Well i finally got my LT4 intake and 58mm Throttle Body on
here are the pics?
Bought it used thinking it was an LT1 intake then i looked at all the castings and numbers and turns out it was an original LT4 intake, so i had it acid dipped and powdercoated Bengal Red then ported it out to 58mm for the new throttle body.





The old intake (For sale)

Tell me what you think? getting ready to leave wednesday for the big POCI Pontiac Car show in Tulsa, Oklahoma

 

hell ya!!! its always cool when you find out you bought something better than what you thought. what kind of gains did you get from the LT4 intake i want to some time down the road do that to my car, but i figure i should do it all at once and do the heads and cam with it.

 

So how do the intake ports line up on your LT1 heads?

 

they were bigger, but when i had my motor built they opened up the ports in my heads and intake, so they were pretty close

 

Your intake manifold ports were bigger than the intake ports on your heads? I hope not

 

What good luck lol i bet your goin to see some gains

 

My dad will be up there for the POCI. Him and some buddies are leavin wednesday and trailerin there GTO's up there.

 

how much did this cost you because i really need one.....

 

How long did it take ya to get the new mani on?

 

I am leaving wednesday with a car club, is he with DAPA?

took about 5 hours in total

 

Haha yeah, were part of DAPA, hes the guy with the gold 67 GTO, he will be pullin it with a black silverado 1500. If you are leaving with him, will you ask him to snap some pics of your car for his son? I have seen a couple of pics, and your car looks REAL good!

 

Stock for stock the LT4 internally is the same as the late LT1 intakes and if you machine it so that it bolts to LT1 heads then you machined off all the potential gain it could have had with LT4 heads because that extra material is what is needed to port match and seal to LT4 heads.

GIZMO posted this pic awhile ago to show the difference.

Seems no matter how many times we try to crush the LT4 intake myths though there are still lots of guys who believe it is more than it is.

 

^^^ But he didn't pay a premium for it nor was he looking for it. Just wound up with it. He probably gave what, $60 for it????? Personally I would have tried to sell it for what I could get out of it and then buy the LT1 intake.

 

I was replying to the guy who wanted to know how much of an "upgrade" it was. That is why I quoted him specifically rather than just replying to the thread.

 

Oh ok. Thought you were referencing everyone.

 

Well it is something everyone should read and understand. Maybe if we keep trying eventually the realities will be understood.

 

I tried buying one at retail when I realized they were going through the roof but Summit was already out. I wanted to hop on the bandwagon and sell for $$$$$$. I didn't score any, I was too late.

 

no thats not what i was saying. i was saying that i want to get the LT4 intake with the LT4 heads and then a cam with that further down the road.

 

Keep researching and you will find LT4 heads with a 350/355 is still a mistake.

 

looks good. My advice, Rip that POS TB plate off the TB and get a good one. That thing looks like ****
