Strokers

**tep98ws6** · 09-24-2009, 08:25 AM

I've seen a few folks on them that have them... I'm doing a stroker for my TA as my machining project in class and I'm having a hard time finding pros vs cons of a stroker, any issues with swapping heads on a stroker, ect.
Just curious as to how normal stroker drivers feel about them!

UGH. Posted in wrong thread again. Sorry. I need to get my eyeballs examined.

Strokers are going to give you more cubic inch (more air to breath) but in some cases have put too much stress on the wrist pins and cause early failure. I've got less than 3k miles on my stroker motor and no wrist pin issue so in my experience...getting stroked has been great.

Oh...and on the heads....I went with GM cast 317 heads from a LQ9 motor. They have bigger combustion chambers which is more suited for forced induction. I probably should've went with a set of AFR heads because aftermarket (not factory cast) heads can be machined for more flow than a cast set of heads.

383 is what i'm aiming for ... i'm going to get a separate bare block in case something catastrophic happens so i have my stock engine still ... i just want to build something badass for good $$ with the chance to say IIIIII built, stroked and installed it. with the heads, i was curious as to if you go with bigger heads on the block and it being stroked, do you lose any power made? i know sometimes if you go a little too big, you lose -- i don't know how to type it out but i don't want that. i want every cubic inch of power i can get without any unnecessary losses

thank you !

Getting the right heads and cam combination is ALWAYS key to any motor build. Well, with forced induction being the only exception to that rule. Talk with a good machine shop that knows LS motors inside and out and have them figure out what cam to match the head configuration and motor air flow.

You must have alot of money to build a whole other motor from scratch.

That's an awesome concept but you'll have to get fuel rails, injectors, etc all new to build a second motor. But hey, if you can do it.....that's perfect.

Best of luck on your build. Take lots of pics and share with us.

no no no, not lots of $$, lots of hook ups (ex: school's discount for parts is 60%), doing the labor myself, transfer of externals, ectect

i'll take pics once i start ... i heard from various people that strokers sound weird ... i've never really noticed anything, but have you ever noticed anything weird sounding about them?

There's no difference in sound....that's a weird comment. I have kooks stepped long tubes, kooks catted y-pipe and borla cat back. Sounds like demons from hell have been summoned when I put the pedal to the metal. muwhahahahahaha

You'll have to tell us what everything costs...I'd be curious to know. For me...I don't like to look at how much my setup cost. I think I'd have a heart attack if I really know.

niiice. mines just stock y-pipe, flowmaster cat back and cut out. it's loud as hell but i want it louder. i love loud.

oh im gonna keep a log of everything. you should see it now for just repair work i've done since i bought it

but ALL repairs should be fixed by monday, body work has been done, she's perfect, now time for fun

Well the cut-outs should do the trick as far as being loud. Mines bad enough when going down the freeway. Can't hear anything else.

You're supposed to do the motor, trans and drive train first...then the body work. But I'll cut you some slack on this.

Couldn't you have just welded in a bar for a door til you get all the motor stuff done?????

**tep98ws6** · 09-24-2009, 10:23 AM

i could have done that or put one of those super cool truck bed nets over the door

See, now you're thinking. Remember the car has to get ugly before it can be beautiful.

oh it'll get ugly. but i still needed to get inside the car to drive it!

when i'm doing the swap, i'm going to have my hood, front clip, fenders & engine bay repainted to get rid of all the rock chips
working & going to school at an automotive school has it's perks

Perks are good but how's the pay?

That's good you can get all that done while the motor is out. That thing will be looking real sharp when you're done.

ehhhh better than the franchised shop i used to work in, that's for damn sure! i hope so. it looks 10x better than when i got it in june already. it should be decent until i start doing the build after i do the fuel pump on monday... if not

Did you get a racetronix fuel pump system?

Glad you're really taking your time and putting good quality into your ride. I'm sure the guy will love you for all you're doing for it.

heck yes i did! i want it to be a bad bird

the guy will love me? what guy? haha it's going in my car!

Wow, talk about a freudian slip, I meant car. haha I'm busy at work and I guess not paying too much attention to what I'm posting. I have no explanation why I wrote guy instead of car. Please accept my apologies.

The racetronix system is the best deal IMO. If you're running a high performance motor that needs alot of fuel delivery...that system does the job beautifully. I ended upgrading to the twin pump setup from Lonnies Performance. That has two racetronix pumps in it. My old one I sold to a friend that uses nitrous....and no problems with fuel on that car either.

Then go to 402/408 with either an LS2 (402-404) or LQ9 (402-414) block.

As for the heads, this is what feeds the motor, and you will want a well matched set of heads for the cubes AND for the cam.
I am running a 248/254 629/622 113 cam and Patriot stage III LS6 heads.
I would LOVE to get some AFR 225's (ported) on there....more for the powerband than anything else.

Agreed with the Racetronix stuff. I am running the single in-tank 255 kit. Not a problem with it for 4 years now.
