Anyone got a 1961 or around that year. info on a st-37r roller cam? i need @ .050 numbers. thanks
Why don't you e-mail Racer Brown and ask?
And please come back and tell us what it is if you would.
i did about a week ago. no info from them yet. but i did got ahold of the guy grinding racer brown cams nowdays. he said it was a cam with 282 dur. with .460 lift and about 240-250 @ .050. it was so old of a cam he didn't know the spec's but offered to measure it for me if i set it to him. but i will measure it when i put it in a block. i got a 350 i'm going to put it in. i will be putting it in a 10.5 compression .040 over 195cc headed 350 with 1.6 rocker arms with a set of comp cam roller lifters and a rpm intake and 750 carb. hope it will run good on the street. the lobes are oval shape and should be easy on parts. thanks
Man that is old school! A roller cam with only 460 lift, but I guess that was big back then since a bored out 283 was the biggest they had.The first cam I ever bought way back when was a Crane hydraulic with 280 adv.duration and even smaller 429 lift.Really all it did was have a lumpy idle,I don't think it even helped power.A few years later Comp introduced their 268 High Energy with a huge add campaign so I bought one.That was the first design 268 which had a 108 LS.I really liked it as the car went from low 15's to 14,0's with only a cam swap.Ooops did I get off topic?
Anyway, tell us how you came about that cam and what shape is it in?
got it off ebay. It is new in the box with the card. but card only has open and closing at .025. the pictures i see of it looks really good. the good thing is it's a billet roller so i could regrind it if i have to one day. should be here this week. i like running old school mixed with new stuff. it trips my buddies out they never heard of racer brown or anyone that's not main stream now days. i once built a s-10 with 305 heads with 1.94 and 1.60 valves. i ported them and put them on a 350 flat top motor with a old school 292 cam with .450 lift and a rpm intake and 750 holley and ran 7.78 in the 1/8. the guys i work with had a AFR headed 350 with a Bullet roller cam that ran 7.63 and i could beat him 3/4 ways down the track before he caught up with me. it pissed him off becauce he knew what was in my motor and he had 5 grand in his.
That is really cool! I wonder what the story on it never being used was.Who knows huh. I bet it will have a hell of an idle.
45 years in a box.Waiting to be used. i hope it picks up a few ponies too. it is ground on a 107 intake with 109 lobe seperation. my old hyd flat tappet is ground on the same numbers and it would run like a scalded ape.
The old 283 motor I got off my Nephew had an old TRW TP-147(?) 308/246 or so at .433" lift hy-cam in it.
I have the exact spec's saved at work.
i ran a old trw 30-30 solid one time. it made some racket.
An old friend of mine from my calif days.
He sold the company and the guy that owns it is in Ohio Call me at JDS Induction Products (770)-460-6102 and I'll give you the new number.
Most of the ones that I ran were din-o-mite for there day.
