Intake manifold of choice?

Edelbrock intake metal felpro--no problems 71
poston intake metal felpro --no problems 71 o No:

 

I've had no problem with the steel gasket with alum intake and iron heads. I use HYLOMAR around the ports and silicone sealer around the water jackets.

Have also used the steel intake with alum intake and alum heads, however I prefer to make my own valley pan from a used one and use the composition gaskets from TA.

Bruce,
If you made your own valley pan from a used one, did you cut it down... cutting the gaskets off of the pan? How did you secure it in the valley?

Basically cut all the ports off....left the valley part. Attached with sheet metal screws (just 1 each side)....with a blob of silicone on the screw to prevent loosening. This is on a Wildcat manifold.

 

This is also how I do it. It works good!

 

very late reply but-

It was always cracked, very slightly, since I bought it in '91. Engine ran great even with that little crack and two broken pistons. Buicks are tough :TU:

 

Does your engine builder seal the gasket with the recommended sealant?!

As long as it doesn't leak, whatever, but I have no worries about cracking the seal on my street driven aluminum head/valley pan gasket combo

 

I had Jim Weise

Weld a pan to the bottom of my intake (also had him polish the intake too :TU: ), then used composite gaskets from TA. :Smarty: Yes, trouble can develop with aluminum and a tin pan gasket if everything is not just right...

 

Been using metal intake gaskets with aluminum intakes since 1966 and never had a problem, Chevys, Mopars and now Buicks. Maybe this info is put out there by people who manufacture composite gaskets?

My car has an Edelbrock Performer and makes over 500hp on it. The nice part is I can run the stock ram air air cleaner and it all fits under the hood. An SP1 with a spacer requires a hood scoop on the A-body cars and I didn't want to go there. Performer or B4B seem like the best choices. You really don't need one of the single planes until you really get up there in HP.

 

i also used metal valley pan on my edelbrock performer intake with stock 70 heads.works perfect,used silicone on ends of intake also, no rubber seals.i guess the only reason i used alumium intake was cause it is lighter, maybe looks cooler i dont know.well anyways it works good and i didnt have to clean old intake.hehe.thanks RAY

What type of sealant did you all use on the tin gaskets? I am planning on doing just what you have all done. I have Fel Pro MS-96005 stock gaskets. A type and color, or part number would be a help. I have access to permatex products if that helps. Thanks for any help.

Intakes

Just being a Buick beginner I have not tried too many intakes. I like the K-B Wildcat after a little work. I have ran it with a Q-Jet, 4150 and 4500 carbs. I think it is about as good as we get. Would like to try some of the Chrysler intakes with spacers. Actually a intake I have used alot and had good results with is an old OFFY 2x4 with AFB type carbs. Actually did a back to back with it and a Performer a few weeks ago on a basicly stock Stage 1 motor and found the Offy was about 3 tenths quicker in the 1/4. As for a stock intake, just too heavy, reminds me of a cast iron FE Ford intake. A back killer for sure.

I would say that JW may be correct in theroy that the stock manifold will do for a mild street engine, but I sure like getting that heavy piece of iron off my engines. I have run the Performer, the Wildcat and the Offy 2 x 4. Personally I like the Offy the best but not the hot setup for the street I would think but great for a race car. It does take some work and carburetor spacers to run the best but I like it.

Wildcat Intake?

I know I am quoting a really old post, but what is this Wildcat intake you speak of?
Who makes that? In all my searches for info on manifolds that name has never came up.

I'm expecting delivery of my Edelbrock Performer today.

 

Re: Wildcat Intake?

Kenne-Bell developped the Wildcat. They sold the tooling to TA, who modified it some, and, voila, it was an SPX!

 

I think use the TA if it fits under your hood. There better, but bigger. Otherwise the edelbrock is ok.

 

Does the Sp-1 not fit under the hood of 70-72 Larks? I've seen lotta guys running them, but some on this Board say they won't work w/o hood scoop. What's up?

Do you think either Edelbrock manifold is significantly better than the S-Divider?

AKA if I spent the money and switched....would I feel any difference?

I've got a 67 with barely any hood clearance and don't think I could wedge in an SP1...
