Old Isky Cam

Hello everyone, I'm new here and getting back into building. My first passion with cars has always been under hood, anyway, my question for you guys. Mt last street car I built was in about 90-91 and it was a 70 Nova. I had a flat top 350 with 461 2.02-1.60 heads ported very much on both sides, flat tops, bottem end was a simple moroso windage tray with 6 quart pan, the usual good machine work on crank, rods @ rod bolts ect. I was running a torker 2 intake with a 750 AFB carb and a Mallory mechanical advance distributor, now to my question. I was running a Isky Z-30 cam, solid, 480 lift, 250 @ 050 and 280 total and this thing ran like a striped *** ape, it pulled UNBELIEVABLE from about 3 grand to 7 grand, rest of car was 8-3/4 mopar rear with 3.91's, turbo 350 full manual v body. Is there another cam equal or close to this one, I cant find it on a lot of parts places and Isky doesnt seem to show it. If I did miss seeing it, sorry. Oh yea, I was running a 3500 stall also. The thing was running mid 12's on a good night. Thanks for any info on this mystery cam I cant find.

I'm sure someone can help you with this (most likely Fbird'88) but why not run a solid with a little more lift? There's a lot of other grinds out there than can beat it and with the factory beehive springs going for about $75 a set it seems a shame not to step it up to something atleast around .525".

JMO. Congrats on coming back to building though! I just tore a set of heads apart to send them to get cleaned and milled like 2 minutes ago. Even though they're crappy 493's I still get a kick out of even the basics, like disassembly or cleaning up rough casting.

A compcam 294S would be pretty close and should run even better.

I would also recommend a performer rpm intake with a holley 750 for even more street/strip power.

use zddp oil additive with your new cam. cost an extra 10.00 an oil change but is worth it.

Isky's Z-30 camshaft #201030 is still current in the Isky catalog.

You can buy that cam from any dealer that sells Isky's stuff.

www.summitracing.com
www.competitionproducts.com
Most good automotive machineshops can get this cam and more from Isky.

Many many retail auto parts stores can get the isky stuff for you also.

You can order and buy that cam direct from The Camfather himself.
www.iskycams.com

You are in no way limited to what is shown in the catalog.

The cams shown in the Isky catalog are but a small sample of the cams available from this company. Custom grind cams are their speciality. If you don't see the exact cam specs you need for your engine, or don;t know what cam you need, give them a call. They will help you get the right cam and the matching valvetrain for your project.

Yep, I can verify that they will grind you whatever you want. I was building a 302 Ford street motor several years ago. I wanted a flat tappet solid, but couldn't find exactly what I wanted in the catalog. I called Isky and told the tech what I wanted. He said, oh yeah, we can grind the intake on this master, the exhaust on that master and advance it a little, then cut the cam on this lobe separation angle and bingo, there you go!!!! I gave him a credit card number and the little jewel arrived a few days later.

I like Isky, only used them once as I like to shop around, but they are big enough to do a lot of unique work yet small enoguh to care. Their prices are a little higher, but if you're looking for something in particular they'll usually have it and its well worth the call. I know Erson used to be like that too- can't say what they're like after the buy out.

As Fbird always brings up their lift rule cams work great with stock Vortecs with a spring swap. They'e also on a tight LSA with a single pattern (which I am a big fan of).

BTW, what is your name Fbird? I feel like I should know it by now as often as I run into you.

Thanks everyone for the help. I found the cam on Flatlander and will also call Isky and see if I can't have one ground for this set up. I plan on pretty much trying to recreate this car I had but anything I can do to improve it from a 91 set up will be all the better. I have also figured out a good set of aftermarket heads are the way to go over the old iron stuff after all is said and done. Shoot, the way I'm starting to think, this Nova wont be anything close to the old one, just better! Now I need to dig up a 9" Ford. BTW, I still have the old Hooker Super Comps from that car, been draging em around for years.

REcreate!
Finally after selling too many great cars I wish I had back,
I kept one for 20 years. s

As fast as good old cars have disappeared, hang on to this one.

Also I might suggest going to a roller cam.
I wouldn't be suprised if 5 years from now the anti-wear additives we can pour in to help our flat-cams will be outlawed by the EPA.

Might I suggest looking at a Vortec complete engine. I got one I'm building up now and for the money you really can't beat it. The heads can support an easy 450hp, and upwards of 500 if you port and prep them right. hyd. roller setup from the factory... a 250/250 cam with a 108LSA would be more streetable than your original setup and make more power (though I would take about 5 degrees off the duration). The only problem I forsee is finding a trans to take all the power and then all the tires you'll need to buy.

Call Isky up and talk to them about the difference between hyd. roller and solid flat tappet cams- I think you'll start looking towards the roller stuff.

Get a Vortec engine, ARP bolts all around, Mahle pistons, clevite bearings, port and machine the heads, and a custom cam (most boxed ones are crappy compromise IMO) with a RPM intake. If setup right you'll be running high 11's consistently.
