Pray Performance reviews the GPI Drop In rod/pistons combo for the LT engine

[@joshuacayea7810]

Agree 100% on the quality of the GPI drop-in kit. I’m making 1059 WHP on this setup (Whipple 3.0 with LPE DI fueling) and have been over 3 years at 900+ WHP on that GPI setup. Top shelf stuff and amazingly tough for a drop-in kit.

Did you have to pull the motor and balance yours?

[@joshuacayea7810]

@@sheldor73 We pulled the motor in anticipation of having to balance it but didn’t end up needing to. My shop weighed the piston/rod assemblies and the weights were amazingly close to OEM. They reassembled everything with careful attention to all bearing clearances and it’s been very solid for simple “drop-ins”.

So, since you have the block machined, do you buy the 4.070 kits or stock bore?

[@brieftactical2125]

does this work with LT1 stock block or any prerequisites needed to actually install this (just wondering, not actually planning to put this in an engine)

[@GTOGregory]

Thanks for the insight about the balancing!

[@bowhite1293]

GM has always had machine work thats "good enough" 😆 Back in the day when I worked in a machine shop almost every SBC rod had to be redone for a rebuild. Once it was remachined they super rarely needed to be redone a second time on the next rebuild. I seen it first hand why a few years in. We had a guy buy a brand new GM Goodwrench 350 and wanted it blueprinted and a good street cam and heads. Sure enough the rods needed redone. Brand new.

I agree with you 100% I did my own build and did same kit had vibration at higher rpm's definitely need it all to be balanced now everything is apart getting it done wish I knew what I know now ! I really think they should stop calling them drop ins. Like me thinking it be easy to drop them in and be done save time and money but not the case

[@TheJoe111599]

I'm very glad I saw this video before getting the pistons/rods ("drop ins") in the mail. Should be getting them any day now. GPI even says you can install this kit with motor still in the car. I guess you can but may have issues with vibration. :(

Wow! He checks the small stuff.

[@jpalmer3089]

Thank you sir! Love the facts.

[@AlfredoLT]

Would this work with the Stock heads on a 2014 Silverado 5.3

[@gtppower]

have you done one of these in LT2 ???

[@floridanick]

🇺🇸👍🏻 thanks Brett

[@johnprince7510]

Are you saying the LT machining is worse then the LS stuff?

[@nickswizzy]

Also interested in this

[@Mnkczx]

Pretty much

[@Cultofpersonality09129]

If you’re going to send stuff to the machine shop, the point of a ‘Drop in” kit is useless.

[@prayperformance5137]

Actually not at all. The parts are still the parts you would have to run anyway. It is not the parts fault GM sucks at their job.

[@sheldor73]

Absolutely useless you're 100% correct.

[@2daaxe4head]

The cut out is not for the spark plugs

[@snooka2484]

Sub for sure 😎🍻

„SBE“ != Stock Bottom End
