need help for choosing a cam
 

ok my set up is 327 11-1 domed piston camel hump fully ported aftermarket rod
performer rpm intake manual transmission. the problem is the cam i have is a summit 1105 cam 224/234 duration and 465/488 lift the cam run very well but idle is like stock engine . im looking for cam with similar spec but very rough idle
can a put more agressive cam on this little 327 :confused:

Whats the LSA on the summit cam?

114 lsa i need 108

A great old school radical cam is the Isky Z-60 grind.

110 should work well for what you want comp cams magnum 270 should give you what you want it sounded very nice in my 357.

do you have more spec this z-60 cam

Go with a comp xtreme energy cam similar size or a comp magnum cam. You will get a little lopey idle but still get good vacuum. If all else fails get the comp thumpr flat tappet cam but the previous ones will give you better horsepower and torque. It will give you a nice choppy idle and not be too much problems. If you go with anything bigger expect some carb tunning headaches.

Here you go...Isky z-60 solid 292/292 adv. 259/259 @.050 .548/.548 108CL

the z 60 is too much radical

the max i will go is 525 lift 240 dur

Use a Comp 280 mag. It's tried and true, and it has a rumpety idle while still being streetable.

What is the rear gear ratio and rear tire diameter?
What is the max amount of valve lift your springs will handle?
Are you willing to replace the valve springs if nessessary?
Thinking Lunati cam #401A1LUN
This a state of the art Ultradyne Street/strip/oval tight lash design. You can get it from Lunati or Bullet Cams.
Needs 4.10's very responsive in a 327 4 speed with good compression and heads. You'll feel like your feets are half way off the ground.
It will have the idle you are looking for and a lot more power than your present cam without getting carried away. Will need a modified distributor advance curve.

You could do it the cheap way,put a manual choke on it and pull it out a ways and it will sound choppy then push it in when you want it to run decent. ;)

I guess with a manual trans, good gear and a light car I've never been afraid of to radical. The only cam that sounds better than a Z 60 is an L-88. JMO

f bird 88 my gear 4 10 the valve spring are z 28 style suppose to 550 lift?
