Cobra Make, Engine: Classic 427, I purchased it May 2005, the kit was bought in 1991. I'm not sure when it was completed! Installed GMPP Connect & Cruise 376/525 with T-56 S/M 3.55 gears about 2 years ago! 1/4 miles is with old setup!

Default Diy (DONE!)



I'm very happy with the job "Pro-Kote-Indy" did on the headers and pipes! Nice people to work with, quick turn-around and fair price, ($513.00 including the ride home!)! index.html

The new engine (SBC 388, solid roller cam, AFR 210 Race Ready heads, RPM intake and Holley 800 cfm carb) for my Cobra has been sitting for almost a year! The hold up has been time and headers! The ones from CRII are a joke for any real HP.

Well it seems I'm going to be making my on headers. I had a few ideas but none panned out! The Schoenfeld IMCA Modified Adjustable headers came close but alas no cigar! IMCA Modified-Schoenfeld Headers I am going to be using their 1 7/8ths collectors (style #9). Hooker 1 ¾ flanges with stubs, 3.5” to 3” slip on reducers and 3” turnouts. Hooker does think HIGHLY of their stuff but it is good stuff!

So, they are going to be stepped headers. 1 ¾” from the flange out about 10”, step up to 1 7/8” and make a 90* turn and into the collector (about 12-15" of 1 7/8” tube) 3 ½” collector, reduce to 3” and into 3” Cherry Bombs (4” by 30” body) and then 3” turnouts! It may be a bit loud but I think it should run and sound pretty good?

With a little luck I should be able to get them all done and tested before the snow flies! When I put it up for the winter, pull it all off and send out for coating!

I also ordered the 700R4 reverse pattern full manual valve body with lock-up and braking. It can lock-up the convertor in 2-3-4, so after 1st it should act almost like a manual trans?

Well that’s the plan, so I guess we will see how it goes!
