I don't know alot about cam selection so I had comp cams recommend me one. It was for a full size truck. They recommended a 12-235-2. It has a duration of 210-218. lift is 298 308. Not sure if they gave me what I needed or not. I seen someone had a 268 and they really like it. Is this a cam better suited for a heavy truck. This engine has been sitting in my garage for about 8 years and my dads camaro needs a engine. Will this cam be good for a lighter car or should I change it before I put it in his car.
-
Yes in my opinion looking at the spec's a good street cam to get a truck moving. Don't know the spec's of your engine or drive train but the cam is good for a street truck not reved past 5,500 rpm's.
-
Would it be ok to put into his car? Trying to help him out with a engine and this ones just been sitting around. I am trying to remember a little bit about the engine. It is a 350 and I recall it having flat top pistons but not sure about compression. Probably low though. It has a set or world product sportsman 2 heads and a performer rpm intake. I have either a 600 or 750 edelbrock carb that I could put on it. His car is a 4 speed with 3.73. Does that cam seem ok for this?
-
Yes, this cam would be ok for a lite Camaro with gears. This cam is more for low end, torque to get a heavy vehicle moving. If the Camaro with the 4 speed, gears, and the good heads you mentioned, this cam will not allow the full potential of this combination. Your only going to lose above 5,500 rpm's, so I don't know your shift point.
-
thanks for the reply. If it will lose above 5500 rpms I don't think that would be a problem. That seems like plenty of revs to me and he barely drives it. however he just retired and maybe next summer he will.
-
That cam is not much more aggressive than stock... Doesn't sound like a good choice for his car.
-
any suggestions. Nothing to radical. It has power brakes but it is still drums all the way around. Not the best brakes to begin with.
-
I have one other question. I remember now that one of the headgaskets had a slight external leak. I would like to replace them but and they recommend a felpro 1003 or 1010 gasket for the heads. One set is 70.00 a pair and other 100.00 a pair. anyone know what is different about these gaskets and can I run regular small block head gaskets?
-
I won't recommend anything without knowing more about the engine and his desired goal. I'm not one for slapping a cam in an engine and calling it a day.
-
problem is I don't recall what the compression ratio was. Other than the flat top pistons the bottom end is stock. crank rods. I know what heads and intake I have. It would just be a weekend cuiser. Vile you said you did not think that the cam would be good. Should I go a little bigger. What else do I have take into consideration when selecting a cam. I am not wanting a custom grind or anything like that.
-
Can you list as many of the engine specs and driveline specs that you have?
-
Well what I know is engine is .030 over with flat top pistons. Stock crank and rods. That all I know about the bottom end. The heads are 2.02x1.6. 64cc fast burn shape. 200cc intake runner and exhaust 64cc. I have flow numbers and single spring and double spring max lift numbers if needed. It has a performer rpm intake. I have a 600 or 750 carb that I could put on it. Stock distibutor. The car is a 4 speed manuel with a 3.73 rear. Thats all I can think of.
-
Now that I know a bit more of your engine spec's, here is a good cam from Crane Cams, I recommend. Part# 114142, Grind 2050, range 1800-5600 rpm's, manual trans, 3.73 gears or higher, heads, intake. Part# 11308-1 is the spring and retainer kit number. I think a good performance cam for the Camaro. Decent idle too, with a lope.
-
Thanks for the suggestion I will check it out.
-
That cam would probably be alright with a set of tall gears.
