swap a 350 tpi to a lt1 engine. worth it?
Hi.
It are probably a lot of threads of this topics but i jsut wonder what the biggest difference is between lt1 and 350 tpi? is it worth the time and money for maybe the little extra hp? or should i get new heads,headers ect to the 350 tpi instead?

Engine: LS1/LQ4
Transmission: 4L60E/4L80E
Axle/Gears: 12B-3.73/9"-3.89
Differences:
LT1 has better heads, cam, induction system.
The "worth it" question is dependent upon several things, such as how you use the car, the condition of the TPI engine, whether you can do the swap yourself or would have to have a shop do it, your budget, etc.

When I did the swap I used a corvette LT1 NOT a camaro or impala LT1 because the ac bracket will hit the bottom of the engine cross member. this will prevent the engine to sit right, or you can remove the AC from the engine.

if you were going to use the original k member then the corvette lt1 would be the one to get, but since you are using a different k member then i guess it dont matter what engine you get.. I am not familiar with that k member.

when you say induction system what do you mean exactly? Intake manifold, throttle body, heads?

No LT1 and tpi intake are different, tpi has distributor in back of the engine thru the intake. LT1 has distributor on front of engine underneath the water pump.

You CAN swap on an LT1 intake, but you will need to have it modified for the distributor, its been done many times before. Cooling mods need to be done as well.
You can also run the f-body setup and retain a/c. You will need to use a normal sbc passenger side motor mount and mod it slightly. See Firebat if you need hoses made.

LT1's have more HP potential dollar for dollar than the TPI engines. TPI engines are better suited for people who enjoy torque and driveability whose driving style doesnt have them spinning lots of rpm. LT1's have better cooling systems and charging systems, and require less money for performance parts since they have better parts from the factory.
LT1's are more of a 'bolt in' than LS1's but have less potential as well. I prefer the LTx when money and difficulty are a factor. But hey, LSx engines are cool too. Pick your poison!
BTW you can use the LTx f-body engine and accessories, but you need custom hoses and either knock in the crossmember with a torch or do as I did and notch it and weld in a recess to clear the compressor. Gives it a more professional look to me.
I love 'em all. They all have their own place depending on your goals if you ask me. Im doing an LTx next with a tpi intake ( yes thats correct)
