170ci to 210ci stroker

VNTNED, I am getting ready to build the same engine. Looking for a 170 block now close to Washington which wont cost an arm and a leg to ship. I am looking at purchasing a 69 Barracuda which will be the home of the 210 slant six I plan on building.

I have built power out of a NON Turbo'd 225 Slant Six when I worked at a engine machine shop. Ended up with a 13.9 second quarter mile behind a 3.90 gear ratio (jeep Cherokee gears) Chry 8.25 limited slip rear end and a manual 3sp.

The biggest reason for considering the 210 build is the slightly shorter stroke over the 225. While my 225 could rev higher than stock. A shorter stroke would allow for higher rev limit given you invest well in balancing.

If your open to suggestions, may want to consider the MegaSquirt option if you want to pull real power out of the slant six. Look at what Jeep does with the 4.0L (242). An that is BATCH fire fuel injection as late as 2000. If memory serves me correctly, MegaSquirt 2 an 3 can be setup sequential or batch fire.

Mopar Performance allows you to buy a Jeep 4.0 fuel injection controller with wiring harness for the H.O. era jeeps for about $500. An its meant to be used on any inline 6 which you plan on batch firing the fuel injection. Uses a Chevy MAP sensor. Pretty simple to trigger, just add crank trigger an the ECU controls the timing. Hardest part is getting the machine work done (to install the injector bungs) on the intake manifold if you don't just buy a custom one such as if you want to mod a hyper-6 manifold.

I look forward to watching what you end up going with.
