Technical Winfield 1R Banger camshaft

I googled till I cant google no more. Anyone know the specs on this cam?
If I use V8 flathead valve springs will I still need to make spacers to tighten up springs? Or are the V8 springs strong enough the way they are? I am going by the writings of Jim Brierley that I have read.

 

I just found this from more searching on the forum. May have answered some of my own questions.

DIRECT ACTING (FLATHEAD) CAMS
No. duration lift int. exh. (Clearances)

B 255 .302 012 014 excellent for mild eng.
C 260 .322 012 014 needs good core

All of the cams listed below need other engine modifications in order to take advantage of their capabilities. The "more" cam you use, the more modifications needed. This includes bigger or more carbs, headers, bigger valves, better ignition, etc. Idle gets progressively worse. The best single modification needed to boost performance in a Model 'A' is to increase the compression ratio, next is a bigger carburetor or multiple carbs.

1R 266 .350 010 012 Winfield grind - fast action, decent idle

270 270 .355 012 014

274 274 .350 012 014

M-28 T 280 .355 012 014 Idle starts getting rough

1A 285 .362 010 012 Winfield grind - good compe***ion cam

285V 286 .385 012 014 compe***ion only

410 FI 288 .410 Good top end, Bonneville or Lakes

290 290 .360 012 014

295V 296 .391 015 015 no low end power

270V 278 .324 012 014 flathead or Cragar (1.25:1 rockers)

280V 280 .336 012 014 fair idle, flathead or Cragar

VALVE SPRINGS
Stock installed spring length is approx. 2½ inches. Spring pressure at that length is approximately 32 lbs. Following is a chart giving spring pressures at different lengths. (Model A springs). A Metal cam gear is recommended on all performance grinds and is a good idea even with a stock cam. An aluminum gear works well and are not noisy as some claim.

LENGTH PRESSURE
2 3/8" 40 # (Recommended for stock B or C cam)
2 1/4" 52 # Note: A spacer made from 3/4" water pipe
2 1/8" 62 # works nicely and will stay in place if
2" 73 # cut off squarely, such as done in a lathe.
1 7/8" 83 #

Coil bind occurs at approx. 1 1/2" (with A springs) 60 lbs. pressure, on the seat, is recommended for most "street" cams/engines. 90 lbs. is recommended for racing, a different type of spring is needed for racing engines in order to achieve this pressure.
