Ok I started by locating the hole, then predrilled it and increased bits untill I got to half inch, then I went with the 3/4" bit. Word of caution, learn from my mistake, do NOT use a hand drill.

im new to these forums. but here goes . i thought of this same idea when i saw how cheesey the tapping into the manifold looked. i used a set of zz4 heads, and mapped it out where i could go through the stock acc bracket and the head. if i can figure out how to post pics i will.

Looks nice, I want to hear how it turns out. Where did you get to weld up the heads? Like what kind of shop? All the welding places around here tell me they don't want to deal with it for liability even though I say I understand the risks.

Those look like SLP 1 3/4" as well, right?

Where did you get those 90* bends from? Those are nice looking.

Yes they're SLPs, earls russel and nonammers all make 90° AN fittings. Try summit/jegs/whoever. Also another source for cheaper brass fittings is hydraulic supply shops and hose builders.

Are the valve covers the same for an LT1 as an L98? someone said they may be different so it got me thinking.

Do you have any pics of your accessory set up. I'm doing the same thing, but the shop drilled the whole it the front of both insted of the front of the pass and back of the driver.

Same here, I did find a midmount alternator bracket, probably going to run it, It was the only one that didn't mount infront of the head.

Finally getting mine done. Found a place around here that will weld, mill, and drill/tap the coolant holes where yours are for a good price. Sending off my intake to Millican tomorrow for the distributor mods.

I see you got your engine in and running. How is the engine cooling? I have mine ready to install, I'm just waiting on my tranny to arrive. Good luck, your engine looks great.

Thanks for the compliments, I haven't been able to really test the coolant system yet but I should be by the weekend. I managed to blow the nose cone off my starter somehow so that slowed me down a little.

Did you have trouble tapping the heads, my treads didn't turn out that well, the guys at Napa said that the Aluminum used was cheap

I would use 3/8, the 7/16 may be to big for the bolts that hold down the valve cover, at least that was what I was told

Coolant is 100% completely done, holds water, purges air, and looks nice! I'm going to clean up the engine bay and take some pictures, and road test this weekend.
