: What crate engine, what heads, your goals for future upgrades, etc. What you do now may or may not transfer over in the future, really depends upon what you've got.

 

okay scratch the crate engine idea. sorry i said that a little to early cause i got excited and got my hopes up lol. turns out im just gonna get a complete engine but its only a 305 while i save up to buy a 350 crate. im gonna put the 305 in just so i can drive it. dont wanna 305 but its free so yeah. but i do still need a carburator. im thinkin bout maybe just get a 600 holly. i plan on just porting my heads, getting a high flow type intake, a bigger cam. lookin for about 500 rwhp. should i get a 750 holly?

 

500 gross flywheel HP out of a 305 is a pipe dream. 500 rear wheel HP out of a 305 is completely out of touch with reality.

300 gross flywheel HP out of a 305 is a reasonable goal. But, it depends upon what 305 you're starting with - again, more information required.

Assuming your 305 has 416 or 601 casting heads, go ahead and port them. Put 1.94" intake valves in while you're at it. Cut the valve stem guides for positive type stem seals, get a good set of valve springs and retainers.

Comp XE262 or XE268 cam, Performer RPM intake, 600 CFM Holley, you're at least 300 HP. Plenty of power, reasonably streetable. It will all transfer over to a 350 if you like, now you're close to 400 GFWHP.

 

oh i know 500 hp is way out for a 305, i mean when i get the 350. i plan on buying the carb and putting it on the 305 until i get a 350. so im not lookin for 500 hp for the 305. im just using it until a 350 is available. when i get rid of the 305 ill keep the carb and put it on the 350. so im wondering what carb i should get to handle 500 hp, but still be okay for only 220 hp for now. sorry bout the misunderstanding.

 

500hp out of 305 has been done

is it practical? hell no lol

but why are you ditching efi? efi is so much nicer to have than old nasty out of date carbs lol

but yes you need a different intake....might i add i run a edelbrock rpm performer on my 305 carb's application and LOVE the powerband it makes.

 

because i cant STAND that computer controlled crap. i can work on a carburator and i can ge the max performance out of it without having to buy a program for your computer to set it all up. efi is better fuel milage but come on.. this is a camaro.. when you buy this car your not thinkin about fuel milage. your thinkin bout stuffin mustangs in the dirt

 

You've got a mental block that I'm not going to try to get you over - that's your problem.

It would be nice if you would separate the 305 questions from the 350 dreams. Basically nothing you would need for a 500 HP 350 is going to do you any good on a 305. So, get the 305 running, and start from scratch with the 350.

Although, quite frankly, a 500 HP 350 is too wild to drive on the street as well. Have you ever been in a car with 500 HP?

 

all i asked was should i get a 750 holly or keep the 600. i PLAN on getting my 350 to have around 500hp. i dont wanna buy 2 carburators so i wanted to know if a 600 holly is going to handle 500hp. dont want your opinion and dont really give a crap about your opinion.if i want 1200hp then ill get 1200hp. and its not a "350 dream" its me planing for the future. when i have 6000 dollars to just play with ill buy useless crap that i wont need in 2 months. trying to spend my money wisely. so five7kid if you dont want to answer the question, then IGNORE THE THREAD. thanks.

 

I'm more than happy to answer the questions. I just want to make sure the questions are clearly defined so the answer can be too.

A 600 CFM carb is not enough for 500 HP. A 750 is too much for a 305, although it would probably operate. 500 HP would need more like an 850 CFM carb, which wouldn't work well on a street 305 at all.

If you try to get parts that will work on both, one or the other engine, or both, will suffer.

My "opinions" are based on facts. A dose of reality is what usually draws out what others see as "opinions". In my "opinion", the money that will be needed to make a 500 HP engine ($6000 isn't enough) makes whatever few $'s you have to spend on a proper carb for a 305 moot. To put it another way, if you need to skimp on the few $'s it will cost for a proper 305 carb, you can't afford a 500 HP engine.

 

your right. i cant afford a 500hp engine. not right now at least. sorry for snapping but i just wanted a simple answer and thank you for answering my question. im only going to have the 305 for about 2 months so ill get the 750 holly and ill start rebuilding my 350 this weekend. ill only be driving the car on good days (maybe twice a week) so it wont hurt my engine to bad plus after im done with the engine it will prolly sit in the back of the shop for the next 10 years. by the time i replace everything pn the 350 i may have about 300hp which seems more practical for now. 500hp is to much maybe i was just being dumb. i apologize.

 

Accepted. Just trying to help, and keep a light air about the place.

My Berlinetta #1 has about 375 HP at sea level. I don't drive it at sea level, so the HP is more like 290 here. It's more than adequate. Mild enough to be tolerable, powerful enough to be fun.

Based on formulas in magazines and on the internet converting 1/4 mile data to HP, the '57 puts about 510 HP to the ground on the juice (even at this elevation). I can say without hesitation I wouldn't want to try to drive that kind of power on the street all the time (perhaps even occasionally), even in a heavier car like it. It would be even worse in a NA smaller engine.

But, dreams are a good thing. Keeps us moving forward.

Right now I'm headed to the garage to work on that LS1/T56 dream. . .

 

id like to get that LSX engine

id like to build the 350 up and put it in my current camaro, but at the same time i want to just put a different stock 350 in and sell the camaro and get an iroc with a T55. i like my camaro but i just love the feel of that 3rd pedal

whats your 57 run on the 1/4 mile? my grandpas friend has a 56 (my fav year) and it runs low 11's. no idea whats in it but its pretty quick.

 

It'll run 12.2's at sea level NA. Check my vBGarage for details.

FWIW, it's taken me 37 years to get it to this point. The silver car getting the LS1/T56 is my version of a "dream car". The '57 will always be special, though.

 

im only 18. that prolly explains the 500hp deal lol. and yeah i think in about 20 years my dream car is more than likely either gonna be 71 dodge challenger R/T or the 70 hemi cuda. if i had a choice for the older cars though, i'd pick a 59 El Camino. love them cars. good luck with the dream car. hope everything works out lol.
