Ok it time to pull the motor out of my 92 Z28 and i don't want to go back to the stock motor. So what should i go with i have a 350 that is 30'over that i can build or should i just go with a 383. i have been reading about guys putting a LT1 or a LS2 motor in give me the pros and cons to this.

 

350 - Pros: One of the most popular performance V8s in history. Great aftermarket support. With simple/smart factory and/or aftermarket parts choices, better than any 305 in existence.
Cons: For a relatively few more bucks, you can have a 383.

383 - Pros: As close to a bolt-in in a V8 3rd gen as a high-performance engine can be.
Cons: It's still a Gen I SBC.

LT1 - Pros: A pretty good improvement over the Gen I SBC. Sequential port fuel injection. Decent aftermarket support. The block is externally basically the same as a Gen I SBC as far as bolting it in goes, but you'll be modifying fuel and wiring systems to get it to run. Gen I/3rd gen performance exhaust works with it. 3rd gen transmissions can be made to work with it.
Cons: Limited production run. Only used in passenger cars.

LS family - The full list of cons:
- It needs adapting to fit in your chassis
- 3rd gen transmissions can be made to work, but the LS family is the better choice for several reasons, increasing the swap expense
- Fuel and wiring mods similar to LT1 in extent and expense
- Exhaust will be expensive
- Aftermarket performance upgrade choices available may make your brain spin in your skull
- You won't be able to wipe the smile off your face after you drive it the first time

 

350 is good but like stated above 383 is cheap to obtain

383 would be easy route with a miniram ,super ram or a carb

LT1 is good but I wouldn't mess with it not worth it ...but can make good power .. But it's Optispark is a huge weakness

LSx it is involved project and it adds $$$ but some things are worth the extra hassle you won't regret it
