With all the new developments, i would just use an ls2 derived block or build a 408. the bigger cubes are hard to pass on by the price alone. but i do believe i would go through www.keithcraftmotorsports.com if i were doing a 383. he has great prices and customer service.

ah, i would like to keep the same block in my car.... when you do a 383 stroker kit, doesnt it keep the same block? it seems like it would be cheaper..... and from what i have been reading.... 383 is the best size to go with on the stock block....

i dont really see the need to go getting a new block stock one should hold about 600-700 horse... and when i start getting into that range..... then maybe i will think of getting a better block to go with the 383 stroker kit..... my buddie had a stroker kit on his 66 impala with a BDS supercharger..... it was putting out over 950 rwhp...... its not like having a smaller motor is a bad thing..... look at the supra... 3.0 inline 6-cyl putting down in excess of 1000 horsies..... i think stock block on my Z will hold up to what i want to get out of it... also i bet i will get better gas mileage out of the car if i keep the stock block.... i know i will lose some with this kit.... but i dont think its going to be horrible....

Also gotta remember our blocks are Aluminum, not iron. That's what the killer is.

ah, yes.... but i think our block will hold a good amount of power before it becomes a problem..... i have seen 600 horse put out 10's....

Yea, I was looking at that thread earlier. Lots of great info. I guess I'm just still wondering if stock heads are going to work at least decently with a 383 stroker setup. I just bought some stock heads off someone else for dirt cheap so I'm going with those.

hmm, i'm hearing about 500 horse with a 383 stroker kit stock heads cam with headers.... not bad..... new intake mani would probabaly give you some nice horsies on top of that... like an ls6 intake.....


still shopping around tho... not going to buy anything till i'm sure

you have to look at the overall picture, when you add in the companion mods; heads, cam, injectors, pump, TB, intake, ect. the price difference between a 383 and a 402 is minimal. yes your keeping your old block but its still gotta be pulled, stripped down, machined, decked, line honed, ect. an 402 iron base shortblock will run 3500 no core sans shipping and tax. an aluminum based 402 will run 4k no core also sans shipping and tax. and since you still have your old shortblock it can be used as a back up motor, sold as is, or parted out.

thats just for the block tho... no internalrs or anything right? ($3500 and $4000) right?

thats for a fully machined 402 shortblock. SDPC and SLP 402 shortblocks can be had for ~4k; thats block, eagle rotating assembly (4" forged crank, 6.125 forged rods), off the shelf pistons (diamond flat top or dish), and bearings. block machined and ready to go with everything already assembled.

like i said, the price difference is minimal.

I see what you're saying, but I've already got tr 224 cam, ls6 intake, ported tb, ls6 pump, double roller chain, ti retainers, and comp 918's. So, I wouldn't be buying all that stuff either way. I'm also keeping the stock heads (porting/polishing them AT MOST). So, it's basically the difference between a 383 kit and a 402 block.

well, then why even bother doing a 383 if your gonna do it half *** :shrug:, H/C/I are whats gonna make the power; a good set of heads, a new cam to compliment them, and a 90/90. i really dont see the point of doing a stroker thats barely gonna put out more then a properly spec'd h/c/i 346. yes i know the added displacement will have more power under the curve, but not much more with a weak top end.

.........because I just embedded a valve into my #8 piston and the rest of the pistons are also scarred by the valves due to improper timing So, I'm going to have to hone the block anyways. So I figured if I'm already gonna be boring, resleeving, and buying new pistons/rings, I might as well just go with the 383 kit. What do you think? Is there a better route to go?

jrp

iTrader: (16)

oh, that was your thread?

considering your circumstances thats not a bad way to go if accept the facts that you'll be making alot of sacrifices in power if your just gonna swap over the old cam, valvetrain and intake onto the new motor.
