I purchased a Dart 4.00 bore Aluminum block to have an open track/ street motor built for my FIA.

331
10:1
7000 rpm
Solid Roller
Weber 48 IDA
AFR 195 Heads
Jesel Valve Train
Eagle Forged Lower

I took a look at the specs for the Inglese Weber cams and have spoken to Comp Cams about grinding a solid roller for the Webers. The tech said they were unable to reproduce the hydraulic spec for the solid as he uses a different cook book to build solids.

He wants to use the XR280 as the basis for the new cam.

242-248 0.608-0.614 115°

For comparison => Inglese Stage 2

222-224 0.571-0.565 115°

Is the increased duration and lift of any concern with respect to the Webers?
