Planned on buying a Lt1 out of a wrecked chevy... but it sold.

Will a Block from a buick roadmaster work in my firebird? Will it have the perform the same if i put my aluminum Firebird heads on it with my stock cam or LE Custom grind?

My plan is to buy the roadmaster engine, swap all accessories from my current motor (including Heads, cam, and intake, water pump, alternator, etc..)

Will it work? What are the differences in the Roadmaster engine and the camaro/firebird engine?

only differences i can think of off the top of my head are... iron heads, water pump, oil cooler.... pump will work fine if u delete the oil cooler which is what im doing anyways.

So what all would i have to do to make it work?

PCM will work right?

T56 Bellhousing will work right?

Wiring harness?

Anything else i should know?

You could save yourself alot of headache by just buying a block from an fbody. You will need the wiring harness and different coolant hoses for sure.

Are you sure he needs the wiring harness?

Besides the heads, I thought it was a fairly straight forward install. Havnt done it but wait for more people to chime in.

There are roadmasters that have been t56 swapped so I dont see why it wouldnt work. Buying a fybody motor would be easier though.

There aren't any differences between the Roadmaster and the F-body LT1 block.

^^ What he says, PCM is the same also..so is a caprice PCM, both can be used in F bodies

damn

Too much trouble considering you can get yours rebuilt for around 2k bucks. Dont waste your time trying to make it work when it was never ment to go into a Camaro in the first place just rebuild your engine or find one that came from the same year as your car and save yourself the headache.

What do you think is in your camaro or transam dude.. So much mis info in here.. the Shortblock is exactly the same.. use an fbody waterpump, yes your t56 will bolt up, delete the oil cooler.. Only thing to make sure is that you use the proper knock sensors for the year car you have.. or pcm you have

he is right. use the old water pump from your fbody lt1 along with any other parts you may have from your fbody lt1. should be a breeze. what happened to your motor? im putting a b-body lt1 in my camaro but it was originally a v6. pm me if you need any info. lots of noobs on here dont know wtf they are talking about.

The short block is the exact same. Everything will swap right over. Short blocks can be had in great shape for 500 bucks or less. Add gaskets and time and it hell of a lot less expensive than a 2k rebuild.

^^ This.

The real question is what year is your car? B bodies carried a dowel pin-drive opti from 94 & up. If you have a 93-94 F body, you'll need to be prepared to accomodate the different opti style (i.e. if you have a 94 with a brand new spline drive opti, you can't use it and may be looking to buy an opti again). Your F body harness should work fine, tune shouldn't need to be changed if you're moving everything over from the top end. Can't remember the difference in the oil pan, but you can use your original, of course. Pay attention to the part #s on the knock sensors as well.

just some advice, MAKE SURE that that lt1 is in fact an lt1 and not an l99 (baby lt1)."5.7" should be cast around where the oil pressure sensor is (on top, in the back, on the drivers side)

you dont mean the L98, you mean the L99

I am in the process of getting a motor changed over from a 1994 roadmaster and putting it in a 1994 firebird. All the books say it will not work but of course it will by changing all i have seen on the post plus the crankshaft sensor and bracket. They are not the same as the roadmaster. I has a guy doing this but he said he had a motor like mine but it was out of roadmaster so now i am in a lawsuit bc the hp is not the same and he also broke my manifold bolts and motor runs like crap. Not sure why that is unless something to do with wiring harness. Tranny also started slipping and don't know why that is either. Maybe if anyone has helpful hints let me know. I got a hint, stay away from Settlemires in corinth ms

mine is from one, they are same, other than heads and cast iron, hub is different though so keep your old engine to swap out those parts and accesories. it has a bit more torque though than fbody
