i really dont know what size stock cam is so let me ask a question will a 447 lift and 222 duration cam work with out doing any changes to the compter all ive done to my motor is 52mm tb ported and polished runners and plem

 

All cam lift specs are with 1.5RR unless noted.

1985-1986:
Duration @ 0.050 202/206
Lift with 1.5 R 403/415
Lobe Seperation 114.5

CAM 87 L98 14093643 Dur In/Exh 294'/294' Dur@.050" 202'/206' Lift (w/1.5) .403"/.415" LobSep 114.5'
CAM 88-89 L98 10066049 In/Exh Dur@.050" 207'/213' Lift (w/1.5) .415"/.430" LobSep 117'
CAM 90-91 L98 10111773 In/Exh Dur@.050" 202'/207' Lift (w/1.5) .413"/.428" LobSep 114.5'

92 LT1 205/207 @ 0.050" .451"/.450" Lift, LSA 117
93-95 LT1 202/207 @ 0.050" .450"/.460" Lift, LSA 116

96 LT4 203/210 @ 0.050" .475"/.479" LSA 115

Popular aftermarket cams that are typically recommended on the forum:

ZZ4 camshaft-this is the cam which comes with the ZZ4 crate motor sold by Chevrolet.
ZZ4-208/221 @.050" .474/.510

Accel cams: Bear in mind that now ACCEL cams are ground by CompCams, and their specs HAVE changed over the last few years on the lift.

74211:
211/219 @050", Lift-.530/.560 w/1.6 112 LSA
Designed for use with modified TPI systems.

74219:
219/219 @050", Lift-.560/.560 w/1.6 112 LSA
Superram camshaft

One that is not recommended often is the 216, also for modified TPI systems, that does not require valve guide machining.
216/219 @050", Lift-.493/.502 w/1.6 112 LSA

Hyd flat tappet versions are the 212 and 213.
212 is equivalent to the 211 or 216, and the 213 is intended for SR use.
212-214/224 @050", .443/.465, 112 LSA
213-224/234 @050", .465/.488, 112 LSA
(these two cams may not be made and sold as Accel any longer)

Supercharger use:
74220-215/220 @.050" .534/.544 w/1.6 112 LSA

TPiS cams:
ZZ9-
212/226 @050", .483/.520, 112 LSA
Designed for use with Modified TPI, or a basic Miniram cam.

ZZ-409-
226/226 @050", .520/.520, 112 LSA
Best with Miniram, this is the smallest TPiS cam I would go with if I were to pick MR. Camshaft recommendations for MR follow the LT1 cams below, since they are basically the same manifold.

LT1 cams:
LT4 Hotcam
219/228 @050", Lift-.525/.525 w/1.6RR, 112 LSA
(Lift is .492/.492 w/ 1.5RR)

Technical Notes: The LT4 camshaft P/N 24502586 was designed to be used
in a number of different engines. Therefore, the following change may
need to be made to allow for correct assembly of the engine: For LT1
and L98 engines 1995 and before, the dowel pin in the end of the
camshaft must be pushed in so extension from end of cam is .30+/-.01",
the same as the production part. For 1996 LT1 and LT4 engines, the
dowel pin is in the correct position, extending .620" from the end of
the camshaft. This camshaft has a fuel pump lobe.


Comp Cam 305
220/230 @050", .510/.510, 114 lSA

Comp Cam 306
230/244 @050", .510/.540, 112 LSA

 

 

If you're running it on a 57 Chevy, no computer changes required. Computer changes probably would make it run "better" if you're putting in some year/type of Corvette.

MAFs run better than SD setup's w/o making changes. That's not to say neither or both would "work",,,or what your definition of "work" really is.
