Awesome build. Im considering a Zetec or Duratec in my MGB. Havent decided what build to go with yet. I'm getting a lot of great info from this. Keep it up and good luck.

Not sure the collector of that exhaust will "flow better." That abrupt change in the collector plate from 4 to 1 creates a significant pressure drop.
Thanks for the input! I'm glad you've enjoyed reading about the build. I'm still willing to bet that any aftermarket shorty header will outperform the stock manifold of the same design. Overall, using a shorty header seems much easier than making our own header or adapting a 1.8L Miata header.

I guess we should tell these guys that their header doesn't flow well.


Kidding aside, 4-into-1 open collector is a proven design that works well.

Not to mention the packaging issues of doing anything in an MGB. Keep in mind that the engine compartment is tiny so there's not a lot of room to work with. A shorty design is the easiest way to go.

We installed the cam gears on the cams and started checking the valve lash. It looks like we'll be able to use most of the buckets we already have after I rearrange them. I still might need about four or five buckets so I've contacted some people that I can hopefully buy them from.

I'll post some photos of progress later this weekend.

VERY nice. I'm loving this. I wish my Dad lived close enough to help with mine. I'm jealous of you guys there. I can't wait to see this done!

Oh, and is that tile on the floor in your garage?? How does that hold up to having engine stands rolled around? Do you have a mat for jack stands when you use them?

great thread. Your back and forth banter is quite enjoyable.

My Dad is not really a car guy, but he has helped me with some of the larger tasks I've tackled (suspension, clutch). They are good memories to make; a father and son working together.

the collector on that is completely different that that shorty zetec header. the collector on that car costs more than the whole zetec header. the merg collector on that header is not cut pipes with a flat piece welded inside like that zetec collector and they use a megaphone after the collector to help with velocity.

those two headers can not be compared. just look at the difference a true performance merge collector

that shorty will flow a little better than stock but it will not make a difference that you can really feel. but it does look a hell of a lot better.

and for the OP i'll get back with you very soon about those buckets. i have to get them out of the attic and measure them

^^ That's some very nice welding and polishing work, and your right they can't be compared to the shorty.

Thanks! I've definitely enjoyed working on this build with my dad so far. We've worked on a lot of cars together but this will be the first one we're restoring/modifying together from start to finish. Your build is going to be pretty epic for FF. I'm looking forward to seeing more progress/photos.

As for the floor, I'm pretty sure it's peel and stick tile (vinyl material). It's been very durable so far and the engine stand and jacks roll on it without any issues. It's pretty easy to clean oil off of too.

Thanks for the support. I'm glad you're enjoying it. I didn't think this thread would really gain any interest when I first started it on FF but you guys have been extremely helpful and have good input.

I wouldn't read into my dad's joke too much. He knows what he's talking about but he's a bit of a forum troll sometimes. I'm housesitting for him this weekend so I'll punish him by drinking all the beer in the fridge.

Regardless, the shorty header is the easiest option for my build because I'll avoid a lot of clearance issues with my small engine compartment. It's a compromise in performance but it makes the swap a little easier. If I were truly building for power, I would have gone with a V8 swap. I have to agree that it does look a lot better.

I really appreciate you looking for the buckets. Currently the .685 is the one I need the most. It would definitely help us out a lot. I think I have the other ones covered. Just PM me when you can get around to it. Thanks again!

Crap....all my beer is gone! And has been replaced with apple ale!

I really wish we could get the SVT header into that chassis, but there's no way it will fit without hacking it or the car up. The shorty is the best compromise because it fits the car.

Early on I think I said the stock header was probably almost as good, but Bling wins out this time.
