These have helped produce over 500 RWHP N/A with a mild cammed 422 and over 700 w/ TNT kit. If they work this well on a big cube small block they will work great with just about anything!! Only selling to help squeeze out as much as I can with the bigger cubes...going to 90mm set up and larger diam. headers, a hopeful gain for the strokers.

Mac's have had outside of primary tubes professionally welded. Ported to header gaskets and 3 bolt flange mod. These will flow!!

They have also been coated using an industrial offshore aluminized coating to withstand anything you can throw at them...Will not rust!

Also have custom y-pipe with flowmaster collector and will throw in the cut out!! Everything is in great shape...

"Tweeked" Mac's-$350.00 or $450.00 with custom Y-pipe, Flowmaster collector and cut-out! Hell of a deal for all this!! (Sale pending but 1st person with cash in hand get's em)

 

Dennis, what are you up to with your car? No good, I'm sure.

TTT for a good deal on headers that are in excellent shape.

Thanks Mike! BTW still have the lugs and caps I left you a message about last week or so...

 

Oh yeah! I haven't had a chance to even test fit the wheels yet. With my wife starting another school year, things in the Casa de Chupr0kabra have been hectic, to say the least. If you get a chance, swing by G-Force tomorrow (Dyno Day). I'm planning to go, but don't plan to get any pulls (but we all know how plans change). I just want to go and check out other people's rides.

DJ please stop de-moding your car for the love of god!
