What about 318 stroker kits?
I seem to be all over the map as I decide what to do with my stock 318 72 cuda rebuild.
So far I acquired a set of 69 340 X cyl hd castings.
As I learn more about it, it is not a good move for a small 318.
Then I thought to get a 340 block and rebuild, but found out 360 will give me more for far less and easier to find.
Now I am thinking about 318 stroker kits in addition to boring 0.040".
I like that there are kits that you can dial in your CR with diff pistons.
I also like that I can really bump up the displacement to better utilize those big 2.02" valves.
Anyone do something similar?
Any wisdom shared wud b great.

What kind of power are you looking to get out of the motor?
The 318 is a good platform as long as you are realistic.
like they say there is no replacement for displacement. so in that sense bigger is better if lots of power is what you are looking for.
i think it is procharger that makes a centrifigul supercharger that will work with a 318, you could play with that idea if you really want to get creative.
I just rebuilt a 318, i used stock 67 318 head with the hardened valve seats, ported the heads a little, KB Forged not cast pistons to get the compression up to 9.6-1 with electronic ignition, edelbrock intake and 600 cfm carb and other than a couple little probelms here and there the thing runs great, and has good power through the whole RPM range
Its no drag car but fun to drive.
not sure if that helps at all

what kind of hp are you at?
I only want to do something with the lame stock 150hp.
I would be happy at 300 and real happy at 350.
Low end torque is nice too, but I want a little top end as well.

I am not sure what HP i am at now i have not dyno tested it yet. i would guess i am at high 200's at the rear wheel. enough to burn the tires and scare the wife from time to time.
if you want the 300 number at the rear wheel i would go with the bigger engine. You can get that out of a 318 but you will have to do more work to the engine.
I like the 318 motor though , it is a strong motor that will last a long time and the crank is forged, as long as you get the compression up you can get good power,
I would go talk with your local machine shop. those are the guys that helped me build my motor. Those guys know where to grab the HP from when building a motor.
Hope that helps
