Inliners International Forums General Discussion Engines 235 cam opinions?

I picked up a cheap NOS cam recently, here are the specs:
Chevrolet, 6 cylinder, 235-261ci, racing cam, Wolverine cams, cam box labeled #G-968, also stamped on face of front journal 968 A93M. Mfg catalog states 3/4 race, solid lifters. Specs intake duration 291, exhaust 275, intake lift .279, exhaust .273, intake valve lift .405, exhaust .387, intake clearance .006 hot, exhaust clearance .016 hot.

Anyone know much about this cam? I'm going to stick it in my spare 235 to try it out.

I am not familiar with that one but .006 is to tight for that. I would try .016 for all.

Good luck. John M., #3370

Crane Cams bought Wolverine in 1994. They may be able to give you information on the cam. http://www.cranecams.com/master/toc.htm#How-To%20Guides

Heres my opinion:
The cam is a dual pattern with milder specs than Crane offers today for Chevy inliners.

I don't think you will see much of an imporvement in the 235's performance. A more radical cam has to work along with better breathing(intake and carb(s), better exhaust (headers, mufflers and bigger tubing), improved ignition (HEI), gears selected for the tires, possible increase in compression(per cam spec sheet), or head work.

Putting the cam is a motor that might have old rings, bad guides, valves, sloppy bearing clearances, low compression, etc will disappoint you. Even if the afore mentioned parts are good, the results may actually make the vehicle drive worse by moving the power peak up to where its not driveable if the motor doesn't have the complementary performance parts installed.

Its best to know all the variables before you install the cam. Get the cams rpm ranges and find out where the cam specs were measure from. Then you will know before your time and $$$ are spent.

Sorry, I forgot to mention that the spare engine is getting a rebuild at the same time but I am not so attached to it that I am not willing to yank it out. It's getting a fabricated dual carb intake and exhaust.

Looking at that link, plymino, Crane Cams does not offer Chevy 235 cams, which are not at all like the later 230/250/292's at all. The head and rocker arm design is completely differant.
