LT1 Intake.. When it ABOSLUTELY, POSITIVELY NEEDS TO BE OVER-ENGINEERED.
I wanted to make sure I had plenty of meat to stud the distributor into.. I think I went overboard.

HA! It can be done. That's exactly what we are gonna do with the LT1 intake for my friend's Vette. We want to be able to still use the big distributor and planned of just cutting all that EGR crap off the back like in the picture. Thanks for posting it.

My gosh man your evil! j/k
That's one way to keep the large distributer. Hell, next you'll probably cut the top off and extend it upwards creating a larger plenum.

With all that cut out, add a couple 90deg fittings and braided line in the far corner...could probably work out a remote EGR. Hmmmm..

If we're doing the LT1 swap, chances are we've read John's site 10,000 times! LOL
Here's mine...

That picture isn't the stock 350 from your '91 is it?

Mines not drilled either in that pic. Instead of worming out the holes and doing it by hand, I'll mill each side on the bridgeport and then drill each hole after welding up the old holes. More work but the JB Weld just doesn't add true support to keep the manifold from cracking & leaking.

JMatlock88,
Looks damn good!... how'd you get the top chromed and without the ribs? They just fill it in a dip the top?
I had talked to you one time over AIM... you had said it was painted black and silver... that... is quite a silver!

7-10 days is very fast in my books!
John, what do you think about the JB weld issue mentioned above?
No, the manifold is atop a small block 400. It will use a stock 400 crank, beefy rods, and forged TRW's. She'll be topped with afr 190's eventually, but those are just stock castings in the picture. I have a 200 N2O shot ready as well. See ya!

A remote EGR sounds like it would be the ticket. I've often wondered, why this was not done before. The way I see it, the small EGR hole in the LT1 manifold doesn't even have to be blocked off since this is where the exhaust gas enters the intake- no need to worrying about anything being pushed out from there. Additionally, the area where the original EGR valve mounts could be modified instead of blocked off. I though maybe adapting the upper hole (the only one that would need to be blocked off) to some sort of pipe plug, then using an EGR system off a 2.8/3.1 would allow a remote EGR system to work. So what do you think, I am missing something? You've guys made it this far!

(JB Weld) because I was worried about the extream heat required to fill the holes might warp the machined surface that mates to the head.
As far as filling them I don't believe it's even necessary except for two of the holes where the new ones are very close to the old ones. I did it for cosmetic reasons only and to be sure it won't go back on a LT1 ever again. After I painted the intake you can't even see the JB Weld.
If you really want it filled right without the heat and warpage issues would be to tap the holes and locktight a bolt in from the bottom and grinding the head off flush.

On average... rails, TB, intake with injectors will sell for around 175-200 on ebay. Give or take a little depending on condition.

i just have to ask is the heighth right of the distributor? also what are you going to do about the water passages? I take it you are not trying to make this a street driven car? This has got to be a motor that takes life 1/4 mile at a time. Just let me know how the thing runs.
