the mini-express with mushroom tappets
Yes the MP Mushroom cam and Lifter .690 lift
With Speed Pro 11.5 (Boat Anchor - Heavy) pistons
on Sunoco 97 or Shell 95.5 gas
There are actually two Mini-Express mushroom cams, the 316 duration (278 @ .050) with .654 gross lift, and the bigger one 328 adv. (don't know the .050) with .690 lift. My '82 D.C. book says the .690 "loses some low speed torque"...
I built my 451 around the smaller one. Reground to restore lobe taper and now .652 and 272 @ .050. Has a really nasty idle, 6-7" Hg at 1000-1100 rpm. Should be fun once I get the A-body reassembled this fall
