hey all
looking at buying a 383 stroker kit for my ls1 vt ss
i dont know a whole lot about this so im just wondering what your thaughts are
my vt is pretty much stocko engine, only extractors exhaust and a ls1 edit
so first im wondering if i should even bother doing it to a stock engine or m i going to have to change a whole load of other components in my engine ?
also would like to know things about:
power gains
anymore ups and downs ? if anyone else has fitted a 383 kit to ls1 ?
and labour costs ? im thinking its gunna be a allot ?
thanks lads
If your gonna go 383, don't use the cheaper kits like COME.
Eagle or callies stroker cranks are good options, i personally went callies.
You will need pistons and rods to suit the 4" stroke crank, again eagle or callies for rods,
Pistons - there are plenty out there and choice will depend on application ie boost, N/A
But Diamond, Eagle, Ross all good. You will need to specify compression ratio with piston choice also.
To get the best out of a N/A stroker you will need a decent camshaft and valve spring/pushrod/timing chain/oil pump upgrade.
Then theres the ARP mains stud kit and head stud kit.
Don't forget Machining for new pistons etc, balanceing and assembly
$$$$$ add up fast !!
L98 orLs3 wont make same power as 383 unless modded my 383 has got 450RWHP 335 RWKW(STD T/b,intake manifold) and pulls hard, nice and torquey .It is expensive though and drinks fuel.dont forget clutch if manual or rebuilt box if auto,Heads/cam, fuel systems etc It really does add up but you cant beat the sound of a cranky N/A motor.Good luck its all good fun
this has been covered before all the street commo forum and the ls1 forum and l98 woth a cam is cheaper and can make more power
