you cant not enough piston to valve clearnce. you can use a e,b or f 303 cam though

You will have to have your pistons flycut for clearance. You will also need to replace/upgrade your valvesprings. I will tell you this, if you are running stock or small aftermarket replacement heads, and a stock or smaller aftermarket intake, this cam is worthless to you, and you will be better with likely an E cam. E cams are good with 5 speed cars, and HAve a good powerband for a stockish motor. I am running Trick Flow Twisted Wedge Heads, a Holley Systemax Intake, and the X Cam. For my setup it is very good.

why is it worthless


what is the biggest cam i can use and how what is the biggest b or f

Mustangkiler

because you will have no lower end, the cam wouldnt match the airflow your getting from everything else and you would be going nowhere until like 3500 rpm, now if you build everything else up too then ya itd be a good one for ya

Mustangkiler

id stick with b or e, for now thatd be plenty

ih8chevy

i should say that this cam would be going into a block with afr heads shouldi stick wit a e or b

I'll agree with the others here. Unless you upgrade your heads, you're going to see very minimal gains from any cam upgrade and, with the 86, your pistons will need to be notched or replaced for valve clearance.

what year is it? someone said 86 and in that case you definetly dont want to go anywhere near an x-cam w/o a maf conversion
