    bbc

    It should make 700HP no problem.
    I would suggest a solid roller cam "around" .713 lift intake and exhaust
    and 265/275 @.050 Duration.I would like to see a little more intake runner volume than 315. AFR's are nice and it will be a street motor,but 540's (cid) seem to like 345. Some folks on this forum have more experience than I do and they may have better suggestions. You will make 700 HP .I had a 12.4 to 1 dart headed (345's) out of the box- 496 BBC. in my case the intake runners were a little big, but I had the heads they were new and they would work well if I decided to spray it.It made over 700 hp Similar cam specs
    Good Luck
    Also the cam companies out there will give you advise and RJ has some very smart people that may help also

    Thanx, yours seems a little closer than what I got from the cam compamies, lets see what others think.........

    and the 315 head flows a bit better at .400 lift than the 335 head

    cam rec?

    i would suggest a lift that is compatible with your valvesprings :lol: what are they good for?

    like your intake runner volume at 315cc, good choice..

    also like the recommendation 265/275 degrees at .050", nice..not sure on sep, maybe 110 or 112 degrees..

    how are we doing

    BBC carb suggestion

    If you have the luxury, try the 1050 dominator.Maybe even the HP. They seem to work well on the street and the track. I even had an older 2 circuit nas car style 1050 and it never gimped or had a hesitation or transition problem, it was on 2 bbc's. A 10 to 1 489 roller motor with steel heads, and the 496. 12 to 1 alum headed 700 Hp BBC dynoed and the air fuel ratio,s were good. And alot of street driving JMO

    I've never had a 4500 stall for the street. I'm sure the other guys could give some advice on that.
    The 11-773-8 would be good, but you may also want to look at the 11-772-810. Depends on weather you want a little more street or strip.

    MECHANICAL ROLLER − Good in weekend
    warrior with 3000+ stall. Needs good
    intake and exhaust with low gears.
    3000 to 7000 11-772-8, 286 292 248 254 .653 .660 110

    MECHANICAL ROLLER − Best for Pro
    Street. Needs good intake and exhaust,
    11:1+ compression and 3500+ stall.
    3200 to 7200
    11-773-8 292 298 254 260 .660 .666 110

    Either way It's gonna be a nice motor in a street car!!
