I have a 05 Serria, I have 99mm pistons, now I just got as a gift, a 4.000 crank (forged steel) and new rods 6.100, will it fit in my 5.3L block. I know the pistons fit, wondering if the crank and rods will go in and if not what need to be done. What kinda cam do I use.

K&N Intake, Granatelli Mass Airflow Sensors, Throttle body spacers, throttle body, Shorty Headers, flow master exhaust, New PCM by nelson performance.

 

the crank will fit,not sure about the rods however save your cash and stroke a 6 liter they a 4.00'' bore that will make it rip

 

The 6.100 rod makes me think you have parts for a SBC not a GENIII motor. The normal rod for a stroker motor is a 6.125. What does 99mm equate to in inches Im lazy

 

3.897638

 

that looks like a stock 5.7 piston size.

 

How does someone just buy you random engine parts as a gift? Why not just hand you cash and give a pat on the back.


Hey bra, I got you a new set of pistons for your rx8! check'em out!!

Not trying to be rude or anything, It's just not a gift you wana guess at.




(obviously rx8 doesn't have pistons)

 

easy sounds like a tool that is starting crap on this site. look at his post carefully. someone says MM for a piston its usualy a ricer

 

LMAO

 

Piston sizes is 3.905, Rods are 6.125, my brother had a 5.7L GTO was going to bore and stroke it instead bought a 402 long block for it instead. I bought the pistons myself before I got the new parts to make my 5.3 into 5.7.

 

I see.. You got them for him but he changed his mind and let you keep them, now you wana build up.
That I can understand.
