L03/LB9 Question...

I know this is probabaly a dumb question, but is there any difference (internally) between the L03 and the LB9? (stroke/bore)

Also, would using forged internals have any benefit on a n/a car?

Thanks in advance for the help.

Re: L03/LB9 Question...

Bore and stoke is the same, cam and heads and intake (obviously) are different.

I wouldn't waste my time on forged internals unless I was going to use forced induction. All you get is a faster wearing bore and piston slap

Re: L03/LB9 Question...

no the bore and stroke on a 305 is the same

and on a N/a street engine there is no need for forged pistons or crank...
