Default My 1968 MGB GT 408 Build

I've had this MG running around with a JDM sr20det for awhile and have decided to go all out with the next upgrade.

Will be putting my sons old race motor into it

specs:
LQ9 408 iron block
dragon slayer crank
Diamond pistons
PRC 237 heads
Texas Speed cam
LS6 intake
Nasty nates fuel rail
All ARP

My son had a F1x blower on the engine while in his Vette

Now it's going into my 2200# MGB






here are a couple vids of the engine



Should be exciting!

That thing is going to be a handful, sweet build! Also, I really like those Chevrolet valve covers for some reason - maybe it's the vintage style.

Thanks
Those cover were a lot of work

they come just open on the inside-we actually built baffling into them like the stock covers have to keep the oil spray under control

Oh wow, get the process down and start producing and selling them. They're sweet.

Are you going to be running the Procharger in the MG?

Not the F1x, but might look at the YSI in the future-First have to look at the traction issues

Finally have something to update. We got some nice weather and it was back into the garage.

Had to modify some things on the engine-
I blocked off the heater hose ports on the water pump- going to be a fair weather car so not needed
also got a straight water neck, as both the neck and hoses ran into the frame rail of the MG

I'm using C5 Corvette accessories, so all I had to do was notch the alternator bracket and it allowed the the alt to
fit under the hood with no clearance issues

By using the Vette pump and accessories it allowed for a shorter install as they are tucked close to the block

Added the C6 pan for clearance (shallow Pan)

you can see where I cut out for the exhaust- the black template will be stainless trim rings I'm having made

started on the headers-Boy, do they take patience! Just MIG tacking them at this point and then will got back
and TIG them for a nice clean look. Hope to have them finished in a week or so and then sent out to be Jet-Coated

Finally got the passenger side finished & tacked

Now to start the drivers side

Is there a science as to the location or distance when installing the

o2 bung in the collector?

Default finally an update

Finally have something to update

I got the firewall filled in and decided to install the actual engine & tranny
Got it all mocked up and installed
Headers look great with the Jet coat
Plenty of clearance all around
Now to take it apart and get the engine bay sealed and painted
Hope to fire it over in about 30 days

Decided to start going through the harness to make it a stand alone.
made up some small decals to label each wire several times along it's length
Made them blue and red for connector

This should help more then just tape and a sharpie



It's labeled on both sides of the flag





Took a while to get them all put together<br/>but have both blue & red connectors

This is awesome! Looks like you will have a very well sorted out ride when you are done.

Love the MGB GT. I've seen GM V6 swaps in these, but never anything like this! This will be an awesome car when done.

Best thing I've seen on 02 location is around a foot at least after all the pipes collect into one.

Helped a friend stuff an old vortec 350 in one of these back in 2000 or so, digging the build. Even crazier is noticing your location, surprised I haven't seen it out with the sr20det setup.

And yes it will be a handful traction wise.
