    I find it amazing that the wrong info can be put on a card how can that really happen It's not like these cams are flying off the shelves and no one can keep up. I guess I am too technical I like my info to read correctly, but I am a printer so everything has to be correct on the info.

    What if your machinist had the numbers mixed up on cutting your block or heads. ahh no problem.

    ^^Not much difference than having the card correct and the cam ground off....:rolleyes: Still a puzzle to degree.

    When to run a stall convertor?

    The moment you stick in a bigger camshaft

    It only took 7 pages to answer the question.

    True, big cam more converter.. I don’t think You don’t need a bigger cam to need more converter.

    With the current state of converter technology, just about any car can benefit from one. Tight/efficient during normal driving, but higher stall when you need it. the 9.5" that I got from JW is amazing.

    I guess the original question that I should have asked is will my combination of Parts have decent burnout power or I will I literally need a stall converter to spin the tires...?

    My brother thinks I'm stupid if I don't run a stall. Lol. if I do it I'm buying one from jim. I dont have the extra money at the moment to do that though.

    The conversation turned in many different directions. I would have never decked the heads if it wasn't for this post. I'm sure at times you guys have wanted to pull your hair out dealing with me lol. But I'm trying to learn alot.

    I guess there are discrepancies between where the total duration is measured that's why the industry standard is to measure at .50....? My specs at 50 are close to what is advertised. Not sure if I'm writing this out correctly. But anyway...make sense?

    "It's the same cam measured at different places. Not rocket science "

    I think it may struggle some for a brake torque, but once it does it should be able to maintain it as you will get up where your making some decent ho/torque (probably about 2500). .
    But it will depend on tire size and posi or not. Any traction device you have.
    But I’m sure it will pull really well from 2500-5000. Maybe more. Even if it doesn’t rear get tires spinning. You will probably enjoy the acceleration

    Did you get a distributor recurve kit? The smallest thing but has as mich of an impact as a cam . It’s only like 15 bucks. might be able to find local depending on distributor you use.

    A cam increases power by holding the valves open longer, so that the engine can breathe at higher RPM where it can make more power. The downside is the effective power range moves up, so where a stock cam makes power from 800-4500 RPM, a small cam will begin at 1000 or 1500 RPM, or higher. You give up some low RPM power to make much more up top. The TA 284-88H has a power range of 2000-5000. That's where a converter comes in, it gets the engine into the power range quicker. If your priority is the ability to burnout, you will need a good matched converter. Getting all your mechanical ignition advance in by 2500 RPM will help as well.

    Yes. I think I have seen them in autozone. By the hi performance carbs and Chevy stuff

    Don't worry, it will be fine just degree the cam when you put it in and it will run like a SOB.

    22-2500 convertor will make it run great don't put so much into this If the cam comes on at 2 grand a 2500 convertor will make it scream I already know from all the years of running this 350 at 3 grand the engine starts to do its thing That is where it needs to get to so you can move that heavy boat. Especially when a cam gets installed.

    Stab a 342 gear in there and it will scream some more

    I stuck in a Comp Cam 268 in my 8.5 comp motor in my 71 back in way back and it ran fine I didn't even have a stall in it just a 373 gear and got into the 14.80's then headers duals

    Yes, the cam made it slow out of the hole 2 sec 60 ft but still ran good for a 8.5 comp motor

    I used to have the 260 rear end gear and could do 100 mph in 2nd gear.

    I was beating people at the track with this set up so yours is going to run a hell of a lot better than mine did

    I didn't have all this information in 1983 when I put in that 268 Comp Cam

    Put it together andRock On!
    Happy TG.!!

    Don't you think it might be a better idea to evaluate your ignition timing now? What is your initial timing? What is your total timing, and when is it all in? Is the vacuum advance hooked up, and is it functional?
