3.4c mods?? Want lots of N/A power

Can i use the dremel on my block?

Yeah, but there's a LOT of stuff to remove. I used an air grinder.

Using a cam gear puller on the 94-97 cogs will just break the cogs. The cogs should just fall off when you remove the cone locks. You can't really use a puller on the locks.

I was talking about the 91-93 cam gears. Those are the ones I have done the most, so that was the first thing to pop into my mind. My 92 has the 94-97 gears, and so does my project engine in the garage (95) so I no longer have to worry about those stupid lock rings anymore.

if you have a little extra $$$, blueprint the oil pump.

If your shop has a machine, shot peen the block when you're done removing all the casting flash and smoothing out oil drainback passages, before you have it bored and honed. My machinist shot peened my block and it turned out very nice. All of the rough casting finish is smoothed down and there are no longer any sharp edges anywhere.
Be wary of knife edging the crank. You can possibly remove too much material, to the point that it can't be balanced. Consult your machine shop.

What exactly is shot peening?

What exactly is shot peening?

You might want to look that up before you say you're going to get your rods shot peened :-)


The shot peening process for the block would be different than the rods; it doesn't necessarily need to be done with the same amount of force and consistency on the block as the rods. My shop had their own shot peening machine for cleaning iron blocks and stuff. I think it was more along the lines of a shot blaster but it did take down rough peaks on the casting and whatnot.
