Weight might be a little more as I'm going back to my steel hood next spring. May look at pulling some weight in other ways if I have time, but after sitting out last summer being crew chef only for my wife's car, I need mine back. 8345162-NCM_0309.JPG (63 downloads) www.dunnuckracing.com

Dunnuck Racing OP master Joined: Mar 2007 Posts: 3,300 Northern Indiana	Ian, thanks and I know you build some pretty mean small blocks on your side of the pond also!! As far as Crane rockers go, I have used a few sets on builds over the years with no issues other than one set that had bad adjusters. I have used Hughes rockers recently and like those too. I'm not a big believer in roller bearings in a stock sized shaft rocker. I have a set of Crane Golds in my wife's 440 that have been beat on in for at least 15 years. The wear area is still like New on the rocker/ shaft area. Keith www.dunnuckracing.com

I'm going to freshen my 408 this winter and am planning on bumping my compression from 10.9 to 11.4 or 5. My heads are milled to 55cc's and my pistons have either 20 or 22cc dish. So I'm planning dropping the dish to 15 or 16cc's to get the compression up. I'll keep the cam, a Hughes flat solid 260/264 @ .050, .628/.633 lift with 1.6 rockers. Nice build BTW.

Dunnuck Racing OP master Joined: Mar 2007 Posts: 3,300 Northern Indiana	With the 4.125 stroke and a flat top at zero deck, compression is a little higher than I would want for pump gas using an RPM heads normal chambers. I took mine out from 63.5 to 68 cc. It worked out well with the way I wanted to shape the chambers. And Dave, I like the 4.125 stroke over the 4.00 inch mainly for the lighter putting. The extra stroke causes no issues with skirt and bore wear if its built correctly. And the torque can be pretty nice! Keith www.dunnuckracing.com

I run the same heads as you except Edelbrock magnums - Hughes ported with almost identical flow #'s - per Hughes. Been running Hughes 1.6 rockers going on 5 years now with no problems. Fastest 300
