Default FAST 102 LSXRT or MSD Atomic for 3rd Gen w/383 LS1?

FAST 102 LSXRT or MSD Atomic for 3rd Gen w/383 LS1?

After several searchs I haven't found much dyno or flow data for the MSD Atomic intake with LS1/LS6 style heads. I've see some data on the MSD for Gen IV engines.

My 3rd Gen Camaro can get a cowl hood so fitting the FAST 102 LSXRT shouldn't be an issue.

The 383 LS1 is mild for these days.
229/229 cam
TEA Stage 2.5 ported LS6 heads
Hawks 1 7/8 headers

Input appreciated.

Thank you for taking time to read & respond.

I'd go with the Fast simply because it's proven. If and when the MSD shows to be just as promising I'd then maybe reconsider

if you're comparing the lsxrt which is the truck bread box intake hten thats it all the way. Its much larger than the msd or refular fast 102 which allows for more volume as well as LONG straight runners

The only reports I have seen so far for the MSD have been on the 427 motors. Nothing for the LS1 style or the LS3 style motors.

That's unanimous LSXRT.
Provided it can fit at the rear...have to keep the wipers.

How tall is it at rear...10 to 11 inches?

It's tall for sure. My engine sits very low and is almost against the crossmember, and the throttle cable bracket bolts must barely rub on the hood. It is 10.5" tall.
