I got a 212 build I want to do, but would like to hear some seasoned veteran's advice since I don't have as much experience as you do

Not allowed to get a job? We really are living in a communist state.

I know right

You are correct. They don't make champion rockers for the hemi. Your stock hemi rockers are stronger than the non-hemi rockers.
All the parts you don't have are the expensive ones. Suggestion. Buy everything
EXCEPT for the stroker crank. You do have the stock one, don't you? It will cost less, go together much easier, and a good running hopped up 212 will put a big smile on your face. A shopping cart? You might want to rethink that part also.

the plan was to have a shopping cart welded to a chassis I was going to make, then reinforce it by welding a bit of sheet metal since I can do that at school. Doyou really think It will hold up to 48lb dual springs? Also I do have stock non hemi

I always imagine some sort of human-shopping cart hybrid, mangled mess, whenever I hear about the "shopping cart" karts. Scares the hell out of me to think about it. -But then again, they ARE made for public use so they could probably withstand a nuclear bomb.

The first 'shopping cart' kart I had ever heard of was this guy. He has several videos on it if anyone is interested.

I have no idea if they will hold up to 48lb. springs. Have you already purchased the springs and the NR racing cylinder head? On all of my small block builds, I use either 26 lb or on one engine ( my very hottest ) I run 36 lb duals. I don't see a need for so much spring pressure. Also FYI, when people build these engines, and start getting into high compression ratios and high lift cams ( either by the cam itself or by the use of ratio rockers ) they always get rid of the hemi head and go to the conventional wedge head. Reason being with the valves in the hemi sitting on an angle, piston to valve clearance becomes an problem right away. You can run a lot more lift ( watch out for coil bind ) with the regular head then with the hemi.

yes I have bought those parts, I have that hemi head because a guy sold me a bunch of parts for 150

Question for you: If you have a stock, running non hemi 212 and no frame to put it on, why not look for a frame to put the 212 on and run it?
You can modify it as you learn and acquire parts (maybe after you get a job...) but you can ride your cart as you gain skills?

 

[panchothedog]

Do you currently own a predator engine? Or do you just have the head and springs? If you do currently own a predator engine, which one is it. Meaning what configuration is the stock cylinder head. Hemi, or non hemi.

thing is I have it on a manco vortex fox right now

I have one a stock non hemi that I have on a manco vortex, and I have an empty block that I was planning on putting the hemi head on.

 

[panchothedog]

Do you know if the empty block you have was originally a hemi or not? The reason being that the cam journal ( the shaft ) are different sizes and are not interchangeable. The bore in the block and the side cover are different between the two engines.

its a Hemi block with hemi side cover

In the meantime, my uncle has a 1975 or 1974 Honda ct70 that he has all the parts for me to fix it up. That will keep me busy in the meantime while I save up, and also driving my stock manco vortex around.

Honda CT70s are great little machines. I’ve had over a dozen when I was a kid!!!!
