I'm looking at building a 395stroker, is it a waste of money also what would be a good combo? I'm really doing it to be different be able walk bolt on cars of cores I want be able push 400+ rwhp. Thanks hope you guys can help me out.

Really, 400 hp is not that hard to do with stock cubes. That said, a LS1 stroked to 395 requires a 4.125" stroke. It would be better to limit the stroke to 4.00" for 383 CID.

With the stroke over 4" the piston skirt starts coming farther down out of the hole causing more rock and premature wear, that is why most people go with a 4" crank and not the 4.125" throw

What mark said, plus the long stroke pistons have the ring landings closer together due to the pin placement which means the piston crown is thinner and weaker.

so a 383 would be a lot better to build?

If you are set on building your LS1, then yes on the 383, that's my opinion.

Get an iron 6.0 block, build a 408. Enjoy!

^^agreed.
i myself prefer to be blown than stroked.

This is what I did... If you are on a tighter budget buy the best parts you can for the bottom end and bolt your stock heads/intake back on the stroker.....then when you can afford heads/ intake swap them out....just don't go cheap on the bottom end.

I'm running a fully forged bottom end with H-beam rods, flat top pistons -4cc valve relief, 255/263 .624/.624 115lsa, Edelbrock proflo xt intake and still running my original 241 heads, ported and milled and my 408 pulls hard as hell to 8,000rpms

Do you think displacement is the key to power?
If so you are mistaken, the topend makes power, the bottomend supports them. More displacement can support a bigger topend but adding displacement without improving the performance of the topend is a recipe for an expensive failure.

Far as topend work porting stock heads can be a great, I am saying you can't leave the heads as cast and expect huge gains.

What I was thinking was doing ls6heads with edelbrock victor intake I'm not to sure about the build up of the valve train or cam yet. want build it up but be streetable at same time.

Another question is what would be good heads I notice that the 383 that tsp has for sale has 5.3 heads are those better for a stroker? http://www.texas-speed.com/p-119-tsp...ong-block.aspx Or should I just order a short block from tsp like there 408 or the 421?

For a street motor, I would not get the Edelbrock Victor intake. That's mainly for racing and high rpm. Low end torque would suffer and you might have hood clearance issues.

The TPS 5.3 heads are a good bang for the buck, but for a few bucks more, the LS6 heads are better. On the long block link, you have various drop down boxes with different options. The 5.3 heads are just the cheaper option.

With the LQ9 block, again you want to stay with the 4.00" stroke for 408 CID. The 421 option uses the 4.125" crank which was already discussed why it's not as desireable.

alright that helps out a lot. thanks would a good set up would just take my ls6 intake port it out get ls6heads with a 383stroker kit be a good set up? looking at staying n/a street hotrod what be a good cam?

whats diff between ls2 and ls6? i herd pple using ls2 cause there almost the same

Just to be clear you are looking at porting the LS6 heads too right, not just the intake?

outlaw-53

yes the heads also

LS6 intake, LS6 heads, and a 383 stroker would be a great combo. As for what cam, that's a subjective topic. For good driveability and to reach your 400 hp goal, it can be fairly small. The stroker can take a little bigger cam than a stock cube motor. Are you looking for a smooth idle or some lope? What kind of vehicle is this going in and how much does it weigh?

LS2 vs. LS6? Do you mean heads? If so, they are the same exact casting and flow the same. True LS6 heads have sodium filled lighter valves. It's not a big deal unless you want to run really high rpm.

I want a little bit of lope I got a set of true duels sitting in my garage until next year when I get my motor all built and dropped in. its a everyday driver in the summer type of car so nothing that kills me to bad on mpg i do have a gas saver car for long hauls but I love to drive my camaro everywhere all the time so im looking for a great strong running 383 that can eat up alot of things but wont kill on mpg. i do love the lope sound. If i can get about 18mpg i be happy no less then 16mpg.

ya i men't heads. thanks for the info thats what I was wondering.

The ls6 intake is going to quickly choke any 383 with even a small cam. Porting the ls6 intake is pointless and a waste of money.

Also, looking for 400 rwhp and gas mileage out of a 383 is a waste of money. You can easily get 400 rwhp out of a stock ls1 with a medium sized cam and a set of stock, ported heads.

so many choices keep popping up lol Iwant get a set plan to build a motor this summer and drop in by winter and tune all the other goodies
