I have a IMCA hobby stock 9-1 comp. 487x heads, 3 speed manual, light flywheel, 6.50 gear on a 1/3 mile track the car weights around 3,000# 205 70 15 tires. the track is usually dry. right now I have a small rv cam and I cant hang with the rest of them on the straights. What cam do you guys recommend?


Thanks

call charles at camcraft for a custom grind...

there is nothing perfect for a hobby stock on anyones shelf.

my custom cam from him was 150.00, If I finish higher because of it 2-3 times it pays for itself over a 69.99 cam really easily.

Go to iskycams.com this is the only decent website I have found that has all of the technical data on their cams. Things like compression ratio. powerband, exhaust reqirements, application type, cam lobe angles for all of the different series can be found here. I think most people spend alot of money and never find the proper cam for what they need one for. Take your time and do a little research before you buy and it will pay off at the track! Good Luck!

call holman moody and talk to larry. He can tell you what you need and grind one for about 140.00.

I just had to replace mine and I called comp cams and asked their tech. Motor and track are very similiar to yours. They told me what to run so I called Speedway and matched the numbers( lift, duration ) and got a cam (solid, #915-14102)in a white box for 59.00 instead of the $120.00 I spent on the last comp cam. I run last night and it was pretty awsome, except I need to learn to ease into the throttle now. Its a lot more responsive than the last cam and It got me in trouble last night.
