I have a 88 350 TPI im going to carb. I know I want a 650 speed demon but I dont know what intake manifold,my car has stock heads.mild cam not sure of the duration probably around 222 or so,hooker super comp headers,t h 400 trans 3.45 gear rear.I know I want an 87 up bolt angle manifold. any suggestions would be appriacated.

 

Your choices are very limited. Edelbrock Performer or Weiand Action+. Of the two, I'd choose the Weiand.

Or, you could not worry about the bolt angles and get a manifold that matches your cam. Of course, that would require knowing exactly what your cam is. Then, after you have the proper manifold in hand, you elongate the center two manifold mount bolt holes on each side and bolt it to your heads.

 

I got the holley street dominator intake. It has 87+ bolt pattern.

Supposedly it has a idle-7200 rpm range. They have this manifold in a short version and a tall version mine is the tall version. It is a nice manifold. I really like it. Its pretty tall....about as tall as a edelbrock RPM I think.

"Idle-5500 RPM power band"

 

Looks like they also have a square-bore version, idle-6000 w/EGR. Why would they have a square-bore EGR version, but not a q-jet EGR version?????

This is the part number I have 510-300-70

Idle-7200 rpm, Dual Plane, 1987-up with Cast Iron Heads

It is a taller version of that idle-5500rpm one. We carry both at work and the only difference I saw was the height. The one I have is over an inch taller than the short one.

510-300-70
Idle-7200 rpm, Dual Plane, 1987-up with Cast Iron Heads
Dual plane design is 1.25'' taller than stock for increased fuel velocity. Square Holley flanged with provision for alternator and A/C brackets. Will not work with Dart Iron Eagle or Dart Pro-1 heads.
Features:

Idle-7200 RPM power band.
High rise/dual plane design.
No EGR provision.
Square flange carburetor mounting.

Jeg's part number.

 

Thanks for everyones help, I believe I am going wirh the holley street dominator with idle to 7200. I did not like the way the edelbrock sounded and could not get much info on the wieland

 

The holley is nice. Looks good and performs well. Its pretty tall but with a dropbase and a 3'' element it fit under my stock hood with my holley carb.
