L9h/L92/LS3
I'm looking at buying a complete engine and trans combo to put in a 1971 C10 pickup. I do not want to do crazy mods to the motor at this time. Maybe a cam and some springs etc...
Will all of the mods for the L92 work with the L9H? I dont mind keeping the VVT at this time.
LS3 would be nice but cost way more to pickup.
Is the L9h or the L92 or even the LY6 more sought after for modding?
Thank you

L9H is just the flex fuel version of the L92, which means bigger injectors. The differences between the L92/L9H and LS3 are the LS3 has flat top pistons a forged crank, lightweight intake valves, and does not have vvt. Both use 821/823 casting heads. LS3 is 10.7:1 compression, the L92/L9H is 10.5:1. What i did for my 92c1500 was get a L92 and then sourced a 6l90 because they are easier in 2wd form to find then a 6l80.
Good luck with your project.

Thanks for reply!
The current combo I'm looking at purchasing came in a 2012 Silverado and has a 2WD 6l80E behind it.
Which cam would you guys recommend for some additional street-able horsepower? Would you also do springs and some better valves?
Thanks again

Numerous VVT camshafts are available and the ones from Texas Speed come with the VVT tables. Maybe a VVT-2 depending on the converter stall you want to use? The valves are ok for the rpm you will most likely be turning but you could put the LS3 valves on the intake side if you want.
I would do a valve job and replace the springs while you are at it. Heck might as well get the heads CNC'd for more air flow while they are off. Texas Speed has a package deal for all of that if that is the route you want to go.

]If you want to keep the VVT and still do a cam, I'd suggest contacting Patrick G. for a custom VVT cam. Try a SEARCH using the member Cam. He has a L92 with a Patrick G. spec'd VVT cam with good results.
