When set up properly the solid lifters and corresponding JWT 276 cams have no issues. No issues at idle. Less vacuum yes but nothing that we find affects drivability. If you're considering going this route, contact me and we can talk about getting you into a proper set up. We machine and modify the heads in house. Flow bench tested, dyno tested, and street proven.
In my high horsepower street car I am running solid lifters with the JWT 276 .433 cams. Mike Jackson who does all the headwork runs the same set up in his 1000+whp daily driven Z.
