Hey guys I have a 89 formula TBI car with a 355, My engine builder installed a LITTLE BITTY cam its like 414 lift 210@50, but my boss has a cam from his LT1, will this cam work in my car? If so will my Z28 valve springs work for this cam? Will I have to get a custom chip burned for the cam or will stock one work? Does anyone know what the specs are on the cam, it come from a 96 z28? Sorry about all the questions and thanks for the help.


Just made my intake to fit a 454 TBI and found some 65psi cop car injectors, this will be installed tomarrow, Hope it works

 

An LT1 cam would be pretty lame IMHO for a 355.

Actually your cam has more duration (read higher RPM HP) than the LT1 cam.

Here's a chart that Vader posts here quite a lot. I must say though that the cam I have (LT1 cam) isn't on this list.

The only way to tell for sure what you have is to break out with the dial caliper and/or a dial indicator as well as a degree wheel.

BTW, I spec'd mine. It's out of a '96 also. It reads as follows...
LSA - 116
Int - .450"
Exh - .459"
Int dur @ .050" - 203*
Exh dur @ .050" - 208*

As you see it has more lift than yours, but not quite as much duration, which is atypical of a roller cam.

 

well my cam took a dump, and I have a LT1 cam, will it work and what do I have to change?

 

I would do a search in the TBI board for

LT1

or

LT1 Cam

or

LT1 Cam Install

You're sure to get some results.

 

yes it will work no problem. since you have a roller motor it will work. take the old one out and slap the new one in.

 

Make sure to tap the dowel pin in so that it only sticks out .300"...
