Block swap
Block swap
ok...my lt1 took a turn for the worse a while back and its been sitting for a while...it was initally thought to be a broken timing chain and ended up being that along with a bunch of other broken parts....somehow ive found, a 355 for a really good deal but it is not an lt1 block. what would be involved in stuffing this in my car? any ideas?
im not looking to have a FI car. im not really looking to run the comp. am i gonna need to swap new gauges in? is there any way to wire the old ones up? i need the basics of what im gonna need here so i can get a idea of what this is gonna cost before i start into this project to see if it is worth it.
also im looking at a set of dart 230 heads wieland intake and ~750 cfm carb does this sound about right or am i way off?

Well, while you can make anything work with anything; the truth is that in any PRACTICAL sense you can't bolt GenII heads onto a GenI block.

Depends on what you want. For one thing, if you have enough motor to actually USE a set of 230 darts, then 750cfm is too small. Or actually, let me rephrase that so the ankle-biters don't get bent... If it were MY engine, and I had the displacement and cam to actually USE a set of Dart 230's, I'd be looking at 4500 series carb. Probably a 1050 Dominator.
Look, you want the truth...?
Probably the easiest and most cost effective thing you could do would be to do a rebuild on your existing block, assuming it's not cracked or otherwise damaged. If not, buy a new short block or even long block and bolt your other parts right onto it.

well...thanks for answering half my question, but i thought it was obvious from asking about different heads, intake and carb, i was not planning on using anything from the lt1...now for anyone who isnt going to tell me to put an lt1 in it it would be nice to see what all is involved...im not saying the lt1 isnt an option...im just exploring this avenue to see how much i dont know about what all id have to do. for the sake of arguement lets say the lt1 is cracked. how hard would it be to put a carbed 355 non lt1 block in a 94 formula and have everything throughout work like it should?

ok...great...so do you have anything useful to contrubute besides obvious knowledge? like maybe why the 230 heads are a bad choice. or why a 1050 dominator would be necessary.

Lighten up Francis.

230 Heads:
They aren't a bad choice on their own. They're just big heads. With the right short-block underneath, the right cam inside and the right air/fuel delivery up top they'll make a lot of power. I'm just not sure you appreciate how big they are.
Dominator:
The 230 heads move a lot of air. If you used a set you would want a carb that could keep up, wouldn't you? People often disagree on the appropriate size for a carb, and some folks might think the 1050 is a bit on the big side. However, once you consider the amount of air a 230 head can move, plus the annular boosters that I personally consider to be indespensible, I think it's just the right size.
So now let me turn it around on you...
Precisely what sort of short-block did you intend to put those 230 heads on top of?
Re: Block swap
If you guys want to have an "Advanced Tech" discussion, go for it. But if all this post is going to be is a bunch of attitude on both sides, its going to be shut down. I typed up an answer, but then decided not to post it because I figured it would be met with hostility and sarcasm.
Lighten up, or it gets locked.

that movie rules
thanks for answering the questions...you guys gotta remember that telling someone you wouldnt do something and not giving a reason sounds like arrogance and isnt appreciated as helpful advice. as for what kind of shortblock im putting it on as of right now its going to be a 355 with in the area of ~10.5 comp...less or more when i put the bottle or the charger on it though...not sure which pistons to go with...either way im fairly convinced this wont go into the formy easy so im looking for another car to stuff it in.
as for why i want to do away with fuel injection...thats not really the case. i just found a entirely different motor for a great deal and didnt want to put the lt1 intake on a good set of heads.
