hey guys i am looking at tbi intakes and from what i can see. there is only 3.
the edelbrock,the holley and the gmpp.
i am wondering if anybody has flow numbers on them ?
qnd is there alot of difference between the 454 T.B and the holley T.B. ?

thanks guys

 

the reason i am wondering about the intakes and T.B. is i am thinking about building 400 sbc. with a set of tpi or vortec heads(not sure witch way to go yet ). and i just wanted to know if any of these aftermarket intakes where better then the stockers.
not looking for monster power here just somthing that works great.

thanks

 

carb intakes are also a popular choice, ofc u need the adapter.

 

Carb intake manifold and an adapter plate for the TBI would be cheaper and, IMO, better than a TBI intake.

 

i kinnda don't want to go that way. i want to stay tbi specific. and was just wondering if any of these intakes where better then the stock ones.
as for T.B 's should i get a holley or a 454 or should i just bore my stock one ??

 

the edelbrock is better than stock. I'm guessing your running a 305 bored .030? The stock tb will do the job. Unless your going with bigger heads and large cam.

 

well i am looking in to building a 400 sbc with tpi heads or vortec heads

 

Have you done a search here?
There is not a ton of data (especially on the Holley), but you will find some if you search for it.

 

i did read alot of posts.theres alot of info here thats for sure!

 

well i think i will go with the holley intake . can sombody tell me the difference between. the 300-66 and the 300-49 ??
i read up all the description on jegs and sumit and on the holley site and cant see any difference?

thanks guys!

 

On Holley site it specifies the model year. -49 for 1962-1986 or 1987 with alum heads. -66 for 1987- later cast iron heads. I run that Holley. Another option is a weiand single plane Accellerator(low profile) with TBI adapter plate. Vortec may require a carb manifold due to cost factor.

 

hey thanks man i must have mist that part .i looked on summit&jegs and the description was the same. so thanks for clearing that up man.
