Smallish roller cam for DD 318LA

Your question, illustrates that you dont really know much about 318's, or cylinder heads in general.

You want to increase the power of your existing 318...

You want some lope, and some more mid range, and a little more top end power.

You didnt state any specifics about the EXACT 318 you have....what other modifications, you already have, and you stated you dont want to break the bank.

If you did some SEARCH'ing with the SEARCH button.....or did some READING....of the STICKY's that are along the top of each forum....You would know, that we (all us Experienced A-Body Owners) are more than willing to help others out with advice, and our experience.....but you really need to give us more information RIGHT OFF THE BAT, and maybe mention that you realize modifications cost money, and ask...."what would I be looking at to accomplish this upgrade properly?"

stock 318 1.78/1.50 valve heads with econo NON-performance ports/springs would hardly benefit from a cam and lifter swap....without modifications to the heads themselves...IE, changing valve springs, seals, gasket matching..ect.

Spend the DOLLARS where it matters if your on a budget....


It goes like this...
Exhaust pipe diameter increase from 2" to dual 2.5"
Ignition
Headers
Intake and carburetor
TIRES
CYLINDER HEADS
Camshaft and Lifters
then Progressively more...

You cant take a stock 318.....throw a 292* .509" 108 in it with stock valve springs, a set of CL headers, an Edelbrock Carb and Performer intake and bruise the streets.....well I guess you could....till the pistons hit the valves.

For all your Roller Cam 318/360 needs....
