What iks the largest header to fit the thirdgens?

Looking for 1 7/8" primaries and 3 1/2" collector if possible.

Hooker makes a set, but I called them yesterday and they said I'd have to run a powerglide, move my engine to the right, and cut into the crossmember. I won't run a powerglide and they don't have any for the 400/350 combination.

Anyone else know of any companies that make headers this size for our cars?

 

Why do you need 1 7/8 inch primaries? The Hooker 2210 1 3/4" primaries are adequate for nearly any small block.

 

Well, if this is going on a motor that runs the times in your sig, I would say dont do it. It will hurt more than help.

If by chance you have something that needs that big of headers(kind of doubtful) then hedman makes some 1 7/8", and some 2" primaried headers. I dont know what the collector is but I believe it is an adjustable race style collector. They are called hedman huslers.

Thanks, I'll try giving hedman headers a call. I don't mind doing minor modifications, but having to change by transmission won't help.

The engine I'll be running is the same as a local friend, and coworker. His car recently ran 9.40s in a 3500lb car @ 15lbs of intercooled boost. It's now been swapped to 22lbs of boost, as well as reduced weight. He's expecting 8.80s.

This is the same engine I'll be running except in a lighter car. He's running 1 7/8 headers, so I was trying to find some that I'll need as well.


While 1 3/4 heads are great headers, from what I've read they are pretty good up to around 650 or so horsepower, while his car is probably around 850+ to the rear wheels.

I'm just trying to get some ideas, headers aren't my main concern, was just trying to find out what options I had when the time comes.

Thanks.

 

What are the specs on this motor? That will be a heck of a change from 14.2's. How is the rest of your car setup, because if it is stock, I could see it tearing its self up real quick. You are going need a built tranny *cough* th400 *cough* and a strong rear end(9" or 12 bolt). I also hope you have subframe connectors and a good suspension.

I just looked at your website and it does look like you are on a good start for that. Just a question but are all those tpi parts yours down at the bottom? If so WHY?

Ben

 

Ben,

Yes, the rearend has alrady been purchased, and next is the spohn TQ arm / Crossmember, turbo 400, new driveshaft, and the rest of the suspension additions.

The engine is 400 with an ATI D1R on it.

 

What kind of fuel system and heads? Is the motor all forged? What type of rotating assembly?

Ben

 

Eagle rotating assembly, with wiseco pistons.

Two aeromotive fuel pumps going to 96lb injectors.

AFR 210 heads.

 

tpi?

 

No single plane converted to EFI with Accel Gen 7 Computer.

 

Oh yea,
The TPI parts are all mine, I buy and sell TPI units. Polishing, Powdercoating, and cleaning them up and such. So, those were some that I had on the shelves, just took the picture for fun.

 

A friend of mine runs a 427 EFI smallblock & has the Hooker 2210s on it. BTW, its rated at over 700hp & runs 9.50s all day, NA. His car was on the cover of GMHP last year.

 

Ricktpi, If I have to, I may go that route. But I still think there will be more power gained from running the larger header.

 

Yes, with a 1 3/4 primary you can still make a ton of power, but if you are putting all that money in them I would go with the hedman husler headers and get the bigger primaries. Might as well not waste any power. lol.

Ben

 

Ben, I agree. I see no reason to hold back power if I'm looking to buy the headers. If I already had the 2210s, I would go that route.

 

I just wanted to say you got one killer setup in the future.

 

Thanks mark, just gotta do some saving for a little while.

 

I believe Ed Quay makes large headers also. I couldnt tell you how well they fit but..... http://www.edquay.com

 

Stahl does, too. http://www.stahlheaders.com

 

They also say it won't fit stock frame & engine mounts.
