when i got my 94'chevy 5.7 truckmotor the guy threw in a compcam #12-238-2 and i thought it wasnt gonna work with computer controlled and i wasnt sure it would work with a non roller motor....

for any more info check the sig
thanx
this what compcam said:

The #12-238-2 will not work with fuel injection. With a TBI setup you
will need #12-249-4. This will work for theTPI also, but you can go with a
bigger cam with the TPI without going to a chip. Here are the specs below.
Thank you,

is this a good choice for the truck motor to give a little more power and idea on what the idle will be like??? ive got to get cam like now, so im gonna start calling around, just want your guys input b4 i buy
could i go bigger than #12-249-4....94' chevy 5.7 truck motor L05 non roller
will be upgrading to the 9c1 caprice chip and bigger injectors, knock sensors

that is a very small cam. it would prolly work very well with tbi, but if you are gonna go through teh trouble of a cam swap i woudl suggest being a bit more aggressive. check out about 2 steps up the extreme energy line, zz4, and LT4 hot cam kit. these will all get you a lot more bang for your efforts once they are tuned in.

later

ive already got the cam out of the motor....the lifters were bad when i pulled the the intake off to check the wear and tear on the motor...im doing an engine overhaul on it...so ive already got the motor on a stand and the stock cam has some minor wear and tear, so all have to do is throw another cam in there. but the motor is not have a roller cam...so doesnt that mean the lt1, lt4 cams roller....i also only have 2 bux to spend on a new cam
