Question 73 nova

I have a 73 Nova all stock except for a edelbrock performer rpm manifold and matching 600 carb. I was wondering if it was possiable to drop a Comp 268 cam in it with out having to change heads or valve size?
And i would sure like to hear any other suggestions i may be able to do at a fairly inexpinsive price (im only 18) thanks

Hey man,
You should be alright with that camshaft, however you won't be able to reap the full benefits of the camshaft without having the appropriate valvesprings. those old tired springs that you have just won't cut it with the valve lift and duration that the cam operates at. You could get some budget springs to replace the old ones, but you could have a valvespring binding problem. I would suggest buying a kit from comp cams that comes with the cam, lifters, springs, retainers, locks, and a new timing chain, because all of it will be in vain if that lets go.
theres my two cents.
keep on roddin'! <img src="graemlins/pimp.gif" border="0" alt="[pimp]" />

The comp 268H cam should be a great cam for your car. Its about is big as you should get for a stock converter and rear gear. The 268XE should work to, though your stock valve springs may not be able to take the .480 lift but should. I would recomend adding a set of headers and some good exhaust too, unless your stock exhaust manifolds are good high performance pieces. I say go with 268H, then upgrade the exhaust, and if needed the rear gear. And yes like he said, problably best off to get the whole kit from comp. AND ALWAYS REPLACE THE CHAIN!!!

Stock springs (new) are good to .500 lift and that's about max.
