Were building a street/strip 340 so i can introduce my kids into Dragracing.ive been into it for some time and i usually put forged pistons in my engines but im not looking for them to hop in a 11sec street machine, ya know? Just a healthy .500+/- cammed 340 with the obvious goodies, auto and maybe 4.10 or 4.30 gears. ThanksI dont have an answer on which ones are better. It really depends on what your built Intel's. But I will say this Kbs are lighter and usually have a higher compression height. But the speed pros (so I have read) are stronger. And they are closer in weight to factory pistons in most instances. What are you building? 318 340 or 360?
Thankyou Gary...so basically spending the extra $$$ for the KB name over SpeedPros, im just throwing my $$$ out the window. Its a budget build so that answer i approve of! Thankyou.Again, the brand does not dictate the strength... the type of piston does.
Speed Pro, KB, Mahle, Diamond, Wiseco, Manley... all make both forged and hypereutectic pistons. In every brand, the forged style are the strongest.
You shouldn't choose pistons by the brand name!
That is good, but making sure of your tuning to avoid detonation is more important.....and by the way, i do have a REV-LIMITER and i do plan on using it!
Not 11's.....maybe down the road that would be nice! Were talking a 15 and 17 year olds here....a low 13 or high 12 would be plenty fast for first year drivers.....at least from a fathers point of view!! Lol.11's, on pump gas? I would think stock pistons would be fine
He actually said that his kids shouldn't hope for an 11sec. street machine... so yes stock or hyper would be fine.
As long as he stays out of detonation.
Edit: NM9 has it all covered.

Ahhh. Got it. low 13's or high 12's I certainly wouldn't buy new pistons unless the cylinders are bad and you must bore it out. Speed pro work just fine and are cheaper.I meant 'hop in...' and corrected it since. Thanks
Exactly.Speed pros are strong, been abusing them since 2012 in my old 360.

So the OP will understand: Do you mean you want it balanced to a much tigher tolerance than factory (even if it is stock weight parts)? Or are you recommending he go to lighter pistons/rods and rebalance for that to get to lighter rotating weights?One thing I'll correct is the part about balance and stock weight pistons. You dont want factory balance, nope... especially if you have the chance to correct it.
Factory balance job wasnt the best. You'll have less wear the better the balance.So the OP will understand: Do you mean you want it balanced to a much tigher tolerance than factory (even if it is stock weight parts)?
