Has anyone ever taken the dowel pins out of the back of a Chevy V8 block?
I have to remove mine to install offset adjustable ones to index a blowproof bellhousing. Lakewood says a pair of Vise Grips or a drift punch and hammer.
My engine is still in the car but I can remove the headers and a few other things to be able to get to the pins from the front I think.
Anyone been there,done that ???????
Thanks , Gene

Yes, drove them out from the front, they usually aren't that tight a press fit.

Eric, did you do your dowel pins in the car or out and big block or small block? Mine is a 69 Chevelle with a big block, I think I may be able to do the passengers side from the front with a long drift punch its a pretty straight shot but the drivers dowel from the front is blocked by the boss for the clutch pivot ball and threaded boss for the oil pressure fittings.
May end up taking the engine out or making some kind of puller to pull it out from the back ???????????????

Big Block, hanging on the engine crane, dialed the bell before we put it in the car. Had to get at the drivers side at an angle because of the boss, but it was years ago and my memory may be foggy about the way we did the drivers side. Most of the time it is Small Blocks anymore.

I use a 1/4" hardened steel rod 23" in length to get the drivers side dowel out from the front.

It may be better to go ahead and pull your engine, since you have to install and align offset dowels.

Easy way is to use a C clamp. Place a very short 1/2 " bolt in the hole(oppsite flywheel side) ; place a socket (just larger than the dowell) over the dowell; then tighten C clamp. Usually the eng. needs to be removed.
