stroking a 4 cyl Options

[ws91420]

Looking to build a 2270. I know I know get a Jake kit.
I'm a bit of a rebel and want to go at it myself.
Stroker crank 78mm what else is needed.

is a longer cylinder need for the stroke
longer rods should I go chevy or type 4 rod journals
thinking about doing larger intake valves on the heads and using 40mm Webers

I guess the thing is that I have a fairly fresh rebuild of a 2.0 in the car that I want to use. Heads had new valve guides and one seat replaced and the others checked. new valves put in. A high volume melling oil pump was put in as well. I did not put a cam for carbs in b/c at the time I was planning to stay w/ FI. I already have carbs 40 mm Webers so I would like to stay with them at this time.
I did the rebuild before I ever heard of Jake and his stuff and before he started offering kits.

The thing to do would be to sell the fresh 2.0 for good money and find another engine as a core. For the core all you need to send Jake is a 2L crank, 914 flywheel, and 914 fan. You can even start with a 1.7 or 1.8 core since it's easy enough to buy a 2L crank for $150-200.

As Aaron said, to make good power out of a 2270 you need high performance heads. At minimum you need a high performance valve train to match the cam.
