What enging do you want in your truck?

[kalirodding]

I have an LT1 out of a 96 Impala SS thats going in my 55.

[creamsicle68]

i voted other. because like others said. ide go the cummins route. cuz backed with a 6spd trans you can get a cummins to bark like no other deisel ive ever heard. the cummins is 2nd behind the v12 detroits in coolest soundin deisels in my book. but a detroit wont fit it a c10 too well haha

[phx 4x4]

have always wanted a 383 stroker motor

[Kim57]

I agree the 348 is a sweet looking engine.
If I had buckets of money I would get me a 409 and stick it my truck.

I have a mdly built 350 pushing 425 on the HP and 450 on the torque. I know, 350, the most over done, common motor but it's bullet proof and with the 3x2 intake it looks pretty good.

that motor must have been out or built for a street rod 3x2 and long block hugger headers are a true sign

Actually I had the engine built for me and didn't want to go with a plain Jane 4 barrel so I dropped a 3x2 on it just to add some retro vibe to it. The headers are hedmans but they are designed for a 55-59 that's using the original steering column so I've since removed them and have a different set on there now. The headers from the picture are collecting dust in the back of the garage, still wish I can use them but it would force me to run the steering shaft between the block and the headers, not a good thing in my opinion.

[Kabwe]

I'm currently building a 383 Stroker for mine. I have a 5.3 with a 4L60E trans that I will not use for this project.

[hotrodsbyray]

I always thought an inline Chevy 6 with bore / stroke, Wayne heads, headers, Weber carbs on custom intake.

But, if I had one right now I would put a 308 Hudson with Twin-H power no matter how much firewall "finessing" I would have to do.

i want an ls7 sooo badd

dont waste your money. get a ls1 short block and build your own. much cheaper

[joeys66pickup]

i think a properly built 6.0 would make a ls7 seem pretty slow(ok not that slow but still)

What colour is the sky on your planet. Here on earth it's blue.

[Hottrucks]

can someone give me a short list on these LSX engines..like what they came in......and would my old headers fit...I'm sure the intake wouldn't but what about the edlebrock carb I have.....I would love more power and could do the EFI and harness but a carb would be bolt and go..

I would like to know that as well.

[Hottrucks]

quick research says crate motor?? I don't see many crate motors at the u pull it??...

I think the 5.3 looks to be the new cheap up grade with the 6.0 being second

check out this link for motor sizes and what they came in very good info

These engines are awsome. They have 6 bolt mains & the heads flow very well from the factory. I drive my 9 second camaro for real. I drive it to work, take road trips across the coutry etc. The engine has not broken yet. Now the transmission has blown 4 times but I think the new one is going to hole (hopefully)

Simply put, the true LSx engine is an aluminum block
The iron blocks are truck engines, but just as capable. Weight difference is only 65lbs
Truck engines short blocks are esentially the same with small differences like:
~Serpentine system (vette's accy's closest, then F-body's, then Trucks stick out far)
~Intake manifolds (trucks' tallest)
~Exhaust manifolds (each application is different, TONS of them out there)
~Sensors. (several differences. With the right harness, and PCM, makes the swap job simple




The engines come in sizes:
4.8L
5.3L
5.7L
6.0L
6.2L (cadillac only)
Vortec 4800, 5300, 5700, 6000, 6200

There are a few Front wheel drive vehicles with LSx engines, but they don't swap easy, and the block castings are different.
Such as:
Impala, Monte Carlo, Buick Lacrosse, and the Grand Prix


Truck motors come in aluminum as well, note L33, L92, L76 amoung a few.

LSx is generic for Gen III/IV motors. So fake LSx is a misnomer. Vortec is much better term for the truck motors.

*Basically the same as an LS1 but with better heads (243 head castings) a more aggressive cam, and LS6 intake manifold make up the power differences.

TRUCK ENGINES - STILL GENERATION III
The truck engines are very much like the LS1/LS6 and are still classified as a Gen III engine. They are mainly iron with the exception of the LM4/L33, and as a result weigh approximately 80+ lbs. more. All the parts from the LS series can bolt on to these engines and is recommended for any swap as the accessories and intake manifold usually fit better from an F-body. The 4.8 and 5.3 can both be punched out to a 5.7 (346 Cubic Inches) simply with a bigger bore (the 5.3) or a bigger bore and the 5.3 crank (in the 4.8's case).

GENERATION IV - Generation IV engines are very similar to Gen III and most parts can be interchanged. The Gen IV was produced with displacement on demand and variable valve timing in mind. Not all have these features, but they are available. Also they have a 58x crank trigger, front cam sensor, and side mounted Knock sensors.

LSX is the only way to go, lol. Whether it's a 5.3, 5.7, or 6.0,. They have plenty of power, reliability, decently cheap, and tons of aftermarket parts available.

[Kid]

LSX, no brainer. I went the economical route, 5.3 truck motor for my ride, but the sky 's the limit with the LSX family. I'll never go back to a carbed engine

i still would like a Carb on my LS... just seems to fit the bill for all motors to me,
good ol holley or something and Boom run it to the ground

[nickp51chevy]

There is a lot of really good information on this thread. Let's keep it up.

[mylow53]

i prefer the extra hp from a stroker 383. pleanty of hp and tons of touque. not to mention parts galore...

You got that right. If I were to have the engine of my dreams it would be a 454 small block but we are talking big cash and it would be in my 55 Sedan.lol We are talking 12 thousand.lol But that is a dream engine I will never own. I'll stick with the 383 stroker.

[Bigblue29]

I like the 235 swap. They are cheap and look very similar to the original straight 6, but then again. If I was going to update everything else I would go with an LSX motor!

[joeys66pickup]

kinda greenish... but other then that why wouldnt it? i know a 7' has the extra cubes but the ones i have seen built up dont impress me as much as i thought they would(stock yes they are still amazing) but the 6.0 in a pink 99' camaro that terrorizes the track i call where i home is unlike anything i have seen big block small block turbo nitrous whatever; its like the damn thing is possessed and doesnt know the meaning "quit pulling"
