Drilling magnum heads for LA intake

[Cuda416]

Your suspicion is correct

Figures, but still, the size of the holes on the intake alone would allow for some "wiggle" room in "slight" positioning error from drilling, as long as the angle was good. So maybe not doing it by hand but doing it with a drill press seems possible.

A better idea is just don’t use the 6 pack intake. They’re junk.
Let the comments roll!!

looking good > going fast

fight me.
(remember i am three raccoons in a dickies uniform. and i cannot confirm we have all had our shots)

Just set the intake on there and use a 3/8n chuck drill and drill away ....just kidding ( but you know someone tried it LOL!)

Hey, people have done better with less, lol

 

[Cuda416]

it is not. i don't recall what it is right off, but i know it's not 90.

Quick google shows it to be approx 7 deg. I found 7 and 6.75 from two different people using angle finders. So, confirmed, NOT 90.

Na you’re to pretty to fight.
I’ll open another can o worms here. If I had the 6 pack and wanted to use it on mag heads, I’d drill the intake in a heartbeat. I’d fill the La holes with the old everlast green machine and hand drill the flanges to 3/8. The 5/16 bolts will drop right through with a washer. Doesn’t even have to be very precise. But I’m not a sticker for resto stuff.

While I wouldn't do it to an original, I'd probably do it to an aftermarket one. I'd probably tig the holes closed though so bead blasting would make it "look stock".

Just so we’re clear the “everlast green machine” is my tig. It’s green

Honestly in a pinch and on an Island or Alaska why not? Drill em and tap em it could be done...I think Id drill and tap at 2 points and get bolts in so it wouldnt move then do the rest etc.

Hah! Fair, I was thinking epoxy! I was reading (skimming too fast) and read "green" Doh!

It's the Jar Head in me. Improvise, adapt and overcome.

Point the finger, I gotta know who it is!

The asswipe in the situation here is the member who passed it along to a member with 1 post. Guys have been putting 100% of the blame on the douche that kept it. Why on God's green Earth would anyone trust a brand new member with a post count of 1? Longevity and posts make a difference. I don't want to insult the intelligence of the asswipe member who loaned it to the douchebag but damn, that was pretty dumb.

This is the douche.

Contact chris@bhjinc.com for the BHJ jig. It's a couple hundred dollars though. If you're buying new heads you can get a better casting in the EQ CH318B with LA bolt angle from Engine Quest.

If someone needs the jig a month from now, I can make one. It ain't rocket science, I'm just busy right now.

More like three retarded raccoons in a trenchcoat.

So, I’m sorry for not being able to provide a jig, but magnum swap website says Hughes will accept your intake and drill it at a reasonable price. What that actually entails, I don’t have the foggiest

And you'll bet it back when?

Probably faster than Canadian Cameron returns the jig

Did anyone see the tipoff for a ripoff? the guy said "with no deposit..."

The area code for Moncton NB is 506 not 902 . 902 is for PEI and Nova Scotia . i will talk to some friends and see if he is known .

Thanks for all the replies I purchased the 408 crate motor at Summit Racing with magnum heads on it I think the best thing to do is take a 2barrel intake with gasket and install a sleeve in each hole for a drill and mark the depth on the ends

I got a jig that worked well for me. Drilled to 5/16 thread so it keeps the magnum threads and the new smaller size la threads. I live about 2 hours from you I would guess. I'll see if I can dig it out
