after 10 years...

[Paul A]

I installed the 2.8 V6 in Ol Blue over 10 years ago. The engine is a stock, low mileage unit from a 1977 Mustang Ii. The headers are from Jose. The tranny is a Toyota W58 five speed. The combination has served me well. I am beginning to do some upgrades. After searching for many years I finally found an Offy manifold in good condition. I also found a Carter AFB 4331s carburetor in good condition. I have a set of reconditioned heads with 2.9 valves. These items I will install on the existing engine - great compression, no leaks. I will upgrade the exhaust, finally running duals after all these years. I also located a good used 3.89 pumpkin to swap with the stock 4.22.

I had to relocate the fuel line and brake line from the stock location in the X frame. That job is finished and I can now drill a new hole for the 2nd exhaust pipe. Once finished a local exhaust/muffler shop will reconfigure the header to allow a more straight back exhaust system. I expect a bit more power and a better breathing engine when all is finished.

Paul, Glad to hear you are making progress.

The Jose headers are what caused me to design my "Straight Back" ones. Did not like them sticking out the sides and very difficult to re-route underneath with adequate road clearance.

Whle you are about to install the heads with the 2.9 valves make sure you plug nd redrill for 10 mm 1.5 thread header bolts so that you can secure the bottom of the header flanges (no leaks ever again). I have the "How To" in my PDF.

I have gathered several sets of the jose headers over the years from V6 guys that bought my design headers. After lots of figuring on how to re-route, I have recently figured a way to modify the jose headers so that there is an easy way to "turn" the collector "straight back".

If you would like send them to me and I will get them modified. Perhaps you can do your own (DIY).

Here some pictures of my Modifications.

I modified a set of those for Nick think my way a lot simpler.

Pete, can you add some pics of the hole you made for the passenger side exhaust? It would help with my alger project.

Paul, is your AFB the itty biddy (about 410 cfm) 4 bbl? If so, you have what I consider the best carb for the little V6's. I had one on an AMC 232 way back when. It was a dream of a carb. Put it on Dad's AMC 360, same performance profile, except of course, it ran out of breath way short of the engines potential. But it convinced me that a good carb cares little about the size of the job, it just does what is needed. Also, I must commend you on your choice of transmissions. It shifts way better than the popular Ford sourced units.

Bill, the small 400 AFB was an aftermarket carb, #9400. I had one on a Buick V6 in a Jeep. The one Paul has is probably around 500 cfm used on 65-67 Buick 300 and 340 V8. He will have to jet it down, The MGB site has jetting info they use for the Edelbrock 500, on the 2.8/3.4 GM V6 and 215/3.5 Buick/Rover V8.

Edelbrock part numbers:

Rods: #1441 .062x.052”

Primary jets: #1421 .080”

Secondary jets: #1423 .086

Hi Dick
Was there an. adapter from the 2.8L to the Toyota W58 5spd?
At 55mph my 2.8 turns 3200rpm which is too hi for me....and yes I checked the the tach against a new digital unit and they were in total sync.
What are you turning at say 60mph or are you not yet terrrorizing the neighborhood yet>. : - )

I will when finished. I hope it replicates this one...

Paul A here I had a custom bell housing made by Conversion Components It was not cheap! I do not know if they made any more.

Have you looked at Tiger exhaust routing? Photos attached.

Here's what i did for my Red GT with the A4LD tranny....

Carter specs I measured my bore diameter at 1 7/16ths therefore a 400 cfm carb

Paul, I wasn't sure on the cfm but the jets will be richer for the V8. The one's I listed are proven to work well in a V6 with cam and headers.

 

[Paul A]

thanks!

Here's what i did for my Red GT with the A4LD tranny....

The notched battery box is what I was hoping to avoid.

 

[DanR]

You can, but extremely tight routing. The one pictured was my first attempt at modiftying while in the Alpine. It can be done but lots of efforts pays off. Much easier with removal from the Alpine and doing it on a bench or purchasing one of my fabricated ones.

 

[Aladin Sane]

My current plan is to run as large a single pipe as I can. It will be a little restricted, but I wont be lacking for power.
