    Hello all, I am in a serious debate on what cam to get for my Buick 464. the engine will have a stock crank, weisco pro tru flat top pistons, iron heads with non stage 1 valves with changing to aluminum heads in the FAR future. stock rocker arms, stage 1 valve springs with the in dampener springs taken off the exhaust valves. (Got them that way in a deal) 5/16 adjustable push rods. the objective is to make a race car that can be driven on the street. I may not beat you in a quarter mile, but I am running your ass down. Compression ratio is calculated to 10.57 to 1 abouts. (gotta run on 93 octane maybe a little octane boost) the objective is to get into the mid 500 hp with the iron heads and then break into the 600 hp when i get aluminum heads. The block is a 1973 and will have no girdle but will have billet main caps and main studs. Adding a vacuum pump is no objection (have power brakes). objective is to get the most HP.

    Cam considerations thus far
    TA 413
    TA 310
    TA 292 02h
    Comp cams thumpr & mutha thumpr

    Fire away.

    can stock connecting rods handle mid/lower 600hp or do i need TA sportsman rods?

    Is there something to gain with not running inner springs on ex valves?

    I went through the cam debate and decided to go with Scott Brown.
    He is highly reccomended and has some serious Buicks running his cams.

    I would call and give him your specs and have him do a custom grind.
    There is no way to go wrong with this option.

    Your motor is close to my build.
    Stock crank and rods. No girdle.
    464 Wiseco pistons.
    Big Port 430 heads converted to Stage 1 valves but i will be going to TA aluminum heads down the road.
    TA roller rockers.
    TA SP-1 Intake 1000cfm Holley carb
    Mallory ignition
    2" TA Headers

    Hope this helps

    not gonna hit 500hp with stock unported heads maybe 450 with a large cam that will be nothing more than peack power with not much average power them springs wont work with anythin other than a pretty mild cam

    No comments on cams i was considering? will stock connecting rods be pushed past their limits?

    I'm not anywhere near a pro on monster cammed racing engines, but I've read nothing but good from TA's 310 and 413 cams. So there's my vote. :TU:

    ...that and the 310 is about the biggest you want to go without roller rockers, or so I gather. It seems to be a well-rounded, straight pattern performance cam.

    The 413 would be the best of the ones u listed but a solid or a c 107 would be better since its not going to be daily drivet altho it wouldnt stop me from driving it daily but with the iron stock heads you gonna need a pretty good duration split and no cam sounds like a 107 window rattler stock rods will run to 6k and 600hp if prepped and the engine balance is good vehicle weight and gearing also play a roll in how much stress the rods will see also

    hugger, i have looked at the cam specs for the 413 and the c107. the 413 has a power band of 2000-6000, while the c107 has a power band of 3300-6000. wouldn't the 413 be a better cam in turns of a bigger area of a power band? what kind of stall would i need for the c107? i am thinking my max rev limit would be 6000 rpm, 5800 realistically. I am thinking of using 3.36 or 3.42 gears. hows highway driving with these cams?

    If I had to pic one of those cams I would say the 413. There are lots of guys here running in the 11's with that cam.
    Stock rods can live close to 600hp I have read. I hope so!
    When you get to the heads don't waste your money on cast iron... unless you port them yourself....Save up for aluminum

    all depends on what you wanna do with the car if you want a long legged hwy roll racer go with 3.08 to 3.23 gears with the 413 or a similar grind that doesn't require much gear and a tight verter if you want to get it done by 1320ft then go with the 107 or a similar powerband cam a cam that makes power below 3500 has no real benefit in a streetstrip app as the car will never see that rpm on the track and for only a short period on the street such a car would need a 3500 to 4000 loose stall with a 355 to 410 gear this is the type of car that will put a smile on your face when u drive it one thing ive learned with any car and ive built and daily driven 25+ performance cars since high school is that unless you wanna be disappointed you gotta pick the goal for the car and build it for that a 550hp engine with a street car driveline will not perform like a 550hp can it would take 650 hp to run what the 550hp does with a performance driveline my current toy a 70 stage 1 has a 331 gear a very efficent 4000stall full weight 3900lb with working ac runs 7.20s with more left in it with the stage 2 hood and a cam change I have in store for it ,with bone stock suspension and I drive this car every chance I get and will be driving the 7.5 hrs to the GS NATS with the 3.31 and 4000 stall it will cruise at 75 rite around 3000rpm with the 28 in tall tire

    yea stock crank and rods I polished and deburred long time ago been in a few engines now, Im still playing with verters ive got a 4000 9.5in by RanR out of Asheville NC goin in this weekend I had a 10in "max perf" coan that was actually speced for the new engine that will be going in this spring so it stalled too low for the current engine and hurt track times once the new engine is done and hits the projected 650hp the coan should hit around 4k as well , the heads were done by jim burek long time ago and that's the numbers I was given but im gonna do some more work when they come off , engine made 530 and 580ftlb with a qjet and the b4b

    Contact Scott Brown, TA Performance or Tri-Shield and purchase the cam that he recommends from him. Very difficult to go wrong that way. You'll also get a realistic estimate of the power level you should be able to achieve.

    Spoke to Tim at TA today and told him about my debate between cam selection. the according to Tim, the c107 generates a lot of heat due to the exhaust duration. I would like to run the c107 but i am thinking that the 413 might be a better choice. As hugger said, if i want to get the job done in a quarter mile, c107 is the way to go, but if i want a long legged highway runner, the 413 is a better choice. Unless their is a suggested combination of parts that can make the the c107 a highway runner. I ran a suggestion by Tim of c107 set to 4 degrees advanced, a 3500 stall, and 3.36/3.42 gears. What do you guys think? or should i just go with the 413?

    I like the c107 because it is easier on stock springs and valve train.

    I would think you would want new springs anyway so I would go 413

    stock stage 1 springs a no go?
  20. alec296

    alec296 i need another buick

    Go with a 284-88h now then when change heads go 608 s solid. Stock rods are pushing limits. You will need an sp1 intake with a 950 or 1050 (9375 works well).
