    Would the 308s work with a .038 over approximately 11.5-1 455, slightly better flowing ta stg 1 heads, th400, 3800 stall and 3.73 gears 29.5 tall tire? Have this cam from a motor I blew up but would consider any better Cam for this combo. Thoughts? Thanks.

    Thats is a great cam for that application as long as you are not needing vacuum for power brakes. I think my 308s with iron heads at 900rpn only had like 5 or 6" on the gauge.....

    Thanks for the input. I was second guessing using this cam. Don’t need vacuum, no street use.

    Yeah, that would be a runner. Be pretty close to needing Race Gas, but might run on 93.

    Make a video when you stab it in. Would like to hear it.

    Would a vacuum can be enough with this cam or would a pump be better for a street/strip car? I've been thinking about a similar build except with stage 2 heads.
    Thanks,

    I would think you would be better with a pump. I think you need 12"-13" manual to keep brakes happy.........so you might get there off a full throttle decel.......but not driving around town

    I've ran non power disc brakes on the car for the last 20 years. When the engine let go about 2 years ago I put together a mostly stockish 455 with parts I had laying around until I can build something else. I also put the power brake booster back on and I think I want to keep it. I'm still figuring out how far I want to go with the next engine but I plan on starting on it this year. Thanks for your input.
