stroker kit

**01tao6gto** · 10-18-2007, 04:23 PM

I own a 01 trans am and i am considering putting a strocker kit in it but i heard you could only bore an ls1 block .010 without sleeveing it, curious if this is true and what other problems i could run in to?

i dunno what the specs are on how much you can go..

but if u are in there with the engine out...u might as well go with more than ten...make the time worth it..

A stroker kit won't require a bore. Just a hone.

Stroke a stock bored LS1 to 4.00" and you get a 381.88 cubic inch motor.

I believe a 383 is as large as you can go with a stock block.

396
3.903 bore and 4.125 stroke

how do you "Stroke" a motor? Is this expensive? Should only a shop do this? Whats the process? I would LOVE to increase my cu in

get a bigger crankshaft and/or bore your cylinders out (in simple terms, make your cylinder diameters wider and have a longer crank to increase displacement, but you dont have to do both)

yes its expensive. couple grand for real kits. i would only have a shop do it cuz u have to machine the block for the extra length of the crankshaft and you have to bore the cylinders perfectly without screwin it up. one little slip up and you need a new block

its an expensive project, but causes massive increase of hp

someone correct me if im wrong on any of that

$10K will get you a longblock 402/408.

And I don't like going with a 4.125" stroke on a stock bore LS1. Piston rock can become an issue because of how far it moves.

ten grand is way more than enough

**01tao6gto** · 10-23-2007, 04:26 PM

ten grand as in .010 of a inch off my block! because i heard you could only take ten off and the ware on an engine with 90,000 miles might be more?

**Mr. Luos** · 10-23-2007, 04:57 PM

I can't imagine you would need to take more than that off unless you tossed a rod or had something stuck in a cylinder.

Yeah, I've heard only honeing an LS1.. not smart to bore it.. the LS6 block is a little better.. but still not recommended.. one of these days I need to run my numbers to see which block I have.

Luos, we need to match up your car with my camaro.. would be a good race!

**Mr. Luos** · 10-23-2007, 05:24 PM

Might be close.

I promise I will start in 2nd and skip 3rd and 4th.

I didn't run it, but those are actual ET's for the car. I had a friend give it a try because he wanted the experience of running a car down the 1/4.
I think. I know the 17.2 is legit, not 100% about the trap speed.
Found the slip.

I guess they run 15.5-15.6 stock at sea level.

Well.. mine has exhaust leaks up the ass.. (lol) the idle is still off, and it wouldn't shift into 3rd... even with lifting... so I was clearing the 1/4 in 2nd!
