    so these are the specs i have now so i guess im on a cam search now.

    72 350 2bb
    4 barrel edlebrock with a adapter (was on it when i got it)
    swapping to a 74 4 barrel intake with a adapter (this is until i can afford a sniper efi only)
    long tub headers
    700r4 trans getting swapped in with a v6 convertor (stalls about 2k)
    dual exhaust with with high flow mufflers
    e fans and aluminum radiator
    342 gears and posi getting swapped in as well.
    hei dist
    heads and intake will be port matched decked and valves mods according to what is best for cam

    im looking at the ta212 the crower level 2 or the level 3 but it looks to big to run in this thing on cheap fuel.

    car needs to run on cheap fuel be able to cruise to 600 miles with my foot buried pretty well. not wanting a stop light queen at all but needs enough guts to get up around stuff if needed. a little lope is welcome. one area that always confuses me are camshafts. idk why i just really dont know the math for some reason. i guess cause ive never really dealt alot with them other than someone saying hear install this. also the less parts i need to swap the better. so if i can run stock springs or inexpensive ones id prefer it.

    I’m sure The stock springs would be OK for the 212 cam but I’m also sure stage one TA springs would help over 4000 RPM. Yes the crower 3 would want a bit more compression and higher octane fuel in most cases

    Then you better stay with the 212 cam or smaller and the Crower level 2 is probably as far as you can go if you want to run 87. Then I would not run the total timing past 34-36. I would at least run the middle grade gas if you want to stay on the cheap side.

    You would be better off with the Q-Jet than the Edelbrock, open adapters on a stock intake just does not work well and your gas mileage will be crap with that set up.

    A 342 gear with a 700 trans, Really? you'll be turning 900 rpm in high gear You need to up that to at least a 355 or a 373 gear.

    Still not sure why you insists on running 87 octane fuel to save $$. On your 600 mile trip on 87 octane gas you'll probably use 40 gallons of gas and you'll have to make two stops. With 91 or 93 octane and some additional horsepower you'll probably use a little more fuel, say 45 gallons? Still have to make 2 stops.

    So, with the difference in cost between 87 and 93 being about $0.40 and with the extra 5 gallons, you'll spend about $20 more using high test on your 600 mile trip. Is that $20 savings worth staying with an 87 octane motor vs. the additional throttle response you'll enjoy by going with more compression? Your call I suppose.

    By the way, you could still run 87 octane fuel with the higher compression motor by turning the timing down and spreading the ramp out further. However you end up going, good luck with your build.

    I’m still with the crower cam, but shoot an email to buyracingparts.com. On a custom cam tell him what you have and want, the fuel is 87 . He can set up something.
    You are putting in a bigger cam on springs that are 50 years old and designed for .400 lift. You need new replacement springs. . Big setback is the carb you have , is not set for this combo and will give poor performance until you get jets and metering rods close to the fuel curve you need. Get an air fuel meter. And the 87 octane is really limiting factor on potential. You may end up with 6-8 degrees of initial timing and 24-26 at full throttle. Really hard to guess.
    also, if you ran 91 or better, you would see it normally does get better mpg. Maybe tune for e85?

    ill be at 1600 rpm at 55? same size tire and gear ration of a mid 90s s10 4wd. a 373 only raises it a 100 rpm and 355 is less than 50. i already have the edelbrock on it with adapters. got around 20 driving it back on interstate? again its just until i can put a efi on it. i prefer the quadrajet but i think it would be a waste to swap to it just to take it back off in 6 months unless i found one for next to nothing.

    well i want to be able to fill up anywhere as well. i get alot of places they have only base grade or two grades only. also its about 70 cents higher for 91 here at times. i see that getting worse.

    on springs is there an certain set i should use? the ta ones or is there another set i can use that keeps me budget minded? im really like the crower sounds over the ta.

    Wow, $.70 difference is a lot. It runs $.40 to $.45 here in Florida.

    nekkidhillbilly escaped mental patient

    right now its about 40-50. it jumped to 70 back when fuel prices sky rocketed and i feel like thats happening soon. big difference when i say drive to florida in this thing and back. add a 100 bucks at least.

    so im going to run the crower level 2 and i may have found a quadrajet for next to nothing. so what should these heads be shaved to or just run thinner gaskets? figure i can sell the edlebrock and come out with some change so thats good.

    i also total off the wall question and this may be the wrong spot for this but the tbi units (sniper and fitech) out now is there an advantage from the 2 barrel over the 4 barrel? i may be wasting my time and money switching intakes if i wont see an advantage for an engine under 350 hp. also the 2 bb units a few bones cheaper.

    I don’t think the 2 barrel efi bolts to a 2 barrel intake. And there are 2 2 barrel intakes. Small and large.,
    I don’t recall you mentioned a year of engine. the crower level 2 would be fine for a 2 barrel.
    1500 at 55 ? That’s low. Carbs do not get efficient until your on main circuit. And you need more torque at 1500 if that’s gonna be your cruise range. You keep mentioning thinner gasket but those only work on early engines. And if it wasn’t on there in the first place you will need a clean up cut on heads and block for it to seal. Just take .020 off head, and the crower cam will increase dynamic enough for you.

    sounds like a plan. 72 350 2 barrel with a 4 barrel stuck on before i bought it all original. 1600 at 55 not 1500 and no i never drive that slow. however stock the car is running 51 mph at 1600 so thats not alot of difference. its highway geared 2.73 and th350 right now. the sniper is 2300 flange so yes it will have to have a adapter but so does the 4 barrel unit unless i buy a square bore intake or spend way more on the spreadbore sniper. but with the efi units are there a loss in performance with a 2 barrel like a carb or do they not suffer from that?

    You maybe able to find a used TA dual plane intake for a reasonable price with people swapping to the SP3. I have the Poston dual plane on my GS with a super sniper and it runs excellent. The center divider is cut down about 1”. For you intended purpose you would only need the entry level sniper.

    Not that I have seen. Efi increases your lower response and torque. The 4x4 guys love these things. you will give up top end rpm/hp. Not much but enough to notice the difference between a carb and a efi. But that works out with the 700 trans and it’s mismatch of first and second gear ratios.

    i havent found any as recent. stock with the dividers removed should do about as good with the spacer/adapter i was thinking though. yeah i dont need anything super high performance for this car. its my highway cruiser just trying to make it come a little more alive and sound decent rolling down the street. if i was building for a super high hp build it would already be swapped to a big block.

    perfect for a street driver though it seems.

    Rock auto can be tough to get money back from they are strict about the return date policy. They sold me a set of 8 pistons and 2 of them were the wrong ones but because I didn't open the box right away I only noticed 2 months later and they refused my refund... I tried long and hard to fight with them but no luck and no $.
