Happy with the 200

Post #1 by B RON CO » Tue Oct 23, 2018 5:18 pm

]Hi, the happy ending is it all worked out.
To remind everyone, I went over 200 I got from a guy on this site. Rings, bearings, Comp cams 252H, adjustable timing chain set, and the late model head with 2 barrel Holley 350 cfm carb, and new HEI ignition from Bill.
The reason I went for it is because the clutch is 18 years old, with plenty of snow plowing and 2 beginner drivers.
I got over 150 miles so far. The engine is strong, no lag or hesitation. It runs smooth to my self imposed redline of 4000 RPM. I've been cruising in 2nd gear between 15 and 50 MPH and it is very good. I had it up to 65 MPH and it is still strong at 2900 RPM. Much better then the 170.
So how high are you guys revving your engines? I wonder about going much higher. I'm under the impression that going to 5000 RPM happens pretty often.
I do have 3:50 gears and 31 X 10.5 tires on the Bronco.
Here are some pictures.
Good luck]IMG_20180811_155502411_HDR.jpg[/attachment]

I cannot help you, I have not had a 200 with stock pistons. But Jahns cast 6500 , Arias forged 7200.

Great, i'm glad the engine performs as described. On your 350 Holley you could jet down to 60 or even 59 on the main jets.

Good info and driver impression for all that want to have a hopped up 200 for their Bronco. I like that high performance sticker on the air cleaner. Nice clean execution also.

"...how high are you guys revving your engines?..."
I like that Q commin from a long time bronk 170 owner. As David sez:
"Yes, it gets that (this?) good."

Hi, I would be fine with tuning the carb.
I have the stock 62 jet, 31 squirt nozzle, and red pump cam set to #1.
Should I leave the nozzle and pump cam alone?
I think the white pump cam is stock.
Thanks

:beer: congrats B RON CO, looks great and that 1930's Ford pickup looks like it's coming along too! As to how high you can rev a 200 yes it will be dependent on the parts used in the build, as a generation a stock cast pistion block can go safely go to 5000 to 5500 RPM depending on which Pistions are used. But then again dose it really need too, when dose the cam stop pulling anymore or when do the valve springs have enough seat presure to go any higher? Or in orther words when you start feeling the engine lay down and stop pulling (making power) then there's no point in going any higher in RPM. Good luck :thumbup: :nod:

So i ususally suggest only revving the engine to what the cam can support as trying to push it past that point doesn't really give you much for power. That particular cam is rated to 4500 according to comp so honestly i would rev it to 4500-4700 and that would be the shift point. I think babying it for a little while as your breaking in the rings and seals isnt a bad idea but dont worry about give her the goods to that 4500 rpm :beer:

I agree with this post except that I would drive it like I stole it, but that's just me , something between would be good.

My cast iron rodded 1981 with 1963 170 head ran to 5300 rpm often.


The E0 head can support 5500 rpm in a 3.3, and 4800 rpm in a 1980 4.1.

5500 rpm is safe, especially if you have forged rods.

Port size governs peak power rpm. The reduction in cross sectional area takes off about 500 rpm, so even a 200 with a small log 170 head can rev to 5300 rpm with ease. The inside log head runners are about 1.625" in diameter, the earlier 170 head, only 1.125".

The direct mount 350 Holley has nice big carb holes.




With C1 170 spec head, with its tiny 1.125" ntake runners, a 1.3" carb hole verses the 1.625" runners and 1.6875" intake hole from the E0 head. The loss to usable peak rpm was about 500 rpm.


Your most likely safe to 5800 rpm with any 200; it has very little crankshaft oil "windage", and everything was well cast and engineered through all years....except for the downgraded cast iron conrods for 1978-1980 250's, and most 1978 to 1983 200's.

Bigger cams, log heads, carbs are only good if the rods aren't cast. Cast rods don't last a lot of high rpm abuse.
