I have been trying to decide for a while noe to go with a fully assembled ls2 stroker motor or go with my H/c Ls1 setup. I could get the ls2 stroker from TSP for around 8g. I currently have the TSP PRC 2.5 5.3l heads and the Ms3 cam right now. I haven't installled them yet and im trying to decide whether to go with my original plan or go with the stroker. My ls1 has about 80k miles on it right now but i want to get some good numbers put to the ground. I averaged it up and ill be spending right around 6g for all the parts i want for my Ls1 block. This car will have to be streetable and it is a m6. Any advice on which motor i should go with?

What are your other mods? ide get a rear if you dont already have one. Ide also get the TSP forged 383 shortblock and you could spray a 200 shot with addition of a fuel pump.

I really dont want to go with any spray. I want it to be all motor.

go with the 414 if you have the rear, go with the ls1 and buy a rear if not

how about some more detail, what do you currently have done to the vehicle, are you already setup to run a bigger cuber inch motor? is the suspension built to handle big torque? are you looking for some fast time slips or just a nasty street car?

I mainly want a nasty street car with a lot of torque. All i have right now is the Heads, Cam, Kooks Headers, Fast 90/90 setup. I am about to purchase a clutch and a 9' rear hopefully. I just don't know if i am going to be satisified with the torque numbers with the Ls1 motor. I will be doing the strano/koni suspension setup for christmas hopefully also. I won't be going to the track much, just street racing a bit.

Remember, there is no replacement for displacement. Boost is really close

in that case i would go with the 414 or the 383 short block with a procharger

TSP says that you can't use the Fast 90/90 with the L92 heads setup. Any ideas why anyone? They say you have to use a different setup

don't buy the longblock. Get the shortblock and put your stage 2.5 heads on it.

If i did just buy the shortblock, what other parts would i need to get? Could i transfer all my ls1 parts to the new motor or would i have to go all new parts? Would buying the shrtblock save me money in the end? I just dont know what cid motor i want to go with. 414?408?402?

Mike@HSW

depends on your budget, the 408 is cheaper so you can always go that way. or if you want to save some weight and go with the 414 then i would do that, its only a hundred bucks more then the 402 so why not. Your heads, headers and intake will work with it. Sure some better heads, and bigger headers would work better, but you should be ok. It would only rob you of top end power

There are so many options out there. Someone earlier pmed me and reccomended a D1SC procharger setup instead. Sounds like a good deal, just not sure what im going to do.

supercharging is definitly an option but it is expensive. but then your putting a decent amount of boost to a stock bottom end and run the risk of breaking something. I have seen a stock bottom end take up to 18 lbs of boost, but its not a good idea and no one can give you an exact amount before it will break a rod bolt.

I think if i keep it at a low boost level ill be fine..
