My American Racing Headers got here (pix)
In the meantime, here is the car with just the lid and the GMMG.

The next video (hopefully within the next two weeks) will have the ARH long tubes, a TR224/224 114, and the LS6 intake (along with supporting mods like the oil pump, timing chain, etc.) Hoping for between 380 and 400.
If you're not sure to do them or not, don't think twice, any cammed or long tubed car should have poly mounts.

Those look just as TIGHT!, as mine. I went with LS7 D-flange and 1-7/8" Long tubed w/ 3-1/2" Y collector. I resently put them on my stock upper and lower end LS1. Major difference from the stock manifolds. I haven't dynoed it yet but can tell my peak HP/torque moved to a higher rpm. They are originally for the LS7x I'm building slowly, but surely.
The passenger side slid right in with no problems but the driver side took a little finessing. I had to pry them past my #2 head bold and wiggle it past the steering column from below
(not recommended if you care about scraping your steering shaft). Put them in without taking anything out. Oh, and you might want to trim 1/2" off the rear part of your lower A-arm, between it and the header to prevent contact with the header.




Great Job ARH!
