Looks good in the car but doesn't fit. It needs a CarbonR type lid.

I have one on a turbo 5.3 in a classic truck.

You will give up a lot of low and mid range power, assuming you could make it work.

It's advertised to fit the C8 but apparently not.

Maybe it's the low ram they're selling? Those short runners are for boosted applications.


This is the hi ram.

I've been emailing Holley's MSD products division to try and get the Atomic produced but only get crickets. Because the intake is rear facing, the fuel line is on the opposite side. I would think it wouldn't take much to notch out the other side to be compatible for the LT1 and LT2..

I Think Cicio Performance made a low Ram fit, not sure what all was involved.

I'd personally would like to see the cross ram work on the LT2. And yes I realize the plethora of issues and challenges it would take. Just saying though...

A different top on the Hi Ram with a shorter inlet would probably work. Something like this?
