CAM

[hetrickw]

I'm currently replacing timing set and damper (balancer), and wanted to try and replace cam & lifters, while I'm in it. Don't know crap about cams but can install one. The block id is D4AE-6015-AA2 and was rebuilt back in 1985. Its a 28 Apr 1975 block. I know the firing order is for a 302 ( 1,5,4,2,6,3,7,8) because I've worked on that motor for 30 years. I didn't rebuild the motor, so I don't know what cam they put in. I need to know what my cam options are? Should I buy a 302 cam or 351w cam or are they both the same? I'm running stock engine, with edelbrock intake and Holley 650 , headman headders, just like high school in seventies. like a little more punch... but don't want to spend too much $....thanks for your help.

if you want quicker acceleration, imo your best bet is to install numerically higher gears.

if you want a cam then i would suggest a comp xe256h with crane lifters if your gears are 3.00 or numerically lower . . this cam pulls right off the bottom and idles smooth but doesn't rev far.

also, i would buy a set of optional secondary springs and try the white one . . if it bogs when you floor it, install one that is 2 steps heavier.

set your gas level to just below the inspection windows with the engine idling.

also, that carb is a bit big for your app . . you can install a screw with a nut on the back side of the secondary opening arm at the rear of the slot . . this will reduce how far they can open which will reduce the total cfm of the carb slightly.

I'm still trying to decide to put cam in and pull intake replace lifters.

i'm running a edelbrock torker II 351w intake. I guess if I do decide to do the cam now, I am wondering what are the best type of LIFTERS to get, I know how to replace them but, don't know much about the different types, hydraulic, solic, etc... and will I have to replace the rods? i'm looking for a little more punch, but not too much adjustment/time spent inside the heads adjusting rockers etc.........

any assistance is appreciated.........

i use crane lifters . . comp lifters are not very good.

you can use the same push rods . . you can also set your valve train geometry if you want but you may need new lifters if you do that.
