Thumbs up MAC Header Spark Plug Access Pics

Since people always say how good the plug access is on the MAC's, I thought I would take a few pics. That way you don't have to just take someone's word for it.

Mac Midlength Header Spark Plug Access:

Plugs #1 and #3


Plugs #5 and #7


Plugs #2 and #4


Plug #6


Plug #8


Hope this helps.

Dan

Thanks.

Yeah, I like to know what I'm buying before I get it, and I hope this helps others to make a decision if they like these headers or not, when comparing them to others.

This is how i changed my plugs with my MACs.

1,3,5,7 - All from above, easy as cake

2,4 - Removed alternator and rubber air tubes, layed across the engine and screwed them in by hand. Tightened them down with a plug adapter, no socket, and a crescent wrench to tighten it.

6,8 - Removed starter and y-pipe (drivers side flange SUCKS) and got from bottom. These were actually pretty easy to get from the bottom with the starter and y-pipe removed.

Make sure you use plenty of anti-sieze, its a great lubricant. I used it on the plugs and head threads.

Total Time: 3 hours and change (including beer and smoke breaks)

I get all mine from the top. 35 minutes total It's nice to have a shortened spark plug socket.

I can get all my plugs out from up top without removing anything, with a normal plug socket. Now for the plug wires i gotta remove the alternator and i loosen up the powersteering pump a bit.

I've messed with plugs on MACs 1 5/8, AS&M 1 3/4, Pace Setter long tubes, and Hooker long tubes. MACs are by far the easiest (IMO) out of that group!

what kind of gains would I expect on a stock LT1 by adding MAC headers and the hooker cat back?

30 rwhp / 30 rwtp. That's what I saw.

I have always recommended the Macs as the best bargain header.

AS&M are the best midlength, and ofcourse LTs are a winner. However, Macs are decent quality and can be had for a good price.
