Got the engine mostly together.  Still need to finish the rest of the accessories, oil pan and rockers....man this has turned out to be the biggest project I have ever worked on.

Looking good! I'm now thinking when I upgrade the engine I'll make it an LS based conversion. No time soon, though.

Updates....Man life sure gets in the way sometimes :)



After that picture I got the alternator and motor mounts installed.  I had to switch to an Edelbrock Performer intake upper and 351 lower.  My cheap ebay intake did this.  After considerable amount of massaging.  If the injectors bosses where moved 1/4" it might have worked.



I thought about buying the correct edelbrock spyder efi intake and fuel rail.  But at $550...I just couldn't budget it.  I did get my nice radiator and 75mm throttlebody.



Getting my small list of odds and ends to finish this on Saturday morning.  Needs me some 351 turbo power.

Looks good, has to be great to be that close. Seems like there is always something that slows progress.

That's a bummer on the intake. Just sloppy machining/ design.:punchballs:

All the cheap eBay stuff was all the same bad casting.  It would work with aftermarket heads I believe just not the gt40's I have.

What's the difference? I am not familiar enough to picture it.

Check the middle pic of the intake.  The injector boss pretty much dead ends into the head above the intake port!  I had to look at it a few times to figure what I was looking at. 

Those injector bungs are so far off, I'd be surprised if that intake would work with many aftermarket heads in a fuel injected application!  Might work if the heads were ported to a 1262r gasket, and that is a BIG head.

I see the problem, just can't see how a different head would change anything. Strange design.

It probably wont.....just an idea.  I paid $265ish for that intake and a cheap big aftermarket fuel rail.  Im going to sell it all on the corral...That big intake sure would make uber power with a turbo, or super high rev setup.

Couple of more pics....If all goes well this week it will be installed.  I also ordered turbo blanket, remflex header gasket, spark plug boot heat covers. 

Got the lower, upper, and injectors all setup.  I even got the stupid engine set at TDC.  :)

Still have to put oil in her and prime her.

Getting almost there...

Im visiting Fastenal couple of times a week for quality bolts...

Today I pushed the old XR7 out of the garage.  Figured a quick wash would be a good idea.  Its heading to the shop in a couple of days for the 351w.







About half way there....
