Stroker question.
I'd just pick up a 370 short block. With the larger bore, you will pick up more power than the 383 and still get you decent gas mileage. Not only that but your ls6 intake and ported stock heads with matching cam will feel more at home on the 370. Still not optimal, but better than on a 383.
6.0 228 cam bolt ons and fast 90+ intake will be cheaper than the 383 kit alone much less the machine work.... You can pick the 6.0 blocks up fairly cheap, sell your ls6 intake and your old motor to recap some of the costs. You can do this for a lot less than the 383 and i bet you make your 400hp...
Someone earlier said 400hp is a pretty easy number with your LS1 fast intake and cam alone.
6.0 running $1000.00
228+ cam pkg $700.00
Fast 90+ combo $1100.00
Sell your ls1 (if its running) -$1000.00
Sell your LS6 intake -$300.00
Total 1500.00 in parts vs. how much for the stroker kit alone?
Yes I know the numbers can be changed as you can actually find a 6.0 for less than 1000.00 and the other items as well but those are safe numbers from what I have seen.
With bolt ons and tune 400 should be pretty much in the bag and good drivability.

so a 370 would be a lot better for what I want to do is what you guys are saying? ditch the ls1 and stroker idea. but the 383 be same as a 370 if i still wanted go that rout just because my ls1 only has 24,000miles that I got out of a donor car for my ls swap into my v6 camaro.

well i think i rather keep my ls1 has low millage and just spend extra money and just build a 383. I'm sticking with that now. so far lets get this straight I'm going do ported ls6 heads use my stock ls6 intake for now I plan on a fast intake once I get some money down the road. 383stroker kit from tsp cause not a bad price. now I need know what type of heads I should get flat top or dish? also what be a good cam? also injectors.
Flattop pistons would be my choice for N/A (actually 3cc or 4cc valve relief). For a cam, I'd probably get something like the Torquer v2 or if you want something a bit milder maybe the 228R. Injectors? It's hard to beat the tried and tried green top Ford 42# injectors. They're easy to tune and are very common. Plus you'll have some extra margin to add more mods down the road. That's what I'm running.
always go for the largest engine you can afford to build for the street! a 395 isn't a waste of time but a 402-408 is better than both but not by a whole lot! the 383 is a Great combo that lasts a long time built correctly
I recomend the Wiseco -8cc dish piston as it will allow you to use just about any head out there and stay at or below 11.5:1 compression for pump gas with a 383
If you can afford it Use an LS2 Aluminum block with a 4.00 stroke crank to make a 402
383's and 395's are awesome but when you start really pushing the envelope that Tiny bore size really starts limiting flow into the engine
The Most Effeciant Style of engine for Power, RPM, Torque is achieving your cubes Using the biggest bore size possible Because Its Mechanically more effeciant and The Cylinder Heads Have a Bigger hole to dump air and fuel into
The 5.7's aka 346 are a much bigger waste of time and money imho and its usually guys that don't own 383 or bigger engines that like them
I'll tell you what take a 346 making 525rwhp and a 383 making 500rwhp and 95% of people would take the 383! JMHO
I'd like to see you build a 11.3:1 383 with Advanced Induction CNC Ported 243 226cc heads, a Nice 228-236 hyd roller, FAST 102/102 LG Headers ! I think that would be a heck of a street engine

I have a LS1 in the GTO and dynoed 430 hp through a 3200 rpm converter with an A4 trans (stalled autos tend to dyno low). A M6 would probably put down 450-460 hp.

I think when I go order my heads im going just order tsp cam head combo. like you said badbat the torq v2 cam with ls6 heads and just use the stock ls6 intake until i got some cash for a fast intake. of cores the tsp 383stroker kit with flat top pistons -3. you guys think its okay if i use the ls1 stock 1.7 rockers or go 1.8? hows that sound to you guys?

Stay with the stock 1.7 rockers, maybe get the trunion upgrade if they have some miles on them. Don't forget to pick up the Texas Speed basic cam and heads swap bolt and gasket kit too.

Thank you guys and batboy you've been the hugest help on this websit that I've ever had. Thanks for the stall Help A lot of cars I built where old school bigblocks. That helps a lot Thanks guys if i have anymore questions ill ask you guys.
I guess everyone has an opinion. I agree porting a LS6 intake manifold is not a good investment, but I disagree that it will choke a 383. Why would it choke a 383 and not a 370? That makes no sense. It is true the LS6 intake will not perform at high rpm like a FAST will. I get you like larger bore and smaller stroke engines, but there would be very little performance difference between the two. In fact, the 383 would probably have a bit more torque. I'm assuming you are talking a iron block 370 which would be heavier than the LS1 block. Where the iron 370 combo really shines is with forced induction.
the over square 370 will make the same, if not more power than the 383, but less torque. I agree, but with the shorter stroke of the 370 it will be more reliable as well.
Yes, the iron bastard...not 80 more pounds...lets scrap them all! Yes, they do shine under boost, but the fact that there is multiple rebuilds in the iron block and more strength is worth the 80lbs to me. besides, 80 lbs is not hard to shed from these cars.
