thanks for the pics jakesz/28 very nice looking setup hows it run I'm sure its really strong ....what size cowl are you running to clear the carb ..

 

my carbed iroc would do that if it was decent out.. once it got around freezing (fall morning in Ontario) you would have to pump it a couple times then let it warm up a bit before giving it to much..

fuel injection works better in wider range of temperatures. again race only carb would be fine..

 

akafred hows your twin turbo setup coming along, youve put in some serious wrench time.

 

works good.. i just blew the power steering pump thou.. i made a reservoir with baffles but it seemed to still foam up. before i got to change it for the third time the pump blew.. going to try to "t" the outlet right into the inlet and see if it works better.

i have also been running with the screen on the maf so i am going to remove it and port it to see if it makes a diffrence. i have a spare if it doesnt work.

 

I would say to keep the FI unless it is going to be a higher reving engine which is more race car then street car. With tunercats it is easy to tune all mild builds and the software is cheaper then LT1 edit. I thought in this build I would have to car going earlier in the year by going carb but money still ran out. Changing jets isn't bad or hard to do but plugging in a laptop just seemed easier.



My car runs rather well for having a out of the box 8896 dominator on it. I have some part throttle tuning issues with it being to rich. I had to lean out the main jets. I might be able to sixty foot better on the motor if it was a smaller carb but then again it does seem to work well so far. The hood is a 3 or 4" cowl. getting an air cleaner on it would have been about impossible if I wouldn't have built the air pan the way I did with an LS style lid.

I went 10.84 @ 126 N/A first time out.

I think it was madaction on here that posted some pictures of a 4150 mounted sidways which would make jet changes easier and faster. I think the only difference in the carb is a different style float.

 

One advantage of the LTx platform is the reverse flow cooling may allow you to run a little more compression and timing verses the first gen block other then that they are about the same either way.

 

Sorry this is OT, but it got me thinking. If I were building a street 4th gen from scratch AND MONEY WAS NOT A MAJOR CONCERN it would be an LX based EFI combo. If money were NO concern, an aluminum block BB. Next on the list would be a big cube Gen I. Sorry to say, but the LTx would be last on my list, except that I already have one, which makes the other options much less attractive.

To get a little bit back on topic, a carbed gen I in a 4th gen F-body makes sense for certain people. Like the OP, who apparently already has a gen I motor. A carbed LT1 does not make much sense to me, not dissing anyone who has done it. But to each his own. I have helped out on a carbed gen I in a 4th gen and it was not hard. A little cutting of the cowl for a low profile distributor and a cowl hood was all that was needed to fit it in and it runs nice. Is the fuel economy as good as EFI? no, but for a car that sees limited miles, so what?

Sorry for the rambling, too much coffee this am.

A carb'd LT1 doesn't make sense to me either because they come with fuel injection already so it doesn't make sense to convert back to carb, at least to me. A gen 1 swap doesn't make sense to me either unless you are going big cube race motor. If you are going for a hot street car or weekend cruiser I don't see the need to switch because ultimately they are both Chevy 350's with just a couple differences. You're not magically going to make 100 more horsepower just because you have a Gen 1 under the hood.

 

I agree with you Rich on the BBC thought I was going to do a dart block but changed my mind for the LTx shoutout that I didn't make it to. I wanted to try and get the first LTx block to go 8.9 on nitrous and this year isn't over yet. One thing about the LTx that some may have forgot is true to the vortec truck motors also. The LTx platform has a better head design then most or maybe even all of the older sbc and the fact that they are set up for a roller cam staight from the factory is nice if your trying to put together a build.
