Need some help on an engine build
 

I want to build an engine, but i cant decide and building from a LS2 block, or LQ4/9 block. Im not looking to spend a million $$ on this project either. With money being a key factor, im also not trying to be a cheap ass. I want to up the stroke in the engine block of course, but will i have to have the block bored? or can i not have it bored and have it be a 402? I want more power, and i dont feel like re sleeving my ls1 or going FI. Its not going to be a 100% track car, around 20% daily driver, 50% street racing, and 30% track. What are some of you alls opinions?

An LS1 block can only be made into a 383 as a general rule of thumb. An LS2 can be made into a 402 as a general rule of thumb. Expensive resleeving and stroker crank larger than a 4.0 are out there, but we don't use them.

Take a look at this build where we used a new LS2 block and installed good non trick parts.

Here is a build where we kept the stock LS1/347 crank and added better rods and pistons, etc. http://www.exoticperformanceplus.com...Car.php?car=54 Bob

If you buy a new LS2 or 6.0 iron block, then you don't need to bore it (402 with a stroker kit). A used block will probably require boring unless it has super low pampered miles.

Here are some examples of what Texas Speed has to offer to give you an idea of components and prices.

Even with a new block, we use torque plates and hone it. We want the bore to be perfectly round when the heads are installed, to optimize piston ring sealing. Bob

Yep, that goes without saying, you should always hone the cylinders to allow your rings to seat properly (new or used block).

how much money do you have to spend and how much power do you want? if money is a big factor forget stroking a ls2 and put a nice set of p&p heads, cam, and intake on your ls1 with a 150 shot of nitrous and save a ton. if you have the money go with a ls2.
