H/C or 383 stroker kit
H/C or 383 stroker kit Ok guys I want some advice as to what route to take. I gathered some funds which is enough to get either a stroker kit or trickflow h/c. As much as I want the h/c package, I'm a firm believer in more cubes which means more power. Also, I would like to have stronger internals for further future mods. I was leaning towards the stroker option. Use the money left over for p&p stock heads, get a custom cam, and intake. There are so many ways to get power but I'm trying to get the most out of the money. I like it to be streetable. 83,000 miles on the motor. I know the motor is still good but I would like to get more power and stronger internals for the future. Better to do it now than later. So any suggestions?

Sounds like you should build a complete 383 or even a 402 and then pull your current motor to drop in the new one. Save the old motor for the day you need it most or sell it to make some cash back. Good luck !
I was thinking of stroking my current motor. I was going to get the h/c for my LS1 but I want to stroke the motor and get stronger internals.

You should strongly consider Schwankee engines. Amazing prices, and great parts with very customizable upgrades. They are a sponsor here so you should give them a call. Sorry bro but after 16 hrs at work I am feeling too lazy to go dig up a link. LOL Later

Power is generally limited by heads. Going with 10% more displacement should increase your peak torque about that much, but it won't do much for your peak power because the heads will only move so much air. It will cost you a lot of money for what improvement you get.
Heads/cam/intake (HCI) can build more torque everywhere if you do it correctly. The stock LS shortblocks are very strong, as evidenced by many HCI packages living for a long time on stock shortblocks.
Certainly $2500+ heads, combined with a good manifold like the FAST 90/90 and the correct cam will be killer on a 346 or a 383.
For bang for the buck, however, you might consider swapping to 243 heads with just a really good valve job and a bit of work near the valve seat, some milling to raise compression a little, a FAST 90 or even an LS6 manifold (you can have it converted to 90 mm reasonably), and a really good cam and valvetrain using stock rockers and lifters all on your stock shortblock. The torque and power increases might truly surprise you. This has been done. Heck, GM added 55 fwhp to the LS1 C5 Vette engine with their version of what I just described. You can do quite a bit better.
IMO, you are power and money ahead with the lightly massaged 243's (Stage 0.5?) than you are having your stock heads ported.
If you don't do H/C/I with the stroker I think you will be disappointed with the outcome, and much poorer.
You asked for suggestions.
Good luck with whatever you choose to do.

Verdad Gallardo Those that gave me suggestions, I appreciate them. I still havent made up my mind yet. But, I'm kinda leaning towards the stroker option. I wish I can do h/c and stroker at the same time. Perhaps I can. I just gotta keep looking for some good deals.
I agree. In fact, I decided I will get my motor stroked and do h/c at the same time. A good friend of mine who does work on my car and owns a legit shop told me I should do this because it will save me money to do everything at once. That was his recommendation and he will do the work on my motor.

trick flow heads are the only way to go..but understand its a whole package that will maximize your hp....i am making 532/472 from my 383 and there is nothing i didnt add to the package to maximize the hp and still keep it a street car...
Definately listen to these guys on the heads cam prior to a short-block. The 383 won't do much for power without giving it the ability to breath with the extra cubes. We've done plenty of 500+rwhp 383s, but you might also consider the 408 iron blocks. The price is very similar to the 383 setups, but you get bigger bores/more cubes for very similar money. The extra torque from the cubes will definately make up for the extra weight from the iron-block.
Give us a call if you get time & we can help you put together a package that works for your budget.

Now that I decided to do h/c and the 383 stroker route, I'm having a hard time trying figure out what brand stroker kit to get. Lunati sells real good stroker kits but it's a bit pricey. I went to Texas Speed and I see they got some good deals. So, anyone can tell me about the stroker kits from Texas Speed? Also, what stroker kit upgrades should I get?
For the price of having your motor stroked out to 383 I would just get a 402 stroker from tsp and throw on a set of stock l92 or Ls3 heads and intake and call it good. If you have the chance to get a 4" bore then I would do it! I have a ls6 396 stroker and if I had to do it over again I would go with a different block with atleast a 4"bore. Just a whole lot more choices for heads and the price of l92 and ls3 heads are unbeatable.

Oh yeah! The stock ls3 heads will work great for now and you will still have room to grow down the line like porting and the new fast intake. Stock these heads flow like 320-330 cfm. It's the best bang for your buck when it comes to strokers unless you want to go 6.0 iron block. Personally I would rather spend the extra few hundred dollars for the 60-70 pound weight reduction of the aluminum block. The ls3 heads can be bought for under $1000 fully assembled and like I said still have room to grow. I would eventually get them ported by Total Engine Airflow. With your cores it's like $800 for 30 more cfm. That's equal to 30 more rwhp over what you would already have. Just give tsp a call they can set you up a nice deal on that shortblock. Heck they could probably set you up a long block with everything you need ready to drop in. A little hint to save a few buck would be to ask them about paying with a cashiers check instead of debit or credit card. This saves you 3% since they don't have to be charged to use the credit card machine. That's $30 per every thousand. Also have them ship to a buisness like the place you are planning to have install it. This saves about 20-30 on shipping.

You have an ls1 ... 3.900 bore. To go 383 it will be honed .005 and then a 4" stroke crankshaft will be employed.
The 402 is a 4.000 bore with the 4" stroke or as we build them a 403 with the .005 hone to a 4.005 bore.
Ok i thought the 402s for LS2. Thanks for clearing the air.
