ok - I'm finally getting my new cam tomarrow and will fix my problem with having a peanut in a car that wasn't made with one ... I'm going with the crane 2032. I'm gona buy all new gaskets andus such... Um I've heard something mentioned about need ing a new distributor gear, is this ture? and it so which do i need... I'm going to use the stock spings and lifters for now, thats why im going with the crane w/ the .260 lift instead of the comp with .280... anything else I need??? I'm driving to PAW tomarrow to get the stuff since their warehouse is only 40 mins from my house... I'm sticking with the lifters and springs since they only have 8,000 miles on them since the rebuild...

oh one more thing - if I go with felpro ultra thin head gaskets will I have to worry about clearance?? And will this affect the compression any???thanks...

Kane,

Just askin' but why would you want a cam with .260" lifts? The stock cam is rated at 0.350/0.384". Did I miss something?

And saving the $50.00 for new springs is a poor excuse for using the lesser cam. You'll be spending all that money and time replacing the cam and will probably be disappointed. I'd advise getting the better cam for your engine/car/driving plan and getting the correct springs for that cam.

I would also avoid thinner head gaskets unless you want to risk leakage and eventual replacement. The compression advantage of the 0.015" gasket thickness is minimal. (HINT: GM factory gasket sets can be $$$ cheaper than Fel-Pro, and are probably made in the same place.)

While you're at PAW, ask to see the Comp Cams application catalog. There is an entire section devoted to correct cam application and why you shouldn't raise compression with some cam profiles. It should also outline the need for a replacement naval bronze distributor/oil pump drive gear.

If you are trying to spare the expense of the springs and machining now, you might want to save your cash and plan on a total conversion later. I'm not sure what your budget is like, but the last cam swap I did was just under $1,000.00. That was a completely new valve train (lifters, push rods, rockers, springs, retainers, valves, head porting, cam, gaskets, distributor, fluids, etc.) If you are keeping the stock valves and not enhancing the heads, you should spend less, but don't cheap out on the cam profile to spare the expense of the correct set of springs. This is a really good time to install screwed rocker studs, too.

Just my 2¢

He was referring to cam lift not valve lift.

IMO that cam is kinda weak. I'd choose the comp instead.

 

whoops - that 2 was suppost to be a 4 - .460 - I guess Thats What I get when I post at 2 am

I haven't been able to work for about 2 years from a sickness I've contracted - I just want my car to be at least as fast as it was w/ the l98 cam - the peanut cam runs like **** w/ the stock prom - im guessing since the lobe separation is so different... I don't have money for the springs or anything else - the car is rather undrivable with the current cam and thats all I really want to fix...

Well chit there goes my theory...
I didnt have the Crane cam book at work and so I took a guess...

Thats probably about as much lift as you would want on a 305, more and you have to do alot of other work. I would seriously advise changing the springs if they are stock specs.

BTW, you are driving to PAW? Where do you live?

I live about 20 min away from the sanfornando valley in S. California - they didn't have either cam - I called a week ago and they had both DAMN IT!!! - oh well - I ordered it from summit since PAW said they can't get it for at least 2-3 weeks...

oh one more thing - the stock distributor has a bronze gear right?? or do i need a new one??? - I ordered the crane - I don't think I mentioned that. At first when you guys were saying that the cam was small I was really confused. I really need to read over my posts...

Is the sickness you contracted keeping you up ALL NIGHT????????

 

The bronze gear thing is a really iffy issue... I was talking to my engine machinist about it since the cam I had apparently tore up the factory roller cam gear even though its supposed to have worked with the stock gear. The factory gear on your 91 *should* work, but I would call Crane first and find out what material the cam is... its my understanding that if its a steel billet core, you must use a bronze gear. I would check after 1000 miles if you use the stock one on there, just to be safe.

 

Imports : yeah (i'm sick most of the day and it takes me about 10 hours to get on me feet) - I have actually a few things now - episteen bar, a sudomonis infection in my lungs - a liver protazoa - gerardia - staff - strep... I have a major immune disfunction, so basically its like having aids except no HIV... I almost got over it about 2 years ago but then my dad had a stroke - my grandpa died (cancer) - my mom cut three of her fingers off and there's some other things that I can't discuss - but i'll just say that they stressed me out more than any of those... the stress made me have a total relapse... I don't even know if I can handel doing the cam sawp since I run out of energy really easy... my best friend is going to help me though along with my dad and girlfriend so we'll get this done


Max: Ill call crane tomarrow or tues to make sure - I still have a few days till the cam gets here... - thanks again for the help
