B&M Mega charger cam shaft specs

New kid on the block here was searching the web for info on the B&M mega blower and ran across some post in this site about the cam shaft specs..I have this cam installed in my 350 engine 76 vette with the mega blower..It is SCARRY..I am also posting a copy of the original spec card from B&M that came with the cam..I also run RHODES VARIABLE DURATION LIFTERS in this engine with this cam..and have been well pleased with this comb..No issues..The grind number in the top left corner is 90753..Hope this helps someone..

I'm not very good at picking cams but that one seems way long for a blower.

Thanks, that looks pretty typical for blower, turbo, nitrous cams. The big issue that boosting regardles of method brings is getting rid of the increased amount of exhaust, so seeing more duration and lift is what is needed which is what this cam presents.

This is useful and practical information a builder of such an engine needs to have.

Would love to see some numbers from that cam. That cam looks like it's meant for a build that consists of 'compression in the tank, mileage isn't a concern and let the boost do the work'.

I'd guess 600-700 whp at 14 psi if the short block can take it.

Edit : forgot to mention - close to 7K rpm's
