Excellent point. Cleverly enough, that was one of the original intended uses of these factory 4cylinders in these tractors.One thing you might consider no matter what engine mods you make is to find a Chevy that was originally a stationary power source. GM made them as stand alone power units for things like pumps and generators. Some buses had this type of setup too. These engines would have had an intake and carb designed for use with a governor. This would give you the same control that a typical tractor has. No matter where you set the throttle, the governor would add carb opening to maintain that rpm.
Thank you for all that. Oddly enough, that is my retirement project. Still a few decades out. https://www.youtube.com/channel/UCPUZCBNrduwUsw_MTW-sDxwI wish you luck with what you are attempting to do as I always admire it when people try to learn and experiment. I've given you my best advice but I understand that you have a path you want to follow in your experimenting. I used to fool around with the idea of building a homebuilt airplane powered with an auto engine.
Holy crap! I think that would have been another way to solve my clutch clearance issues i had. NICE! And for the extra mass too. Great idea.There's a youtube video where somebody bolted 5 flywheels onto an engine...
305 has such monstrous torque compared to original tractor engine it hardly needs a heavier flywheel...
But an automatic governor may be a handy idea...
WHOA !!! WHOA !!! WHOA !!! WHOA !!!Ok. I think this is the cam i want. However, they are backordered everywhere.
Ok, thanks for the info. The cam i selected was from a 1969 C30 5.0. 🤷♀️WHOA !!! WHOA !!! WHOA !!! WHOA !!!
You're going the WRONG DIRECTION in cams !!!!
First 194/202 cam (Summit 1101) is stock base level CAR cam for SBC 305, 327, 350, & 400.
HP peaks at 4900 RPMs in a 305.
Second 204/214 cam (Summit 1102) is similar to L81 'Vette 350" / S.S./H.O. L69 305" cam and
HP peaks at 5200 RPMs... We often recommend it as a high performance truck heavy towing cam.
As I mentioned above, need a 1950's SBC truck or stationary equipment cam (Kanter.com, etc.) for a 265" or 283"... or Summit K1100 as largest... The cam you already have is smaller than any of the above, but has narrow LSA and excess exhaust duration...
I have no idea what cam you are talking about.Good (hopefully) Vortec 350 but too big solid roller cam for a farm tractor... prolly around 450 HP at 6200 RPMs...
Looks like a generic high rise dual plane intake manifold...
- Solid Roller Cam. Good High Performance Street Cam With Good Mid Range Torque And Hp. Works Well In 350 C.I. Motors.
- Needs 2500 Rpm Stall Converter, Headers, 9:1+ Compression Ratio And 3.55+ Gearing. Lopey Idle.
- Advertised Duration (Int/Exh): 261/267
- Duration @ .050 (Int/Exh): 231/237
- Gross Valve Lift (Int/Exh): .555/.566
- Lsa/Icl: 110/106
- Valve Lash (Int/Exh): 016/016
- RPM Range: 2500-6500
I went with the cam spec.s listed in the ad and since "L31 Vortec's" are roller cam engines that's what I came up with... guess you'll have to figure out which cam it is... you said you wanted a "solid" cam, not hydraulic... I thought maybe that was the appeal of this engine...I have no idea what cam you are talking about.
The intake is an Engine Quest cast iron marine intake.
Been a long time since I watched that movie. If you look at the 31 minute mark where it shows the airplane flying level, you can see how the engine is tilted upward to compensate when power is added. Personally I was always a fan of the Slepcev Storch. Amazing slow speed control. Then there is the old Helio Courier that makes a vertical takeoff (actually slightly backwards) in a high wind.
