I'd expect the springs to be these (pn 3911068) or equivalent. Same as they used in most all SBC's from the late 60's through the 70's & even into the late 90's on some. GM used them with valve lift up to .460", but the cams had gentler ramps compared to modern aftermarket stuff, so I'd change them to whatever your cam maker recommends.

I called summit tech line and they said with the sumk1104 cam I should get these http://store.summitracing.com/partde...1515&view=1024 springs rated at .490 max lift so I did. Only 43 bucks.
Whats the best way to install the springs with the heads still on the car? With the rope trick or the air trick. With the air trick what and where do i get the valve to put the air in the cylinder. Give me all u know about this. I don't want to mess it up. And any tips on the cam too. thanks for all your help, bob

The compression of the stock crate motor of 8.5..will this be enough for this cam?

Don't use the rope trick. I had a keeper that was stuck in the retainer and I wanted to change it with the heads on. The air compressor wasn't enough to hold the valve closed. I decided to use the rope trick. The rope got stuck in the chamber. I eventually got it out but the valve must have cut a piece of the rope off. It was left behind in the chamber. I ended up with a full teardown to fix a bent piston. If you can't do it with the compressor then take the heads off.

Ok thanks for the tip about the rope.

The guy at summit said the springs I mentioned above would require no machining of the head and I could use the stock retainers, is this true?

Screw-in adapters are sold thru Summit and Jegs and others. I made my own by removing the core from an old spark plug and silver soldering a quick dis-connect for the air line. I set the regulator on my air compressor to 125 psi and everything worked fine. Be sure that the piston in the cylinder you are going to apply the air to is at the BOTTOM of its stroke before applying the air. The air will rotate the crank otherwise. If the pan is off when applying the air you will hear air leaking. This is 'normal' and should be no cause for alarm.

I'm going to stick my neck out here and say that is too much duration for 8.5:1 CR. The motor will have little or no bottom end, I'd recommend another point of compression before using that much cam. Use 270 or less adv. dur and you should have more useable power. (I tried a similar cam in an 8.5:1 motor and it was a dog below 3000 rpm, changed to a 267 adv. dur. and was MUCH better, according to DD 2000 the smaller cam was worth 30+ hp and tq.)
