My current cam is the following:

10066049* .415 .430 207 213 117.0 (116/-118


I know a lot of people run an Lt-1 cam...and what are the specs on that? How much of a difference is it from my current cam.....?
Thanks

you'll get an idea of the various spec's per company


very interesting!

 

I got a buddy that has a ZZ3 cam brand new in the wrapper for $100. Email me if interested.

 

there are a couple different lt1 cams. the one i just took out of my engine is this one:

201/208@ .050 .447/.459 lift ran a 13.835 @ 97.52 with it. but ihad 1.6 rockers to bring the lift up.

now i have the zz4 cam which is 208/221 @ .050 .474/.510 lift. just went 13.689 @ 99.25 with no tuning and the scanner showing lean.

i have dyno graphs here on the lt1 cam.

 

I measured the 93' Vette LT1 cam before I put it in my maro, was .456 lift, i think it's .460 stock, a little worn

 

GM .450 .450 1993 LT1 STOCK
GM .450 .460 116 LSA 1994-95 LT1 STOCK
GM .447 .459 117 LSA 1996 LT1 STOCK

 

I think that chart is incomplete.

The LT1 stock cam coming out of an F-body is slightly different than the LT1 cam from a Vette or the LT1 cam from an Impala SS/Caprice.

FYI...

 

did you run the 1.6 rockers on the stock heads without doing anything to your pushrods or pushrod holes? Reason Im asking is because im just about to do the same thing to mine..I have the LT1 cam in, 510 springs on and already have the 1.6 rockers but they are un-opened...so I can always sell them if I shouldnt do it.

I always read that the stock heads cant handle the 490 lift an LT1 gives when using 1.6 rockers
