What exactly is it?
like an entire new block??

Sorry im dumb

 

your block bored .030 with a new crank, pistons, bearings, and rods. the complete bottom end.

 

cool
how much does a kit like that cost?

 

www.nu-tekmotorsports.com

If you don't know much about them the best thing to do is to let Nick from Nu-Tek build you one.

Click on strokers on that page for LT1s.

 

you can get a good kit for 1800 from sumitt. comes with everything you need except the bore and some are even balanced for you. but, like they say, the more you spen, the better it is. on the other hand, if you want to spend the 5 grand, ill buy one from sumitt and you can pay me 5k for it.

 

Budget and Stroker do not belong in the same sentence.

You may as well port/polish the heads, do a larger cam, plan on a computer retune, get some longtubes and appropriate exhaust, make the appropriate intake mods, get some larger injectors, and the list goes on and on once you start in on it.

Also, with the torque of a stroker, you may as well plan on a 12 bolt and some ET Streets or slicks, you will end up needing a six point bar to run at the track legally, and you should rebuild your transmission/clutch now rather than wait to blow it on your first pass.

Just my .02, not a flame.

 

In a chevy 350 like the LT1- the pistons travel up and down 3.48'' in a 4'' bore

we bore it to 4.03 '' and use a crank with a longer stroke - so now the pistons travel 3.75''


the real advantages of it are
more cubes
longer stroke tames the cam a bit
When doing a rebuild, a 3.75'' crank costs just as much as a 3.48'' crank so why not get a 383

With the advantages listed- a 383 will not make much power than a 350 with the same internals and heads. The bottom end is not where the power is- its in the heads and cam combo. The cubes help, but the heads and cam combo associated with the combo is what really gets you moving


If you are not expierenced engine builder or building with someone who is-
its probobly a good idea not to build it yourself the first time


With that said- I think combo motorsports is the best place you can go to for a 383-
I honestly think they are one of the best- if not the best- LT1 tuners.

All for $5895.00 Shipped
That is proboly the same price you would look at for just buying the parts and machine work and head work.
Hell of deal IMHO. and its all forged so its pretty God damn strong and ready for lots of nitrous

 

To give you an idea of price differences:

I built my 383 for $7000 u.s.

Thats not including the rad and other crap.

The guy I built it from charges $2500 u.s. to do a straight 350 rebuild using the same crank.

 

your 383 is a bit more "high performance" than a strait 350

 

True.

 

yeah your (our, pretty funny how similar our cars are) 383 can definatly beat up an OEM 355 and take his girlfriend
