Well, since I replaced my stock 346 with a forged 347, I have been considering whether or not to sleeve the old block. I am wanting to not go max bore on a resleeve, kind of leaves me no room for rebuild later, and another weird thing, I want to keep stock crank, yes stock stroke. Why? Not really sure, other than I'd like to assemble it, run it and then maybe later do a stroker crank etc.. I tend to use nitrous, as much as I try not to it happens

So the extra torque from a stroker really is not that big a deal to me. The extra rev's from a big-bore I prefer, for now.
Reading through pages of Darton sleeve literature, I see Evans pump and coolant is recommended. Are the sleeved guys really using this stuff?
Thanks.
