im going to buy a shortblock 408 stroker for my engine build this winter. i am just wondering if the whole rotating assembly is going to come preassembled and already installed in the block without having to do any measuring and balancing or anything. basically will i be able to just pop in the cam and heads and everything else on the top end and outside and be ready to roll. or is there gonna be alot of extra crap that needs to be done still. and what all exactly comes with the shortblock other than the block, pistons, rods and crank?

 

That is it: just the crank, rods and pistons balanced and assmbled in the block.

 

 

im assuming things like bearings and freeze plugs and those type of things will be include as well or am i wrong?

 

correct

 

Best route to go rather than trying to do it yourself. Texas Speed has an excellent selection of short blocks.

I bought my shortblock from TSP and they installed the cam and timing chain for me. I just had to install the windage tray, oil pan, oil pump and everything from the heads up.

I want the 408 ci but it says 402/408. what makes it the 408 rather than the 402? do i have to choose the upgraded piston bore sizes in order to achieve 408 ci?

 

with a different crank it will make it a 408 if im not mistaken?

either that or they are referring to the ls2/lq9 with the different ci

 

A 402 is an LS2 that has a 4" crank in it. A 408 is an LQ9 bored to 4.030 with a 4" stroke crank.

We offer a 403 instead of 402. This is done by cleaning up the bore .005. We do this in order to ensure the cylinder is uniformity.

The LQ9 408 will accept all your Ls1 stuff where the LS2 403 will need a conversion kit.
You'[ll make more power with the 408 but the 403 is aluminum and some don't want the added 75#'s of the iron block LQ9.

We offer short block as well as long blocks and complete "crate" style engines as well at competative prices. I can work up a few different quotes for you and show you the differences.

 

LQ4, LQ9, LS2 can all be 402 since it takes a 4.00" bore and a 4.00" crank on a V8 to make 402 ci. Bore the 4.00" block 0.030" over and it becomes a 408, regardless of LS2, LQ4, LQ9, or SBC, SBF.

 

so basically in the link i posted what parts would i have to select in order to get the 408 instead of 402? or would i just have to give them a call when i order it and tell em i want the 408?

 

The stroker kit makes both, it depends on if your block is new or used. If it is new, then leave the bore at 4.00" stock and it will be a 402. If it is a used block, having it inpsected will determine if it needs to be hone or bored. Then you will have any where from a 403 to a 409. I am not a fan of boring a block just for the heck of it. If you want a 408, then just tell them that. The parts combo will not decide that, the bore will.

 

For conventional sake and what 98% of the people here talk about the 402/403 is and LS2 and the LQ9 is a 408. This is what we deal with 98% of the time. (plus he was looking at a LQ9 408 so I was addressing it as such)

Yes you are correct any combination of cid is possible depending on how much you over bore the cylinder. Didn't think we needed to cover every single combination possible since most people want the biggest they can for their buck. We dont see to many requests for an LQ9 403, most people want the xtra cubes to make the 408.

You also forgot the LSX block which can make a number of different combinations, but again most people wont spend more money on a block and keep the cubic inches smaller. Its called bang for the buck.

Also we dont bore it for the heck of it. Its is trued it up to make sure we have a uniform cylinder to work with. Factory tolerances aren't as stringent. We take no chances.
