Opinion on Swap
 
Currently I have a stock LT1 Motor in my car, with a seat of headers and exhaust. I am contemplating swapping out the fuel injected motor for my built Chevy Small block 355 makes about 450, BUT its carburated..

Would you swap out ease and drivability of fuel injection for an old school carburated motor?

"ease and drivability of fuel injection for an old school carburated motor"
LOL. Carbs worked pretty good for about 100 years. I think one will still work just fine on the street for another year or so.

You ask what would I do.
I would swap it for a real motor. A big block with a big fat carb.

I don't think there is a "right" or a "wrong" here, it is all about what you would enjoy working on and driving. I have a LT Camaro Z28 with a build stroker engine and I'm running the factory EFI. It is a fun car tp drive and I enjoy all the high-tech stuff that goes with it. Have you checked-out the LTXtech.com web site?

I also have carbed tube-chassis drag car and I really enjoy working on it and racing it.

the only reason Im thinking about doing the swap is for simplicity..The carb motor is fairly simple to work on. The LT1 is a pain in the ass to work on and tune, and has too many electronics to chase down gremlins in my opinion. Plust the poor design of the Optispark and distributer being right Under the water pump scares me a bit.

I came out of a high tech Import previously. I had a Nissan 350Z that I built and tuned and it would run 10.0@138, but when stuff went wrong it was a bitch to trace the problems with all the computers..

Currently I have a built 355 small block(10.5 Compression) sitting in my garage that was built and made my 81 Camaro go 11.67@115. I sold the roller and am thinking of dropping that motor in my 65 Merc, and perhaps hitting it with a 125 shot. That motor has a nast street cam in it and sounds mean as hell!!

Plus i love the look of the Carbs and tunnel ram intakes!!

Sounds like you already know what you want to do. I would go with the carb because it's more straight forward and as stated, fewer gremlins.

Sounds to me like your WIFE made up your mind! lol just kidding cause I'd probably be in a lot better shape if I'd let a women make up my mind for me more often.
I would go with a carb if it were me, simply because I don't know much about fuel injections and carbs are just simple to fix or replace.

Let me tell you, If i listened to my wife 100% of the time, I would be ALOT better off..lol All the money I wasted on cars, I could have paid for a divorce..lol hahaha..Seriously, thanks for the advice that the way Im leaning..


One question, my car right now has I believe 2 electric fuel pumps delivering 40psi at idle, Im assuming I would have to remove them and add a pump set up for carburated motors??

Incognegro 11-06-2010 06:50 AM

BTW this is what I came out of...I went form domestics back int he days, to Imports, and back to domestics;This Nissan would go low 10's all night!!!I would drive it to and from the track (unless I broke..lol) and had cup holders and air conditioning..hahaha Everything was all off the shelf parts available for it, except the tranny, we adapted a TH400 for it..Best thing EVER!!! but when things broke!!!EXPENSIVE..

Example-Domestic high end cam $250 Nissan cam set-$1300

If she were your wife,you would let her have her way too. :)

Just to bump this up....I have decided to keep the Comet and drop my Carburated 355 in there and remove the LT1 from it. I am compiling a list of what I will need to do the swap and need your help.

I know I have to change the following:

Fuel pump- Currently I have an after market electric fuel pump which is High pressure. If I am correct I believe I will need to go with a lower pressure fuel pump and regulator for Carburated cars. Correct?

TQ converter- I have a pretty hot cam in the 355 and currently the tranny has a 2400 stall, Im guessing to go with a 3000 stall?

Distributer- I would like to replace the OEM distributer in my 355 and install something with a rev limit and 2 step. Any recommendations on that?

That seems about it for now...

Oh and one more question, will Headers from the LT1 bolt right up to the Gen I motor??? Or do I need headers?

heres another option in my opinion go with a professional products projection III its efi in cab looks learns on go and not as much b.s. as a factory system then you have classic sbc classic looks modern efi driveablity

If I had the $1800 for it I would..

Incognegro 12-09-2010 07:39 PM

That system does look very nice!!! I think I will eventually add it.

Do you know if the headers are the same? Im liking that fuel injection set up and that company makes a really nice distributer too if you watch the video on their site..

for the headers I would try this forum for that answer. I have heard that sbc headers do fit the LT1 but dont have personal experence with it. http://ltxtech.com/forums/content.php

i beleive headers are the same its the ls that are diff
