monte70car Posted April 13, 2011 Share Posted April 13, 2011 I'm thinking it's time to get raid of the old Blazer series cam that's been living my big block since 96. I don't have any specs on the Blazer cam so it makes it hard to pick a replacement. I'm working with a 67 396(325hp) block that's 40 over stock with a set of 68-69 396 (325hp) heads it was supposed to be a stock rebuild. I did pick out 4 cams which I think would work for a street cruiser. comp cam xtreme CL11-230-3, voodoo 60200LK, comp cam magnum CL11-207-3, voodoo 60202LK Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted April 13, 2011 Share Posted April 13, 2011 more info... rear gear torque conv stall I guess since it's a stock rebuild we'll call it 10.25:1 compression? Quote Link to comment Share on other sites More sharing options...
monte70car Posted April 13, 2011 Author Share Posted April 13, 2011 Rear gear is 2.73 stall is 2200. Sam that's the compression I've been playing with I can tell you that the intake was shaved 10 thousands to fit the motor. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted April 13, 2011 Share Posted April 13, 2011 With the gear, stall, and fuel injection that you are working with I would talk to the fuel injection supplier and cam manufacturers I am thinking mild. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted April 13, 2011 Share Posted April 13, 2011 Hmmmm....the intake had to be cut down too??? your compression could be even higher which is pushing you near needing race fuel. if!!! this is the case, I would consider one of Comps thumper cams to bleed off some compression, I really like the one I got from Davey, nasty idle, pulls good past 5000 RPM, I think it's 11-600-8, but it's a hydraulic roller, and your conv fits it too (2000rpm +) Quote Link to comment Share on other sites More sharing options...
wallaby Posted April 13, 2011 Share Posted April 13, 2011 I don't think Comp's magnum series is a modern design...could be wrong, but the single patern cams are more for budget racing I think. I started with a Comp 268XE, but it had idle issues and didn't work too well with the power brakes, (and I had issues of valve springs breaking) so I changed it out for the Voodoo 60202. The Voodoo worked better for me; it has a pretty smooth idle, pulls nice vacuum, and makes more bottom end torque...but Sam has a point; this cam makes strong torque with a high lift and short duration, which results in high cylinder pressures. If your engine isn't too high in compression and pinging isn't a problem, the engine will love it. Quote Link to comment Share on other sites More sharing options...
cudax Posted April 14, 2011 Share Posted April 14, 2011 Anyone ever try these guys? http://bulletcams.com/ Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted April 14, 2011 Share Posted April 14, 2011 I use Chris Straub, his designs are ground by Bullet, Bullet has some great designs also. I think Ert needs to work within the parameters of his fuel injection unit. Quote Link to comment Share on other sites More sharing options...
