HELP! 2.8 or 3.1 block

[Superdave]

What side of the block is drilled/tapped for a starter?





~86 and earlier FWD blocks probably didn't have the CPS hole drilled, 87-94 would. If it's a RWD block then 82-92 would all basically be the same and not have the hole drilled. If it's a RWD block it won't work in you application. The mounting bosses are quite different. There isn't much dish to those pistons either, they look like they're for an iron head application.

Here are some more gen 2 FWD block pictures to help..

Forgot to add that it might be a 2.8l from a early FWD x-body or J-body like the Cadillac Cimarron. You might wanto check if it has a fuel pump hole on the block. If so you need to ditch that engine and sell it. Cheaper to find another aluminum head engine when it's all said and done.

You could probably use an external crank trigger if you can't drill the block.

You'd have a hard time drilling the hole being g square and then keeping the sensor air gap . I assume that crank has no tone ring for the sensor and you wanto use your crank. You'll have to check if that is a small journal crank and if its not you can use yours and have to rebalance the rotating assymbly.

I bought a short block awhile back that i think was bored .020 over (have not measured yet)for my 91 beretta.I finally got a set of heads ready and unwrapped the short block to find out it does not have the crank sensor hole drilled out in the block.Has any one ever drilled out a block for the sensor? Has the threaded hole beside it.Also could i use the crank shaft from my motor that has the sensor pick up notches on it? PLEASE ANY HELP!
