    The 305 in my 1979 Chevy Malibu was starved for air when it left the factory. I upgraded to a less-restrictive filter and that helped. Out of warranty, I switched to a pure synthetic oil but switched again to a natural/synthetic blend to keep oil pressure up a bit. The only thing I did after that was move to a slightly warmer spark plug and I indexed them in each cylinder. I picked up, overall, maybe 22 horsepower and I felt I'd done a pretty good job for a very low cost.

    Just a side note, from experience. The KN top flow lid works the best in a sealed-well cowl hood induction setup. Fresh outside air, no matter the outside temp. If you have a tight engine bay, you can draw hot engine temp down thru that lid, and really kill everything, across the board, with carb or fuel injection.
    If no sealed cowl hood induction, then pull the hood off. Your induction temp will thank you.

      it's an SBC. Many SBC parts are interchangeable. Just keep in mind some 305's that came out of Mexico were prone to cracking. So you can't go too crazy trying to make power. But you should be able to get away with mild cam, good intake manifold, smaller combustion chamber heads, headers, and a 750-850 cfm carb.

      @@ericinMN1970Yes, SBC stuff bolts onto the 305. But, the first gen 305 is hamstrung by it's small bore, maxed out (intake, carb, heads, exhaust), they would make 325HP. No way would you invest that time and money into an underperforming engine. Normal bolt-ons won't generate as much power on the 305 as it would on even a 307 due to bore size (and potentially larger valves). Free (or cheap bolt on) power is a great way to enjoy the 5.0 while saving for your 350 swap.

Yes they've done similar tests but I believe on 383s and 406s in the 500+ horse range. Maybe Torker and Torker II would be more in the running on the milder combo (they did horrible on the higher strung engines.)

      My point was that since an engine is basically just a big pump for air I bet Max vacuum would give you the greatest throttle response off of the primary's. But not necessarily the greatest horsepower. When the secondary blades are wide open. So it would be cool to see on a dyno how much power difference there is between max horsepower at correct timing. and timing at max vacuum as in a nice smooth daily driver setup. Wich one would give better mileage also.

    My cousin does dirt track racing on 420ci and he explained to me that the oil viscosity doesn’t really make horsepower difference but you need low viscosity, thin oil when you’re running 9000 rpm the whole race. because the oil has to flow the engine at high speeds without restriction.

    Love what you guys are doing here. I started working in my grandfathers shop when I was 3, and long before I started putting power adders on engines, grandpa and my dad spent a lot of time teaching me about timing and fuel delivery. Anyone can bolt on new heads, but the real skill with engine building comes from tuning. This is what the next generation of engine builders need to understand, and it's awesome that you're taking the time to explain the ins and outs of basic tuning.. Maybe you could do an episode showing the gains we can get from the old school hot rodding tricks; like plug indexing, off-set wristpin bushings, rod balancing, plug wire shielding/grounding, etc...

    To get an internal combustion engine to START, (I'm being technical), you need 4 facts:
    1) Fuel
    2) Spark
    3) Compression
    4) Timing
    >> That's it. You DO NOT need engine oil. Only if you wish to keep it running do you need engine oil. If the engine will "turn over", (not 'frozen'), then it will start.[e.g.-- small block chev dry, no oil, ('Slick-50'), Lol.]
    >> Note #1 : some small block chev will fire & run for a min 180° off.
    >> Note #2 : When you dropped your HP distributor in & it took more than a bit of rotation for it to drop into place, it is very possible that you over-rotated it when you bumped the motor over with the dyno starter causing the timing to be off by 22 1/2°, (each tooth on a small/big block chev) This would be consistent with your total timing at 38° + or - a few degrees at your loaded RPM. vs the possibility of a defective harmonic balancer, which is very possible but not very probable comparing the 2 issues.

    Oil choice also effects engine lubrication on startup. Thick oil takes longer to get moving from a cold start which causes more engine wear. Thin oil is better for cold starts but reduces oil pressure when hot which may increase engine wear.
    New cars have tighter tolerances and can use thinner oil. I would not use either extreme in my car.

    You should try X1R in the oil. It really does impregnate the metal surfaces and reduce friction. On my own car it immediately started quicker, ran cooler, revved higher, added 5mph to top speed (155 mph) Car is an Alpine V 6 GT atmo. After 8 yrs in storage without being started or driven it started first time. One of the local gas staions had racing fuel at the pump as it was next to a lake where motor boats of all types were regularly exercised. The gas station owner told me he did a science experiment with his kid for a school project. He set up a bearing and tested the effect of the X1R. He said it really does impregnate the metal. V8 Supercars in Australia use it and they get 300 more rpm, 6 more horsepower and when stripping the engine ZERO wear. Apparently NASA found this stuff in the first place and it was on a visit to Nasa that an Australian Supercar Team owner and former F1 driver came across it.

      Perhaps not on low hp engine. I saw another vid on RUclips and on low hp stock engine (iirc a low comp reman 350 making around 250hp with rams horns) and headers made hardly any difference at all believe it or not.
      Then they put roller rockers on - almost no difference again.
      On some engines roller rockers make an improvement, particularly inline 6 Jeep engines pick up 15 hp and of course you need them on any engine if your gonna rev it up, but the point was on a stock SBC they make no difference.

    I choose a 305 engine in my 74 camaro for daily driving, using a 350 or even a 383 was asking for horrid gas mileage and overheating on our hot summer days in crowded freeways like the 405 and 101. The 305 shines especially on long freeway drives where low ET's dont matter, is reliable and smooth, and has plenty of real world power when it counts, in town and on freeway on ramps. All these different carbs do of course make bigger horsepower gains but only come in a wide open throttle, how would they do in off idle throttle response? gas mileage? Holley carbs have a tendency to leak fuel and need alot of attention to keep running plus they will foul plugs and what about their mileage at a steady state cruise? Anyway, for real world in town and freeway cruising, I abandoned holleys decades ago, went to AFB's and found the best throttle response came from the smallest carb they make on my 305 their 500 com afb. Using a combo of 273 gears and tall tires my heavy camaro gets 26 mpg at 60 mph and 2000 rpm. Your best real world gains come from ignition tuning, get a good HEI dizzy, find your best plugs (almost always AC 45 tsx) and pay strict attention to your wires, then jet lean. Now you have a smooth daily driver thats easy on the wallet, get good mileage and is silly reliable, besides being a joy to drive.

      You do have mark on the engine for TDC and on the balancer wheel, but the challenge is that is only every second time the piston is in top that there is a spark. The engine is 4 stroke. Therefore you need to find the TDC with compression.

  • @EricErnst
    @EricErnst 4 года назад

    2bbl carbs are rated at different pressure than 4bbl carbs. That's why you got 36hp from the 450 2bbl to the 750 4bbl. 1 and 2bbl carbs are flow rated at 3.0" Hg. 4bbls are rated at 1.5" Hg. To convert the flow, essentially just divide the flow of a 2bbl by the square root of 2, or 1.414. 450/1.414=318cfm. So that 450 2bbl is basically equivalent to a 318cfm 4bbl. The flow ratings can change by about 8% whether wet or dry flowed and you never know how the manufacturer tested the carb. Oddly enough, 8% is equivalent to 12.5.. an optimal air:fuel ratio at wide open throttle NA.
