The lifter bores would need to be shortened by about 0.200 and then this approach would work. The spider will work just fine once the dogbones were in place.

If you don't own a multi-axis machining center then it isn't really a drop-in operation. That is the tough thing about answering a question like this. To a guy like Ryan these things just bolt together! To the average guy with a Craftsman tool box and a double car garage it just isn't possible.

I dialed in the cam even though I'm not sure I'll be able to use it. Comp is sending me some new lifters that haven't been announced yet that are supposed to work in this 340 resto block. If they don't work then the roller stuff is all going back on the shelf and I'll run a solid flat tappet cam. 5771227-progear.jpg (121 downloads)

The link bar is attached to the front side of the link bar support on the body which is far away from the side of the valley sides. I have the lifters and I have a resto block and they work great. Brian at IMM helped out on the design of those lifters before Comp even had a part number. Nice stuff. 10.53 @ 125mph. 1.37 60 foot. Caltracs and Monoleafs, AFCO shocks.

I use steel fittings for an application like this but some people might use aluminum. Anyplace that handles hydraulic hoses should be able to get you the fittings.

The inner head bolt bosses have been machined off and the valley has gotten some work with a sanding roll to smooth it out. According to the sonic checker the valley wall is still about 0.200 thick. 5788616-8043cl.jpg (157 downloads)

I had already cleaned up the top of the lifter bosses when I had the block in the fixture. I'm glad I did that or else these might not have cleared. 5788617-8043tie.jpg (126 downloads)

Many of the lifter mfgs drill from the bottom which doesn't work. Not sure why some folks continue to build parts for 30 years that don't work but they do. There is also a small EDM hole that feeds the roller. It is too small to see but it comes in off of the relief area so it should get full oil pressure all the time. I haven't measured yet to see how much lift these can handle before exposing the oil gallery but I think it is probably a bunch. 5788629-8043.jpg (137 downloads)
