Default lt1 swap into fox body (worth it?)

hi
I have 1990 mustang roller and I'm thinking about dropping a carbed lt1 and 350th in it

can I modify the K-member or do I need one ?

I'm on a budget so basically I'll not modify any thing in the engine can I expect a fun tire burner ride ? the car has 3:73 gears

Just do a SBC, or a LSx. The LTx is too in the middle. ESPECIALLY for doing a carbed setup.

gen1 350 only if running a carb. well, unless you want to go big inches. i wouldn't waste my time and money doing a lt1 swap because the intake is the best part of the lt1 and you will be taking it of to put on a carbed intake.

Lt1 is a waste of time and money, do an sbc or and LSX if you have the know-how.

Yep, the LTx is in the middle. Carbed SBC is the way to go or carbed/EFI LSx for the most but cost the most also.

I know its a Chevrolet forum but, you could put in a stroked 351W in there. I've heard its a relatively easy swap and should make good power.

if i were on a low budget, that is exactly what i would do. either go 351w or stroke it to a 427, but the stroking option is high too. a 351 will really wake that car up a lot. everything would bolt right back in but you may need to run a cowl hood for clearance. if i didn't do the 351w, then i would definitly gen1 sbc.

If your gonna go carbed just stick with a gen1. But personally id stick with the fuel injection on the lt1.

I also agree you should find a 351w. Externally its the same thing as a 302, and will bolt right in.

^I hope that quote wasnt an insult? LT1 is fine if its already in your car but I dont see why you would swap one in when the sbc or lsx option is on the table and easier to do.

Put a 302 or 351 based sbf in that thing, why ruin the damn car. If you don't like ford, then sell it because even with a chevy engine its still a ford.

I would have to agree that a 351 Windsor would be easier but the LT1 is not a waste of money at all. It is newer technology in comparison to an sbc but if you choose to go with a carbed setup you might as well just go with an sbc because it would be easier. If you go with an LT1 keep the intake and fuel injection. People put LSX's in everything I personally think it's cool to try something different and be just as successful.

Thank you all for the responds
I have the car minus engine and tranni I got it for $800 it has fiberglass hood ,3:73 gears, rear coil over ,electric fan, aluminum radiator and fresh paint.
I'm on a budget and yes I don't like ford engines (351w is rare here) so I thought about doing sbc1 swap but again I could find a complete lt1 for $600 around here why not carb one and use it, I'll get more power than sbc1
What do you think ?
here is the car before the hood



I thought a lt1 with t56 in this thing will be cool

Well, the thing is, a vortec 350 with a cam will make plenty of power. Stock for stock, the LT1 did never make more than the best made SBC. There were 350 ci small blocks rated at 370 HP. A LT1 was never so powerful, nor a LT4. Not modified, a SBC with vortecs is the ultimate budget motor nowadays. But if you like EFI, then i guess TPI and TLx injection are ok but since you want to d a carbed engine you are going to have to drop some $$$ on a LTx carb swap intake.

No insult taken i just thought it was funny how you said it, especiallywith the lt1 being the red headed step child of engines. Ill take it off if you like.

But i agree with the guy above, to convert an lt1 to a carb is pretty expensive to do it right. You can get the heads ported and with a big cam make over 400 to the wheels but it must be done right. If you want to stay carbed definitly go with a sbc. people have made massive power with them for years and alway will be. Lsx swap and budget build shouldnt even be in the same sentence.

I love the lt1 engine but i would go sb1 in this instance.

like i said above, the main performance upgrade of the lt1 over the gen1 350 i s the ram style intake which you would be taking of to put on a xcarbed intake anyways. other than that there is no difference between the power of a lt1 vs. gen1. the topend will be the same the way you want to go, so go with a easier to maintain bottom end and be done with it.

You might wanna check on that, Ive never ran an LT1 with a similar setup to mine that could stay within a mile of my bumper. They can make good power but still fall a little shy of an sbc due to the lack of aftermarket research on them, sbcs have been around for 50+years and have benefitted from countless amounts of research and development.
