Hey i wanted to get all of your guys opinion if i should buy a lm7 long block but is missing one of the valves on one of the heads. It has no accessories its just the long block the guy is willing to let it go for $150 does that sound like a good deal or would it be best to find a parts car for the swap.

Heads are worth that much

Buy it, but dont expect it to last 100k as-is

ok so its a good deal, and yes i am aware that it wont last 100k unless i rebuild it

what else is included? the little stuff adds up real quickly. i bought an ls1 longblock for $300, but it had nothing but heads and rotating assembly. i ended up buying a 5.3 for another $300 just to get the sensors, covers, etc.

that is a great deal, just be ready to get the budget together for everything else too

Just the long block but he said its missing a valve in one of the heads, no accessories or sensors

I would hold off. That is a good deal to someone that already has a swapped car and the motor grenaded an they just need another block to use. But you can get a complete motor with accessories and sensors and all the injectors and all that stuff for $500 being a 5.3, and if you try and source out the rest of the parts missing I know you're gonna spend more than $500.

Are you doing a CA smog legal swap? I don't think you can put a truck motor into a car.

Ok thanks thats what i really wanted to know if i would spend more to get the accessories and other things then what the engine would cost and as for smog this is mainly gonna be a track car once i do my lsx swap

LM7 can be bored to 5.7L, and pieced together cheaper than paying for a real LS1. I'd buy it. I don't know as I'd install it, or even rebuild it just yet, however.

Buy it, sell the heads for $200, use the rest to piece together a partial engine or keep as spares

I'd want to look the motor over before plunking down the cash... why is it missing 1 valve? I'd need that question answered to my satisfaction before I bought it. If it dropped that valve while the motor was running, don't waste your money.

Atilla the Fun

That's a good point, but how the heck is an LM7 gonna drop a valve? I'd say either manufacturing defect, or it got pulled for some other reason. We all saw that article in Car Craft where they fitted a well-used LM7 with the prototype Thumpr cam and a single plane, then twisted it to 6900 rpm with stock valves.

The guy said that he does not know the ast of motor so which is the reason he's selling it cheap so I I'm thinking it might just be a scam

The engine and trans are a good chunk of the money spent on these swaps, but i'm pretty sure the actual swap itself will be more than $500 unless of course you already have alot of the conversion parts.

SiCkRs

Well other than what the guy is including on the post i posted wouod i still have to put in about how muh more money for i could know around how much i would need to get a loan for.

It all depends on how in depth you wanna go with your swap as to how much it will cost. You'll need: Engine and transmission swap mounts, PCM tuning, exaust, a way to regulate fuel pressure, 255 lph fuel pump, LS1 wiring modifications - contact pocket for info on this, and i'm sure I'm forgetting some other important details. It's the little things in this swap that start to add up: radiator hoses, PS pressure hose, fuel lines & fittings, etc.

Does the engine come with the harness and computer? if not, that needs to be added in there too

Yes it includes the harness computer complete dash, fuel tank, radiator and fans too
