2.0 build to 2056 or 2270?, Which cam would be best ?? Going carburetorated, with 96mm pistons Options

[zman914]

Looking to do a 2056 or 2270 build from a stock 2.0. Changing over to carburetorated, with 96mm pistons.. Looking for good cam advise. I'm looking for more hp, but very reliable.

Welcome, Zman!

Going to carbs opens up a ton of options for you. It really comes down to cost and skill. If you will be rebuilding the engine yourself and you haven't done it before, I'd probably go with a proven 2056 combination. Lots of those engines on the road with good reliability. Others can chime in with specifics. If you go up to 2270, the precision needs to be higher, so it's not something I'd attempt for my first build. You'll also need to think about supplemental oil cooling.

Either way, you'll want to make sure the case checks out as a buildable core, with registers that are dead flat and parallel to the heads. I'd also swap the galley plugs for threaded ones. Good luck!

I think you need to decide displacement before you start talking about cams. Building a big displacement type 4 today, i would run FI. That's my winter project for my 2270 motor.

The biggest difficulty for building a 2270 for a while was finding a 78.4/78mm type iv stroker crankshaft. But, currently it looks like they're available again. With aftermarket rods, you should have very little if any clearance problems with the 2270. So, the main difference between building the 2056 versus the 2270 is the size of the spacers between the case and the cylinders (and the crankshaft stroke of 71 or 78).

Pick a Webcam (with matched lifters) appropriate for the application you will be putting the motor. Or we like tool steel lifters and crower springs. With the right cam choice it'll run just fine on carbs.

We have our cam supplier (mostly Daugherty racing cams) help us with cam selection. John generally has a much better overview of the cam selection than the average builder or the home gamer.
